hmmm I have seen quite a few builds and repowers were they posted regen stats...on those displays that came with the kits
my thought was that regen actually make sense for voyagers and ocean goers over long periods of time versus say a coastal cruiser that doesnt have access to shore power
for example somoene doing a non stop circumnav or a san fran to hawaii trip where you only use the engine a few times to me electric with regen makes more sense here, since basically you will be regenerating the whole way...
(the regen stats I read up where that most boats started around 4knots putting back into the system, and that if they used a little throttle it would help reduce the motors drag and the prop would spin up easier too...)
anything over 5-6 knots and the amps put back in increased substantially...mostly dependant on prop type.
its like wind power...youll get more wind in steady trades than you will at the marina in bewteen all the boats and structures etc...
my thought was that regen, on long voyages makes more sense, since you dont use the motor untill you get to port or need to anchor etc...
again it comes down to preferences...obviously if you are the kind that motor sails if speeds goes under 5 knots, electric is not for you...
if you have access to shore power and are coastal hopping and marina hopping I dont see where having such a big bank is either necessary or worth comparing to conventional fuel
as when doing so with diesel or gas you never completely use up you tanks either...we didnt for sure when coastal cruising...
the ongoing dilema has always been that in non stop runs electric has maybe 10% the range that conventional boat with inboard tanks has...but if you use it sparingly and have ways of recharging it can and has been done...
those were my thoughts
also I liked the small battery bank conversions for the same reasons, say 4 batteries instead of 8 or 12 or 16...because if depleted it will be quicker to recharge...not only that but he initial expense and cost of chargers etc...goes down exponentially
