Generally, a deep locker will have a recessed lid. Some modification may be needed to fit locker bags.
Storage is a challenge on small boats, and my new-to-me Corsair Marine F-24 trimaran was particularly Spartan this regard. The skinny hulls provided minimum volume and the race-focused designer intentionally omitted proper lockers. A performance-oriented boat such as this must be kept light if she is to sail to her potential. But even day sailers and racers attract a certain amount of necessary clutter, sure as honey attracts flies. Something had to be done, and yet, as a new owner its tough to know what will best suit your needs and what the boat needs. Its even harder to cut the first hole. This project was 100 percent non-invasive.
With regards to your recent marine oil filter tests (see PS July 2019, Marine Oil Filter Comparison Test), having spent my career in the aeronautical engine technical field specializing in maintenance I must state my allegiance to non-encapsulated filters and independent housings. This trend towards spin-on filter assemblies prevents in my opinion the most important aspect of filter maintenance which is particle inspection. Filters are not removed so you can inspect or replace them, they are removed so you can ascertain your engines condition. This practice seems to have been set aside to make way to quick and easy maintenance using spin-on filters. Oil analysis is fine but it should start with a simple sediment inspection after a low cost electro- sonic cleaning in a 60 Hz bath (jewelry cleaner bath).
Hook and loop fasteners are familiar from jacket cuffs and companionway bug screens, but during our many years of fiddling around boats, weve come up with a few applications that even a Velcro-lover haven't yet tried. Lets look at some new tricks.
In the June 2018 article Air Conditioning for Sailboats, we compared several options for 12-volt air conditioning on boats, and more recently we looked at the power requirements for running our air conditioner without being tethered to shorepower, see Air Conditioning at Anchor, PS June 2019). Since that article was published, we were told about the new i-Line VSD Series of compact air conditioners from Velair-an Italian company that is part of the Ultraflex Group.
Were not naturally bug phobic, but when they eat our food, clothes, or boat, something needs to be done. Since we don't like heavy doses of pesticides in a space as small as a boat, lets first look at low impact approaches that focus on specific pests. After that, well look at the more potent approaches
