A New Battery Monitor

by Charles J. Doane, Posted August 15, 2011
Back in the 1990s when I was cruising full time and living aboard a 1964 Pearson Alberg 35, my electrical system was dirt simple. I had two 100AH wet-cell batteries, a battery selector switch, a 30-watt flexible solar panel and a multimeter. When I wanted to know how the batteries were doing, I put the
As a marine electrician I’ve found that in-line fuse holders are the most common cause of problems I encounter with modern electronics equipment. Quality marine electronics are generally very reliable, as long as their electrical connections are sound and there is no voltage drop in the ship’s power supply. Unfortunately, all electronic devices come from the factory with in-line fuse holders on

Fenders for your Tender

A. As you come alongside, it’s often the top of a hard tender’s gunwale that damages the bigger boat’s gelcoat.B. The top edge of the gunwale can be padded with a purpose-made canvas-covered fender strip.C. Some people fit old industrial hose, as shown here; others pad the void and remove the cover if it’s too

Don't Get Zapped

John A. Moore of Punta Gorda, Florida, asks:"Is it true that putting portable electronics like GPS receivers, EPIRBs and handheld radios in the ship’s oven will protect their circuitry in the event of a direct lightning strike?"Gordon West replies:Your ship’s oven will, in fact, act like a Faraday cage, and if properly grounded, most anything

A New Cabin Sole

by David Popken, Posted April 14, 2011
The first time I stepped down a sailboat’s companionway I was overwhelmed by the beauty and abundance of the wood I found below. As a result, I knew one thing I wanted for sure when searching for my first sailboat was a teak-and-holly cabin sole. In the end, I found what I wanted, but the teak and holly was veneer over plywood. It was in less than perfect condition, but having

Beat the Wrap

by Peter Nielsen, Posted April 12, 2011
The last thing you want from your furling gear is for it to jam up in a rising breeze—or ever. I must be some kind of roller-reefing Jonah, because it’s happened a few times on boats I’ve been sailing aboard. On two of those occasions, halyard wrap was to blame.Halyard wrap sounds like something you’d tear off a new piece of rope, but it’s actually the most common cause of

A New Hatch for Keewaydin

by Spencer Howe, Posted March 8, 2011
The forward deck hatch on our project boat, Keewaydin, a 1967 Allied Seabreeze, did not let much light into our dark and dingy forepeak. There was no mechanism to hold the molded fiberglass hatch open, and it was hard to adequately secure from the inside. We decided to replace it with a new waterproof hatch.The Vetus hatch we chose was slightly larger than the original hatch,

Tracking Trickles

by Don Casey, Posted November 23, 2010
Finding a big leak is relatively easy, but a small one can be a major challenge because a boat’s interior is a bit like a room in a funhouse, where water flow often seems to defy gravity. A trickle in the cabin, for example, may be coming from a leak in the deck half a boat length away. Conventional search techniques include 1) flooding the deck by sections with a hose, and 2) building a dike of

Corrosion Stopper

by Peter Nielsen, Posted November 23, 2010
If the green grounding cable on your boat’s AC inlet is connected to the DC ground as the American Boat and Yacht Council recommends, you may be asking for trouble.As soon as you plug into shorepower, you’re connecting the underwater metal on your boat—stainless steel propeller shaft, bronze prop and through-hulls, zinc anodes, aluminum saildrive—to the underwater metal on all the other
