MONTHLY MAINTENANCE
Halos in bottom paint around underwater hardware is a phenomenon I encounter on a regular basis. And just as often, I'm asked: "What causes this? Is it something to worry about?" The answers lie in an understanding of underwater metals and bonding systems.
Most fiberglass sailing vessels rely on metal alloys for through-hull fittings, struts, rudder gudgeons, hinges and so forth. In most cases, these metals are connected by wires (part of the vessel's bonding system) to a sacrificial anode or anodes, which provide what is commonly referred to as cathodic protection.
From a corrosion perspective, the anode-often called a "zinc," even though it can be zinc, aluminum or magnesium-is less noble, and thus more prone to corrosion, than the metals to which it is connected. As a result, the anode corrodes, or sacrifices itself, in order to protect the other metals.

Last Man Standing
During the past four decades, the once-thriving business of American production sailboat manufacturing has nearly vanished, and dozens of companies and builders have fallen by the wayside. And then there's Tartan Yachts of northeast Ohio, which, in some aspects, is as vibrant as ever. Longtime Tartan stalwart Tim Jackett, a marine-industry lion in winter still making a stand, might be the central reason why
Boat of the Year 2024
With sweet, early autumn sailing conditions on Chesapeake Bay, a strong fleet of 19 contenders competed for top honors in our annual Boat of the Year competition.
