The following is an excerpt from the statement that Clipper Ventures released in response to UKs Marine Accident Investigation Branchs report on the death of sailor Simon Speirs. The full response can be found online at: https://bit.ly/36cpUb3
After years of testing fuel products and systems, PS began to suspect that mixed metals in the system could be causing harm.
Something we have long noticed at PS is that gasoline and diesel control samples in our aging and corrosion studies never really age much. Only when the samples include metal samples do they generate gum and discolor. One explanation is refinery stability treatments, but the primary difference is that copper and zinc ions are powerful catalysts for polymerization. Shore-side fuel storage systems do not experience this type of break down because copper tubing, brass fittings and galvanized pipe are forbidden by code . The following requirements are quoted from standards groups and OEMs.
What about fuel bladders? Fuel bladders must meet a higher standard than water bladders, but many of the findings from our water bladder test apply to fuel as well (see Practical Sailor Drops, Drags, and Dissects Three Flexible Portable Water Tanks, PS October 2007).
One of the most common questions we get from new owners of old boats is how to bring back new gelcoat shine. Weve undertaken countless product tests to find the best boat wax and polishes, the most effective waxing-and-polishing tools, and the products that can be used for a speedy touchup. If waxing is on your to-do list, be sure to check out the following articles.
Its not sailing, but weve got to talk about it because its not fun when it goes wrong. The head. Weve reported on the best hoses, joker valves, toilet paper, and holding tank treatments. Recently readers have asked about cleaners that are safe, and sure enough, over the years weve run into evidence that improper cleaning can do real harm.
Practical Sailor wades into the world of thinners and clean-up chemicals.
Different filter manufacturers can chose different rating systems that rely on different statistical values for filtration. The higher the percentage at a given rating, the more effective. Interestingly, the effective rating changes over time, as particles clog up the media, making the holes smaller.
Given the tiny amount of fuel it takes to clear the jetty and hoist sail, our 50-gallon fuel supply can last, quite literally, for years. It certainly lasts through the winter, and all the while, we worry that sludge is growing.
Its getting to be that time of year, when many skippers haul out or head south. Fall also heralds the beginning of boat show season. Here are some PS articles from the online archives that will help you weather the changing of the seasons.
