Ask Sail

Mike Keller of Arlington, Virginia, asks:”I recently upgraded the two lead-acid batteries on my Catalina to 79Ah Group 24 AGMs, and I’m thinking about wiring them in parallel to double my available power supply at anchor. I’d also add a small PWC battery for use as a starting battery. We don’t have refrigeration, but we do have lots of other gizmos that use power.My

Rick Conner of Panama City, Florida, asks:”I made the mistake of filling my water tanks without first filtering the water. Normally I put a filter on the end of the hose, but this time I didn’t. Because the town water pipes are fairly old, I’m thinking perhaps some rust might have gotten into my tanks. Is there a way to get rid of the orange-colored water now coming out of

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

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

Do you winterize your own engine, or do you have the yard do it? I take the former approach, for three reasons. As my dad used to say, if you want to be sure a job’s done properly, do it yourself; I’ve seen some pretty sketchy work done by so-called marine professionals over the years.The second reason? It seems silly to pay someone to do a job that’s a) not very time-consuming, b) not at

One of the best mini-projects I’ve done this year is to replace most of the halogen light bulbs on board with LEDs. I’ve always hated halogens; so much of the energy they consume is wasted as heat that they are models of inefficiency, and that same heat can actually be dangerous if something flammable is pressed up against a light fitting. The fact that I have scorched my bald spot countless

Leon Lieberman of Ambler, Pennsylvania, asks: “The center headsail halyard on my C&C 33 needed replacing, and a crewmember accidentally pulled it out without attaching a messenger line to run the new halyard. I’ve been up the mast twice, but can’t get the new halyard to feed in over the sheave and down the mast. Any thoughts on how I can get the halyard up and over the

Rene Etherton of Chicago, Illinois, asks:”When we’re anchored out my audio system works fine, and we get great reception on our HD LCD TV. But back in our marina we get a loud hum on the audio system, and TV reception from several stations is always breaking apart. Why does this happen?”Gordon West replies:I’m almost certain that the hum in
