Simple Steps Will Keep Salt Out of the System
Depending on the collection area and the sailing, salt can be a primary problem. Spray falls and dries, layer after layer, until the decks hold enough salt to foul a considerable flow of water. The solution? Wash the deck with seawater before the rain comes. Squeegee off as much as practical or towel dry, and common sense dictates this is best done when at sea and must be done away from red tides. We tested the run-off from the top after scrubbing with seawater, allowing to dry, and then spraying with tap water equivalent to 1/10-inch of rain (see results in table below). In addition to taste, seawater contains significant sulfate levels, which combined with bacteria in the tank under anaerobic conditions, can lead to sulfurous water; sailors notice this when a seawater flush is used for the head, but allowed to become stagnant for a few days; the first flush will smell.
Winterizing Wisdom from the Chemistry Lab
Each winter sailors must tackle the project of winterizing their potable water system. Our preferred method is to dry the system completely (see PS September 2014, Step-by-Step Winterizing tips. If thats not possible we completely empty the tank and then treat the plumbing with the correct concentration of anti-freeze. The online version of this article provides all the details you need to carry out this process, as does the recent Inside Practical Sailor blog post, The (Cold) Case of the Frozen Anti-freeze.
Towing Generator Field Report
For free power when under sail on ocean passages, towing generators are hard to beat. In the early 1980s I purchased a first generation towing generator from Hamilton Ferris. At six knots the output was five amps providing all the electricity I needed on passage. During 15 years and 100,000 miles of use I only needed to replace brushes and bearings twice.
Stopping Anchor Chain Twist
When an anchored boat spins, the anchor chain twists, and the anchor can come up backward. One solution is an anchor swivel, but failures with some poor designs are a concern-a lovely stainless swivel on one of our test boats had an interior crack that became visible only when disassembled. And as we found in our most recent test, many swivels arent very effective at reducing twist due to the inherent friction in the swivel.(see How Well Do Swivels Reduce Twist, Practical Sailor March 2016 online).
Short Scope Anchor Test
In the process of our ongoing investigation on the effect of time and wind gusts on anchor setting and holding capacity, we performed limited testing at short scope and couldnt help but notice that holding capacity at short scope varied greatly. When recovering the test anchors, some anchors would lift out of the bottom while we were pulling the dinghy over to them, while others required heroic efforts even when the rode was nearly vertical.
Setting an Anchor in a Small Boat
In our ongoing study of ways to compare, and hopefully improve the way our anchors set, weve learned that it takes time and slow, delayed setting to make best advantage of very soft mud. However, firm sand and weeds can have the opposite character-making it hard for the anchor to penetrate.
Sleep Routines for Long Passages
The US Navy has finally gotten around to a serious study of watch standing schedules (https://goo.gl/dE4W4R). As an active duty Navy Medical Officer, I certainly saw enough injuries related to sleep deprivation; fortunately, none were as disastrous as the recent collisions. I am glad to see the navy move away from a centuries old approach to scheduling watches.
2017 Top Sailing Gear
Each year, just prior to the fall boat show season, Practical Sailor editors consult with our testers to come up with a select list of Gear of the Year from the previous 12 months of testing. For most of the 2016-2017 testing season we focused on essential everyday products that owners of boats of all sizes-with a few exceptions-rely on. While our testers appreciate new technology, they recognize that a safe passage often depends on the reliability of the weakest link, and that weakest link is often a seemingly minor component that gets little attention. In short, our Editors Choice list is not the sexiest product roundup, but if youre serious about keeping your electrical connections corrosion free, making professional repairs on a blue-collar budget, maintaining a safe speed in a steep following sea, or looking for a way to manage a big genoa without upgrading to an electric winch, youll appreciate it.
Making a Safe Landfall
I feel for the crew of Tanda Malaika, a family of six whose 46-foot Leopard catamaran was lost on a reef on the southwest corner of Huahine in French Polynesia in July this year. The loss is especially acute because, as the captain himself points out, it could have been avoided. The account of the wreck, provided by the skipper/owner Dan Govatos, and recorded in the podcast Slow Boat Sailing offers important lessons for cruising sailors.
Skipper Recounts Capsize 57-foot Atlantic Cat
Charles Nethersole has been a professional sailor for decades, and in addition to racing commitments and deliveries, hes accrued 14 years of sea time as a professional captain aboard 55- and 57-foot, Chris White designed, Atlantic catamarans.
