Clean Marina Minute -

Any oil in Any oil in the bilge puts you at risk for an overboard discharge.
Petroleum products discharged from the bilge are no different than spills at the fuel dock. Any spill that creates a sheen on the water can bring hefty fines. Here are some tips to prevent petroleum products from mixing with bilge water:
• Keep your engine tuned to minimize oil leaks.
• Check that clamps and filters are sealed properly.
• Inspect hoses and belts for peeling or cracking.
• When replacing hoses ensure they are the correct length, hoses that are too long or stretch to fit are prone to kink or collapse.
• Place an oil-absorbent pad under your engine and an absorbent bilge sock next to (but not interfering with) your bilge pump.
• Wipe up spills, drips and splatters immediately.
• There are many oil-only absorbent products on the market that can help make bilge maintenance easier. Some are oil-only absorbents that absorb oil and leave the water behind, others contain microbes that "eat" the oil over several days or weeks making disposal easier.
• Another alternative in dealing with dirty bilge water is an inline bilge filter. This device is designed to remove petroleum products from your bilge water without restricting bilge pump performance, allowing for a clean discharge. You must periodically check these products for oil saturation and replace filters as needed.
• If absorbent pads and filters haven't done the trick, a few marinas now offer a bilge pump-out service. It's still a new concept, so check with your local marine facilities for pricing and availability.
• Bilge cleaners can be a tempting solution to an oily bilge, while they can seem effective, many of these cleaners just suspend the oil in the soap and then both are discharged. If you use bilge cleaners try using a small amount on a cloth and use a hand bilge pump to remove to a bucket and dispose ashore.
A Note About Bioremediation
Absorbent products such as booms and socks that contain microbes or claim to "eat oil" may be used in the bilge of a boat. It is not legal for boaters to use loose or contained bioremediation products on a spill in open water. Only a trained spill response professional can legally apply these products to an open water spill.
For bioremediation products to work in your bilge they require the presence of a small amount of water, air temperature above 40 degrees and several days or weeks to be effective. In theory, after given enough time, the microbes will consume all of the oil or fuel, leaving behind clean water. Bioremediating products make disposal easier but do require time some as long as weeks to months to get rid of the oil.
SHM Rules and Regulations Reminder
Bilge pump absorbents: In case you didn’t know; the Marina has a SPILL KIT on the dock! Inside you will find absorbent pads, booms and a pump! This pump was used recently to save a dingy from sinking! If you don’t know where it is, walk towards A-Dock and you will see it on the main dock or ask your neighbors. It is important to know where this is in case you need to help a fellow tenant save their dinghy too.
The Benefits of eating Locally
- By Laura Brownwood
Eating local foods is healthy for you, the environment and the community. By choosing locally sourced goods you’ll be adding the freshest tasting foods with more nutrients! Here are a few tips to help you.
Learn what’s in season. Knowing what’s available in your area and when it’s at its prime will help you plan grocery lists and menus. In no time, you’ll be searching markets and farm stands for zucchini in July and for butternut squash in late-September. Bonus: in-season produce is often less expensive than out of season fare. You can find local organizations that give advice about what produce is available in your area and where you can buy it.
If you’re a landlubber, plant a garden, or even just a few plants! Herbs are easy to grow on windowsills, and pots of tomato plants will thrive on porches. Also you can check out the VegTrub, available everywhere:
If you live on your boat and lack the space, you can join a community garden where you will have your own plot or garden with others to grow your own food. There are MANY in San Diego county! Here’s a website to locate the one closest to you.
Locate the farm stands in your neighborhood. Local farmers large and small are selling their produce at roadside stands where you can buy whatever is in season: tomatoes, strawberries, zucchini, and squash. Especially in east county. You can also shop at larger farmer’s markets, where multiple farmers and artisans will be selling their goods. Again, San Diego has many to offer. Check labels and look for local produce. In addition you can find bread, jams, grains and other products that are grown or produced near you. Many grocery stores and even restaurants are using signs or labels to let you know where your food is sourced, making it easier for you to choose the products that are made right in your neighborhood.
We are fortunate here in San Diego as we have our own Edible magazine. This publication has information about upcoming markets and festivals.
I’m very proud of my company, USANA. We have a humanitarian project, Garden Towers, which are large heavy mesh bags filled with soil, that hold up to 120 plants. They are only 3 ft. in diameter, making them accessible to families living in some of the most impoverished conditions in the world.
In light of that, let’s appreciate where we live and all that is assessable to us. And . . . Yes, your mom was right . . . EAT YOUR VEGETABLES

-By Captain John
Sail long enough and you can bet you will come across a vessel that shows a bunch of black geometric shapes hoisted in her rigging.
These are called Day Shapes. Day shapes may be shaped like a ball, a diamond, a cone or a cylinder.
Single day shapes or combinations of day shapes are required to be shown when a vessel has a specific type of work or status that restricts their movement. They might be unable to get out of the way of another boat or ship. Day shapes are displayed from sunrise to sunset.
Today, let's talk about some of those combos. Start with the Ball-Diamond-Ball (middle of the cluster below). The Navigation Rules states that the vessel restricted in her ability to maneuver due to the nature of her work, must show a Ball-Diamond-Ball grouped in a vertical line
Look at the last few words of this Rule "...due to the nature of her work...". I've given a lot of 100-ton license exams as a pro maritime instructor and taken exams many times. Those last words can trip you up big time if you do not read them word for word. Here's why...
Those words do not refer to a vessel with an engine problem. Nor do they indicate a sailboat with shredded sails. Or a sailboat that has been dismasted. Or a boat with a jammed or broken rudder. Sure, all of these vessels may not be able to get out of the way of another vessel.
But, their status has nothing to do with the "nature of their work". Other shapes are used to cover circumstances where a vessel has experienced a disability of some sort.
Look over this list of vessels that show the Ball-Diamond-Ball configuration:
* Tugs with tows that severely restrict their ability to maneuver.
* Vessels servicing aids to navigation (i.e. Coast Guard buoy tenders).
* Vessels launching / recovering aircraft (i.e. Naval aircraft carriers).
* Commercial or recreational dive boats (may hoist a rigid replica of the Alpha flag instead).
* Vessels engaged in underwater dredging or operations.
Some vessels, like those engaged in underwater dredging or operations, have to carry additional day shapes on each side of the vessel. Note in the illustration the two black balls and two black diamonds on each side of the Ball-Diamond-Ball. What does this mean?
How to Decode Multiple Groups of Day Shapes
Think of these as "danger side / safe side" indicators. A vessel engaged in underwater dredging or operations, must show two black balls in a vertical line on the dangerous side of passage and two black diamonds in a vertical line on the safe side of passage
Use this memory key: "Balls are Bad; Diamonds are Delightful". Pass the dredge on the side with the two diamonds. Look at the illustration again. See if you can decode each group. Ball-Diamond-Ball means what? Ball-Ball means what? Diamond-Diamond means what?
See how easy that is? Use this same "one group at a time" method with any cluster of day shapes or navigation lights that you see. It melts away the confusion in a heartbeat! Works like a charm.
Vessels engaged in underwater dredging or operations are the ONLY vessels in the world that show these three groups together. That's really important to understand. There are vessels that show two black balls in a vertical line (and no other shapes), but they are not dredges! (find out more in my eBook - see below).
Why You Should Verify Before You Commit!
When I taught at the Chapman School of Seamanship, one of our instructors came back after a weekend on the water. A dredge was working in the inlet, with limited room to pass on either side. He saw the Ball-Diamond-Ball along with the Diamond-Diamond on one side and Ball-Ball on the other.
But--something just did not look right. Not right at all! So he stopped the boat and called the dredge skipper. And, guess what? The skipper came back on the radio: "Sorry about that; we forgot to switch the shapes when we turned around". Oops. It happens.
As you might know, commercial crews can get so busy that they might forget to tend to those small tasks that may not seem so important. But of course, small things we forget can sometimes have unintended consequences. So, give the skipper a quick call on the radio. Just in case.”

Leaving a Slip in the Wind
Learn five tactics to get away from the dock when the gusts are against you.
1. Wind Pushing Starboard Side, Stern Out
Step 1: Hard left rudder. Engine forward will kick out the stern.
Step 2: Reverse engine with left rudder, after releasing line and clearing dock.
Step 3: Forward out of the marina.
2. Wind Pushing Away from Dock, Stern Out
Step 1: Engine forward and right rudder kicks out the stern.
Step 2: Engine reverse with left rudder after releasing line and clearing dock.
Step 3: Forward out of the marina.
3. Wind Pushing Port Side, Bow Out
Step 1: Reverse engine, right rudder to pivot bow into the wind.
Step 2: Remove line and steer into wind.
4. Wind Pushing Away from Dock, Bow Out
Step 1: Release bow line first, then stern and power forward with right rudder.
5. Wind Pushing Starboard Side, Bow Out
Step 1: Reverse engine, left rudder to pivot bow into the wind.
Step 2: Remove line and steer into wind.
A challenging maneuver for any boat (power, sail, big, small) is leaving the dock. Slow speed makes a boat less maneuverable because the rudder isn't very effective until the boat's going fast enough for water to flow over it cleanly. Called "steerageway," that efficient speed can be elusive when the wind's pushing you back or when you make turns, which also slow the boat.
Before heading out, check the wind strength and direction, and then plan your tactics. The illustration shows five ways to cast off from a slip and head out of a marina into a head wind. It's a two-step process. First, clear the slip, using docking lines and the engine to control the boat and prevent rubbing against the pier. Be careful, though. The forces can be larger than they appear. Then point the bow as directly as possible down the channel and get going. On that heading, turns will be gradual, which improves your speed and control

||Sailing to Catalina for the First Time
- By Richard Benscoter
One of the most idyllic and fun places to visit on your sailboat in southern California is Catalina Island.
For some boaters though, taking that first trip to Catalina can be a little daunting with all the do's and don'ts we have heard about over the years.
Obviously, there are many ways to get to Catalina from San Diego. There is the direct route where you go to San Diego's Buoy # 1, turn right and set the course and go.
The direct journey is 72 nautical miles to Avalon, and depending on the cruising speed of your boat this can be hours on a power boat or many hours on a sailboat.
In my Catalina 36 "El Marinero" it takes 12 to 14 sailing hours depending on the speed of the prevailing current and sea state.
When to go? I prefer to make a daylight crossing for a couple of reasons. My night navigation skills are not as sharp as they were when I was in the Navy as I don't regularly use them. Plus, my body clock prefers a normal wake sleep cycle.
Also, a problem that would be minor during daylight can become a difficult issue in total darkness.
For example - look at your key ring. When you pick it up during daylight you immediately identify the key you need - but step into a totally dark environment and that simple task becomes more difficult. When I do go direct to Catalina from San Diego I leave the dock a 4:30 Am which will put me at the # 1 buoy as the sun is rising, and in Avalon before dark.
Another way to go to Catalina is by harbor hopping up the coast. This is a great way to go and see the coast and sights along the way.
For example, a fun first day is to go from San Diego to Mariner's Cove in Mission Bay and anchor for the night. Mariner's Cove is a nice place to chill, and only two hours from San Diego Bay so a mid day start is not a problem.
Then Mission bay to Oceanside is only about a four to five hour sail and the guest docks are within walking distance of restaurants and small harbor shops
From Oceanside to Dana Point it's about four hours where you can anchor in the northern harbor anchorage. (There is a southern harbor anchorage but it is also occupied by the bait barge - not the finest bouquet or aromas). Dana Point harbor has restaurants and small shops to explore.
From Dana point you can go the 33 nautical miles directly to Avalon or take another hop to Newport for the night at a mooring or guest dock.
For a sailboat, this is usually a great beam reach sail from Newport to Avalon, and only 24 Nautical miles, in about four hours.
Finally, you could hop to Long Beach - the closest harbor to Avalon. Long Beach Harbor is huge and there are many marinas that have guest docks. I have found that the north part of the harbor is best and I enter the harbor at Angel's Gate. From Angel's Gate to Avalon is 22 nautical miles.
Nautical miles between harbors on a direct rhumb line.
- Mission Bay to Oceanside: 27 miles
- Oceanside to Dana Point: 22 miles
- Dana Point to Avalon: 33 miles
- Mission Bay to Avalon: 63 miles
- Oceanside to Avalon: 45 miles
- San Diego to Avalon 72 miles
A Salvage Boat Race Story
- By Kells Christian
We marine surveyors are often racing during salvage operations racing the tide, racing weather and we're always racing time.
We have been active with salvage jobs during Covid, and during a recent round of sea stories during a salvage in the Central California coast, I remembered a very interesting salvage boat "race"
As marine surveyors we usually represent insurance companies and insured's interests during salvage operations.
The historical basic concept of salvage is to reward a salvor for risking their health, life, and equipment in order to save someone else's property, usually a vessel or cargo. In return for the risk, and usually based on the value saved and level of risk, the salvor is granted a reward.
Two decades ago a Catalina 42 left Southern California for Hawaii. Aboard were the owner, a friend of his, both in their sixties and two of their children, both about twenty.
Right away the vessel began experiencing problems including water intrusion and somewhere approximately 100 miles off-shore there was a steering failure. Only one of the 20 year old's was able to steer with the emergency tiller handle. A decision was made to abandon the vessel and all four passengers were retrieved by a Coast Guard helicopter. The EPIRB (acronym for emergency position indicating radio beacon) was activated.
As a representative of the insurance carrier for the vessel we hired a salvage / tow boat to retrieve the vessel and initially had good location information from the EPIRB.
Just after we initiated the recovery of the vessel, we were alerted to a second salvage vessel underway in hopes of retrieving the Catalina and collecting the reward.
Initially I was dismayed and contacted the owner of the company who had dispatched the competitor salvage vessel. He responded that this was "only business" and "may the best boat win". His boat was faster.
I asked an authority, providing the EPIRB information if the location could be selectively provided, i.e. withheld from the competitor boat. I was denied. We, the good guys in my opinion, were not the favorites to win the race but with both tow boats racing toward the abandoned and adrift vessel, the EPIRB signal began to wane.
As the two tow boats approached the area in which the vessel was believed to be, its EPIRB became completely useless. We hired a spotter plane to assist our team and developed a communication protocol so they helped only our team. Without premeditation on the part of the land based team, the pilot of the plane, on his own, provided information to the competitor vessel. We later learned the information was inaccurate.
The hero salvage vessel won the race, found the Catalina 42 and returned it to its home port and its owner. Had the competitor vessel found it, they would have been granted a salvage reward for their effort but in this case instead, they got their just reward a fuel bill.
What You Can Do to Prevent Oil and Fuel Pollution From Your Boat
Here's one of the most complete checklists we've found to help you prevent oil and fuel pollution from your boat:
1) Preventative engine maintenance:
- Keep the engine well tuned and operating efficiently
- Practice preventative engine maintenance. Inspect fuel lines, hoses, hydraulic lines, valves, oil seals, gaskets and connections for deterioration and leaks.
- Properly secure lines and hoses to prevent chafing, abrasion and damage
- Choose Coast Guard-approved alcohol-resistant fuel lines.
- Install drip pans under all equipment that might leak
- Avoid using solvents or toxic chemicals to clean engine parts. Use mechanical means (such as hand scraping caked oil) or less toxic solvents (water-based).
- Do not let solvent run into the bilge
- Transfer and remove fluids with care using funnels, pumps, and absorbents to eliminate drips and spills and to keep the bilge area clean.
2) Bilge care and preventing oil spills:
- Never use soaps or detergents to clean oil or fuel it is illegal and increases the pollution problem
- Install an on-board bilge filtration system that filters gas, oil or diesel from bilge water before the automatic bilge pump discharges the water.
- Use oil-only absorbents in the bilge; securely fastened to prevent clogging the bilge pump or its sensor, to capture unexpected leaks
- If you have a large quantity of oil in the bilge, use a bilge pumpout system
- Never use the sewage pumpout for the bilge
- If the bilge and/or engine compartment still needs significant cleaning after bilge pumpout, use a steam cleaning service.
3) Report oil and chemical spills:
- If you see or cause a spill, do not apply soaps to dispense the sheen (it is illegal).
- Report spills of oil or chemicals to the Marina Office and to 800-424-8802
4) Spill-proof your oil changes and recycle used oil:
- If you change the engine oil yourself, use a closed system a portable vacuum oil change pump drained into a container that can be closed to prevent spills during transfer of oil (available at most marine stores).
- Do not mix used oil with other waste. Keep it segregated for recycling.
- Recycle used motor oil, oil filters, and fuel filters at a used oil recycling facility. Click here to find a facility close to you.
- Always keep oil-only absorbents on hand to wipe up spills.
Saturated oil-absorbents are hazardous wastes and must be disposed of at the marina, the fuel dock, or at a hazardous waste facility.
Leech Lines and Longevity
- By Brad Poulos
All sails today come equipped with leech lines or cords that enable sailors to stop that annoying flutter between the batten pockets on your mainsail or up the entire leech of your genoa. This flutter usually gets more pronounced as the wind increases and in some cases can get so noisy, it becomes difficult to hear anything else.
In the days of Dacron sails, adjusting the leech line was a matter of eliminating a nuisance, nothing more. Today, many cruising sailors and virtually all racing sailors use laminate sails, which places a new importance on properly adjusting the leech line to prevent damage to the sail.
For example, let's consider the leech area in your mainsail between the clew and the lowest batten pocket (see photo). At the very edge of the sail, there is a Dacron tape that encloses the leech line.
This tape usually extends 1-2" into the sail and then you are left with whatever laminate the sail is made of. When the leech flutters, the laminate bends or hinges back and forth just inside of this tape and as we have all seen, this frequency of this bending can amount to hundreds of times per minute in a stiff breeze.
To get an idea of what this is doing to the laminate, straighten out a paper clip and flex it back and forth a couple of times. The result is obvious! Of course the metal in a paper clip isn't nearly as flexible as a sail laminate, but Mylar film and some high modulus yarns used in racing sails do break down rather quickly when flexed.
So I'd like to offer some words of advice:
- Pay attention to the leech of your sails and adjust the leech line when the edge of the sail starts to flutter.
- Make sure the leech lines and cleats are adequate for the job. For instance they should be a low stretch line and of sufficient diameter to hold in the cleat. On large genoas, you may need a mechanical advantage (2 or 3:1 or even a small tackle). If your leech line cleat gets stripped and fails to hold the leech line, tighten the leech line and then tie it off until you can get the cleat replaced.
- Your mainsail leech line should be able to be adjusted when the sail is reefed; notice the cleat just above the reef in the picture. Cleats on the leech of the sail cannot be adjusted when the boom is eased out over the water; therefore, some offshore mains have two leech lines, where the second one is led over the top of the sail and down the luff to a cleat at the tack.
Even More Shocking! Galvanic Corrosion
- By Commodore Vincent Pica
When we wrote about Electric Shock Drowning last year, we were also setting the table for a related and more common problem which is called Galvanic Corrosion. The same elemental forces that could translate into ESD will definitely create an environment whereby your boat's metals can "melt away."
What Is Galvanic Corrosion? When two dissimilar metals are in contact with each other, the base requirement for galvanic corrosion is in place.
What does dissimilar mean? Well, how about a bronze propeller and a stainless steel drive shaft? Or stainless steel screws holding aluminum trim tabs in place? Or just the grounding strap on a boat, connecting all the various metals? But more than contact is required.
An "electrolyte" has to be present too a substance to conduct electricity (the flow of ions) between the two dissimilar metals. And an excellent electrolyte is seawater. What happens is that the more "noble" metal (bronze, for example) destroys the less noble metal (aluminum, for example) by dissolving it, ion by ion, in favor of itself. This is galvanic corrosion.
Clearly, the best idea to have your boat protected with zincs, the least noble metal available, so that the zinc is "sacrificed" at the expense of all other metals.
Zincs should be placed on the running gear struts, on the transom (in the water) and on any internal part that is in contact with seawater like a raw water cooling system. However, if you have plenty of zincs and the boat next to yours doesn't, physics will require that your zincs protect both boats simultaneously (and without your knowledge) until they "melt" away exposing you and your less diligent neighbor to the full onslaught of galvanic corrosion.
What Can I Do? Well, you could disconnect the AC green ground wire from the boat's ground point. This will break the circuit and fully halt the corrosion cycle. However, this is a very dangerous condition. Electricity can "jump" from your AC system to your DC system simply by the wires of the two systems being in proximity to each other. Out through your engine block to your running gear and into the water. (See last year's column on "Drowning Shocking!") Clearly, that danger is far higher than worrying about a prop dissolving before your eyes.
So, a Galvanic Isolator would do very nicely! It sits connected to the green ground wire, close to the shore-power inlet. It blocks, quite simply, the flow of ions between your boat and everybody else's.
The Galvanic Isolator also has a "trip" system (via something called a diode) that stops the low-voltage galvanic action from occurring but will allow dangerous AC power build-up to get to the ground, if any.
The better Galvanic Isolators have something called capacitors built in. They allow even low levels of AC to pass through. Stray AC current, as pointed out in the "Drowning Shocking" column points out, even as low as .01A, can paralyze a swimmer so you want it running to ground as efficiently as possible.
So, don't go swimming at the marina, make sure you have and maintain your reservoir of zincs and maintain that green grounding wire in good condition. The life you save may be your own.

Selling Your Boat? The Top 10 Things To Do Before You Show
- By Bob Sherman
Selling a used boat is not unlike selling a home. Presentation is everything. Here are some recommendations to follow to get the maximum return.
1. Have your boat professionally detailed inside and out; don't forget the engine room and the bilges. Dollars spent here are well spent.
2. If it smells; it won't sell! After you do step one, spray all compartments with a natural liquid enzyme spray. This actually breaks apart the molecular bonds of odor causing compounds. There are many sprays on the market but one that we found works really well is Pure Ayre.
3. If the carpeting is worn or has that 1970s "Harvest Gold shag carpet" look, have it replaced. At the very minimum, have your carpet shampooed.
4. Replace any canvas and isinglass in poor condition.
5. Service the engines and generator if needed and change fluids if overdue. Ask the maintenance company to also inspect hoses and change zincs if necessary.
6. Remove excess clutter from the boat - Of course, also remove anything you don't intend to sell with the boat.
7. Do a pre-sea trial if your boat has been sitting for a while. Make sure it can pass a sea trial - being towed back in by Vessel Assist will not impress a potential buyer.
8. Repair known and obvious deficiencies if practical or be prepared to make survey allowances for them.
9. Keep the boat clean and fresh inside and out during the sales cycle.
10. Lastly, wonder why in the world you didn't do steps 1-9 so you could have enjoyed the improvements while you had the boat!
It's also a good idea to interview brokers to discuss their experience, general knowledge and marketing plan. A professional Broker can offer opinions as to what other improvements would be cost effective.
The more things on the list that you do, the faster the boat will sell, and the better the price. While the above items require some investment, "You never get a second chance to make a good first impression!"
Some Things We Bet You Didn't Know About San Diego
The Hotel Del Coronado was the first hotel in the world to boast of having this feature. Do you know what it was?
Before it was named San Diego Bay it was named something else. Do you know who named it and what it was called?
We all know the Coronado Bay Bridge has that beautiful sweeping curve. The designers of the bridge must have done that for the aesthetics - or did they?
Many people, including a number of San Diego natives, assume the ferry boat docked at the Embarcadero and housing the Maritime Museum of San Diego is one of the early ferries that connected San Diego and Coronado before the bay bridge was built.
However, the Berkeley, an 1898 steam ferry boat, did not originally serve under the blue sky of San Diego. She operated on San Francisco Bay, even acting as a rescue vessel after the 1906 earthquake.
Even though not a part of San Diego's history, in 1973 she became the San Diego Maritime Museum's offices, store, and library. She also supports the Museum's events and education programs and acts as a polling place during elections.
The Hotel Del Coronado:
The first hotel in the world to boast of completely electric lighting. Thomas Edison himself inspected the steam generator used to power this accomplishment.
Architect James Reid, however, was a man to hedge his bets. Gas lines were installed to each room and the electrical wiring was run though them. In this way, should the electrical system fail, they could resort to the known technology of gas lamps. Some of this original wiring was in place as late as 1965.
We can only be grateful that they did not have to resort to the backup plan. Electricity running through wiring that is inside formerly used gas pipes installed in a wooden hotel - frightening thought.
The "San Diego" Bay: On September 28, 1542, Juan Rodríguez Cabrillo hung a right turn while coming up the coast from Mexico and "discovered" San Diego Bay. He named it San Miguel after St. Michael the Archangel because it was the day before the feast day of St. Michael.
About sixty years later, another Spanish explorer, Sebastián Vizcaíno, came sailing in on November 12, 1602 and re-discovered the bay, which he re-named San Diego after the patron saint of his ship.
The San Dieguito migrated here across the Bering Strait land bridge somewhere around 9000 to 12000 BC and the local Kumeyaay Indians settled on the bay around 1000 BC, but since Juan Cabrillo was the first to record a name, he generally gets the credit for "discovering" the bay.
The San Diego-Coronado Bay Bridge:The American Institute of Steel Construction apparently agrees. In 1970 the Institute bestowed the bridge its Most Beautiful Bridge Award of Merit.
But the Bay Bridge's sleek lines and sweeping design with that 90 degree turn in it are not for aesthetics alone. You might have noticed San Diego has a few Navy ships around, including aircraft carriers.
The bridge rises to a height of 200 feet, high enough to allow a carrier to pass beneath it. The curve and the bridge's length of 2.12 miles allows this to be done while keeping the grade at 4.67 percent.
If it weren't for the curve, it would be so steep you'd need a dune buggy to get up and over the thing.
