I am a go fast kind of person, so the idea of an open bow never ocurred to me. But today, I was over at a buddy's boat shop, and he had a 23' Searay. That thing had more cockpit room than a 35 Fountain and then had a walkthrough windscreen! I don't know that a 23' Searay would be enough for your friend, but don't some of the West Coast builders make 28 - 30 foot open bow deep-vee boats? Maybe DCB or Advantage or Hallett???
BTW - Shouldn't your friend have asked someone that actually drives an offshore boat rather than someone that just keeps it on the trailer?
