As a follow-up regarding the gear reduction - it seems to me the formula used by Thunderstruck is very much aimed at monohulls...I'm not sure how many large cats they've sold kits to.? Having 2 hulls and 2 motors seems to me to make that equation even more complicated so I'm leery of trying to plug our numbers in to their form as a way of deciding what gear reduction to order.? And he was also suggesting the 96v 24kw motors, which seems like massive overkill.? As much as I like everything they have to offer, I'm just not sure their thinking aligns to a cat as well as it does a mono.
