Re: Bob Perry's take on Wolfenzee's dream boat

Thanks Bob - Have read the usual books for neophytes on design and never fully understood this. Still unclear why a narrow boat would be faster down wind. Think I understand upwind but not downwind. Is it simply less wetted surface so less parasitic drag in combo with less frontal plane so less resistance.
Last weekend saw a motor launch at the Bristol museum. It was 40+ feet long and maybe 6feet maximum beam. It had fins like you would see on a 1950's car except horizontal just above the static waterline put all the way aft. Wish I took a picture to post. Looked real cool but wonder why they were there ( had nothing to do with the steering I could see). ?Early attempt to prevent squatting.
