Would electric winches be allowed?
A fuel cell is a generator, using methanol to produce electricity. https://www.efoy-comfort.com/how-it-works
Using electrical power to cant the keel is legit for the race seems against the spirit of the event. Using a fuel cell seems a little further down...
Is the Schock 40 going to have to cant their keel with a hand pump? Typically it's an electric pump. Seems like that is electricity being used to make the boat go (adding or removing righting moment)? Same could be said for the figaro2 using an electric pump to add water ballast.
