Personally I consider flush toilets and absurd thing to have on a
boat..... One of those features of modern life that never really belonged on yachts, and has resulted in some really disgusting situations......... composting makes sense in enclosed waters.... off shore "bucket and chuckit" or "direct deposit" makes the most sense.... Human waste in the open ocean is NOT a pollutant any more than that of
marine mammals or
fish.... pollution is a function of concentration as a
rule. Most of the things we regard as "pollutants" are only pollutants because they are concentrated in a small area.
Bravo on eliminating through hulls..... My ambition is to have a
boat with ZERO through hulls..... which is realistic with a
catamaran or
trimaran, but not with a
monohull.... Sea
water cooling is a real trouble spot on any
engine....There are a lot of arguments against radiators on boats, but anything in contact with sea
water will get fouled, and is subject to
corrosion..... I've toyed with all kinds of ideas.... Considering the low horsepower in many boats, it should not take a lot to cool them...
