Part of what drew us to sailing was the notion that it would be a way to live more lightly on this planet. Once we’re living on Rumiko our physical footprint will be wee, and our ecological footprint will also be quite small (very minor diesel fuel usage, about a gallon of fresh water per person per day, electricity generated by solar panels, etc). But there are aspects of the sailing life that are not so “green.” For example, bottom paint is notoriously nasty . In the past it was laced with metals such as mercury, lead or arsenic. Copper and tin are used today, but are being phased out in many regions of the world. Biocides are also used in the paint. The various toxic products are used to prevent or minimize the build-up of marine organisms, such as barnacles, on the hull, keel and rudder. Different toxic mixtures may be used depending on where one sails, as differences in salinity, temperature and dissolved oxygen levels in water can impact the effectiveness of the paint. The tox...
