63urban, Could you provide an example? All of my research indicates that solar powered propulsion (except for auxiliary) is a dead end.
Like I tried to show Rick, most of the wattage calculations that I have seen regarding electrical power seem to be off by a factor of 9.8 (gravity).
Believe me I would love to put a dozen solar panels and some batteries on the boat and cruise around forever at 5 knots.
What I am now attempting to do is use the wings for propulsion and the solar panels and batteries for the boats systems. Almost complete independence^^ and the ability to move along at 10 knots plus.
