Re: [Electric Boats] AC vs DC motors - new EC cat

 

Thats true. If it doesn't pull a wake and doesn't push a bow wave, theoretical hull speed is not nearly as relevant as with a more conventional hull. Consider for instance a high speed SWATH hull. Definitely not a hydrofoil. Definitely not planing. But easily exceeds the old 1.34 x  WLW. Multihulls with very narrow hulls behave similarly. Sure there is still a penalty for going fast, but it isn't quite as big a deal as it is with a classic monohull shape.
