As for the capturing of engine heat to use for distillation, I just have
a hard time seeing that the engines used by the typical cruiser, as

The equipment was on the market at one time[1], although RO may have
killed it off. The idea was to stretch water supply and gain fuel
capacity. As in ocean crossing in powerboats. A sailboat just doesn't
have the fuel burn needed to make a lot of water.
