I’d did say “hard if not impossible”. The bigger (windage), the heavier the boat, the harder then, the more expensive, it is to do. I do like the idea of an internal pedal set up though.Gotta disagree on this one. Look at what Team Elsewhere did - they had an internal two person bike powered setup, so they could pedal inside. The bigger the boat gets, the more inside room for pedal stations and crew. Plenty of room for an internal 4 person pedal team on that Riptide 44. I imagine they would move along smartly and in comfort. Ok maybe not easy, but certainly not impossible.
Mad Dog got towed out to the PT start line in 2016, P&W looks like they sailed at least part of the way out of Victoria this year. Eventually, one year, there will be a 25- 30 knot South Westerly blowing into the Victoria start for a couple of days.
Maybe an exAC72 cat? All the pedal stations are already built in? Or imagine 50/50 with 2 or 3 in line pedal stations in each hull!
