When it comes to onboard water tanks, we prefer stainless, fiberglass, and even roto-molded tanks (in that order) to aluminum ones. Aluminum tanks tend to pit and corrode over time, often needing to be replaced. The insides of the two 60-gallon aluminum water tanks in our 30-year-old Valiant 40 were more like a nasty moonscape than a drinking source. Their surfaces were pitted and rusted from what looked like a reaction to long-time use of chlorine.

Editors note: Designing, installing, and wiring a new main circuit panel on a full-fledged cruising boat is an extremely challenging refit project. The writer is a professional engineer who made sure that his installation met or exceeded American Boat and Yacht Council Standard E-11. Failure to adhere to the standard could result in fire, injury, or death. We offer the following article, which outlines the steps involved in constructing a custom panel, as a rough guide. In our opinion, such a project should not be carried out without the consultation of an ABYC-certified electrician.

Gelcoat provides a fiberglass boat with a hard, water-resistant protective shell. When new, its polished and waxed to a bright shine, but after a few years of facing the elements-especially damaging UV rays-gelcoat will begin to oxidize and turn into a dull, chalky film on the surface. There are a few ways to remedy an oxidation problem (see Tips & Techniques), but for this article, we focused on coarse and medium-coarse rubbing compounds, which can be buffed on to remove the chalky layer and fine scratches. The tests evaluated ease of use, ability to remove oxidation and scratches, and whether they left swirl marks; testers also considered price, availability, and eco-friendliness.

Practical Sailor tested the compounds on the badly oxidized hull of a neglected 1974 ODay Javelin daysailer that has been stored uncovered in the Florida sun and salt air for years. Formerly the platform for gelcoat restorer and wax tests, the Javelins once dark-blue hull had degraded into a chalky, light blue mess.

Over the years weve owned Josepheline, our 38-foot Lightwave catamaran, weve figured out a few simple fixes to some niggling onboard problems-some boat hacks, if you will-and we thought wed share a few in the hopes that other boat owners may benefit. If you have any little fixes of your own that youd like to share, email your story to [email protected].

Lately, readers have been asking us about which antifouling paints serve well for specific bodies of water (or type of water). So, in this article-our annual spring bottom paint report-we will try to answer these questions with some recent reader survey data and sales reports from the two biggest brands in the U.S. (Pettit Paints and Interlux Yacht Finishes). But before we get into the regional breakdowns, a quick recap on choosing bottom paint and our paint testing program is in order. If youre a longtime subscriber, feel free to skip down to the Current Testing section.

Its been 12 months since testers mounted the 12 nonskid test panels on the roof, subjecting them to south Floridas semi-tropical weather around the clock, without any cleaning. The test field included the big names in marine maintenance products-AkzoNobel (Interlux and Awlgrip), Pettit, West Marine, and Epifanes-as well as companies specializing in nonskid paint, Pachena (KiwiGrip) and Durabak, and three that make nonskid mats, SeaDek, Tiflex, and Soft Deck. With the service life of nonskid paints and mats ranging from three years to a decade or more, we didnt expect to see much change in the test panels, but there were a few surprises.

Revamping a nonskid deck is not a project most boat owners look forward to doing. Here are a few tips to help you get more mileage out of those arduous nonskid restorations.

Over the past five years, in our search for the best bottom paints, weve reported on three sets of bottom paint test panels that have been in salt water for two years or more. Most panel sets contained the same roster of 60 to 70 antifouling paints from Blue Water Paints, Epaint, Interlux, Pettit, Sea Hawk, and other makers. In the end, only seven antifouling paints proved capable of combatting barnacles after 24 months. We consider these to be the most reliable bottom paints available for the cruising sailor.

Most sailors have discovered that when it comes to applying marine coatings, the type of masking tape used is as important as the type of paintbrush if you want clean edges. But what is the best tape to use for boat varnish projects, or bottom paint application? Testers compared eight of industry leader 3Ms general masking and specialty tapes to find out.
