Batteries And Your Boat

Brett Dingerson

I overheard a conversation in the electrical aisle of a local marine supply store the other day which caught my ear. A boat owner had asked for assistance in replacing his batteries because his current batteries didn’t seem to “hold a charge”. He also asked how long a battery should last; his were only 3 years old.

To my astonishment, the salesperson said “I’ve known batteries that have lasted 10 years; maybe you should try to equalize them”, and proceeded to completely confuse this fellow with a half-baked explanation of batteries and their problems which might be solved by raising their voltage and blasting off “sulfates”, thereby restoring them to health to last another couple of years.

One thing I’ve learned in 30 years, folks, is the golden rule of batteries. They last as long as the manufacturer warranties them, and not much longer. People that manufacture batteries know exactly how long they will last.

The most important thing for a boater, however, is that batteries are not a luxury on a boat. They are the cornerstone of a boat’s electrical system. Batteries power everything aboard a modern boat. Sure, a sailboat can sail into safe harbor, but people with the skill to sail a boat into a slip aren’t in abundance.

Currently, there are 3 main types of batteries available:

1) Lead-Acid

2) Gel Cell, and

3) Absorbed Glass Mat (AGM)

Lead-acid are the most common and the least expensive. Gel Cells can last longer and are quite a bit more expensive, but they eliminate the need for maintenance and are a good choice if your batteries are in an inaccessible location. AGM batteries are currently the best of the readily available batteries, but can cost as much as 5 time as much as lead-acid. They are normally guaranteed for 5 years and are very dependable. They are heavier than lead-acid or gels due to a manufacturing process that can squeeze more material into the standard size battery case.

I never attempt to “rescue” old batteries that have marginal life remaining. They are a primary piece of safety equipment onboard a vessel, and I refuse to send any of my clients out to sea with batteries that don’t have my complete confidence to produce power when needed.

While it is true that equalizing batteries on a regular basis is a good thing, it can only be done on lead-acid batteries that are not sealed. Equalization involves raising the voltage to around 16 volts and basically boiling the electrolyte. Trying it with sealed lead-acid, gel cell or AGM batteries will ruin them, and could cause them to explode, spewing acid everywhere.

Properly taken care of, batteries will supply power when you need it. When batteries become questionable, have them tested and replace them when necessary without resorting to efforts to save them. They are way too important an item to try and squeeze pennies about.

America’s Cup and You

Stars & Stripes USA-11

Ever wonder what it would be like to catch the wind at the helm of a Stars & Stripes racing boat? Well, now you can! In a brand new San Diego charter experience, you and your friends can experience sailing aboard USA-11, the 78 foot racer used by Dennis Conner in the 1992 America’s Cup Race.

A totally different kind of sailing experience, participants have the opportunity to volunteer to experience the thrill of the helm or take a turn on the “grinder” under the guidance of Captain Lynn Hanna.

Participation in crew duty is completely voluntary, so the less adventurous can simply serve as “rail meat” and just enjoy the ride.

In any event, everybody who brings a camera on this unique charter will go home with proof of their participation in a great adventure. If the circumstances and the wind are right, it’s not above Captain Hanna to engage in a bit of friendly “competition” with some of the other boats on the harbor which adds to the excitement of the adventure.

USA-11 is berthed at the Kona Kai Marina on Shelter Island. For more information about booking a reservation on USA-11, call (619) 255-4705 or (866) 250-3568 or visit www.sailusa11.com.

Port Commissioners Approve Lane Field Development Concept

Old-timers remember that the huge parking lot at the corner of Broadway and Harbor Drive (opposite the cruise ship terminal) used to be Lane Field, the Home of the San Diego Padres from 1936 to 1957.

On February 13th, the Port Commissioners approved conceptual plans for hotel, retail and restaurant development on the site. The visionary plan, which has been under development for ten years, calls for the development of two hotels, approximately 50,000 square feet of retail and restaurant space, a 100-foot wide esplanade along the bay, expanded view corridors and lush landscaping along harbor drive. The proposed hotel designs feature sail-like forms on the hotel roofs and glass walls that simulate ocean waves. Read More...

Greetings From Your Marina Manager

Welcome to Shelter Cove Marina’s March 2007 e-mail newsletter. If you’re reading this before Sunday March 11th, remember to set your clocks ahead one hour on Saturday night for Daylight Savings Time. Then on the following Saturday, March 17th, whether you’re Irish or not, we hope you’ll have a festive St. Patrick’s Day.

A Thank You For Your Help In Managing Hazardous Materials

Recently, our marina docks were inspected by the Port District, and we are pleased to report that only a handful of minor infractions were reported. We’d like to thank everyone who did receive notices regarding these infractions for their prompt attention in correcting the problems.

We’d also like to take the time to note that the Coast Guard has been conducting surprise inspections at marinas checking the contents of dock boxes and has been issuing fines, in some cases to both the boat owner and the marina. So although you’re probably tired of hearing it, it’s important that you know that storing any toxic or hazardous items in dock boxes is absolutely prohibited. For a list of hazardous items, as well as literature on green boating habits, please see the marina office.

Some Additional Reminder Notes

Personal dock boxes are also prohibited; all dock boxes must be provided by the marina. They can be rented for $10.00 per month. Also prohibited are personal For Sale signs displayed on boats. Brokers may display signs with pre-approval. Fishing from the docks is absolutely prohibited. While it may seem a fine way to spend an afternoon, fishing from the docks poses potential hazards for safety and property damage.

Your Cooperation Is Much Appreciated

We like to keep the marina “rules” short and sweet, and we thank everyone for your cooperation. If you need a complete list of the marina rules and regulations or have a question, please contact the marina office. Our aim is to provide an attractive and friendly environment for all to enjoy. Happy March! “Spring has sprung; the grass is ‘ris - I wonder where the flowers is?”

The Beat Goes On

The subject of licensing boat drivers comes up over and over, and every time it does it sparks a heated debate. Coast Guard Commandant Admiral Thad Allen threw flames on the subject last December when he said the potential for a terrorist attack launched from small boats means that states and the Coast Guard must cooperate better to watch who is on America’s waterways.

Critics counter that licensing boat drivers won’t do anything to stop terrorism, however, many do endorse some form of mandatory education as the number of new people driving bigger boats without a clue increases.

If you want to see just how hot this issue is, type the words Thad-Allen-Licensing in your favorite search engine.

Be on the Lookout!

Bob Sherman

Recently there have been some boating accidents in San Diego…collisions with fixed “hazards to navigation.” As they say, “A collision at sea can ruin your whole day.” You “old salts” are probably aware of these, but those of you newer to our harbor should take note. If you don’t already have one, get yourself a paper nautical chart of San Diego Bay, or find it in your “chart kit”. Even experienced boaters will find it wise to review the chart from time to time. Use a highlighter to mark an hazards that you find.

There are many others, especially south of the bridge, but here are some prominent hazards, starting at the harbor entrance:

Zuniga Jetty - A submerged jetty along the East side of the channel at the harbor entrance, usually visible at low tide. Marked by sign posts and lights every quarter mile. This jetty has claimed many boats!

Shoal area south of Ballast Point - This unmarked shoal, just outside the channel, near buoy 11, has mean depths of 4-6 feet. At a minus tide, the depth will be lower still.

Submerged Jetty off North Island - Opposite Ballast Point, do not sail or cruise inside the white/orange spar buoys. An unmarked, submerged jetty lurks inside!

Both Ends of Shelter Island - There are shoal areas on both ends. By the time you read the sign on the West end, you’re already into the shoal area. Don’t “shortcut” the entrance.

Piers and Jetties Along North Island Naval Air Station - Older charts will not show that the Navy added some pilings and visible short jetties off North Island, as you are curving around the bend toward downtown. A boat ran into one of the old piers at night recently, which are unlighted.

Mooring Buoy off Harbor Island - This large mooring buoy (FM19) is often unlighted. It is located just East of Sunroad Marina’s buildings.

Shoals Near the Coronado Bridge - It is safest to pass through at the wide span, in the main channel. There is a large shoal area right in the middle of what would seem the logical “shortcut” into Glorietta Bay. The shoal extends to the red nun buoy on the South side. There is also a large shoal extending from the Naval Amphibious Base, All the way to green buoy #1!

South San Diego Bay - As mentioned - Lots of shoal - Too many to list here. Stay in the marked channels and consult your chart!

Mission Bay International Airport?

Not many people know or remember that in 1943, an entrepreneur named Arnold H. Peik opened a small general aviation commercial airport on the southwestern shore of Mission Bay. By 1946 he had a 2,600foot oiled runway and three hangars. During its relatively short lifespan, the airport was listed under a somewhat confusing succession of different names. The City bought Peik out and closed the airport in 1957 in connection with the development of Mission Bay Park. It is believed that Peik’s airport was also used to some degree by the U.S. Air Force.
