: What, mistakes? Me? Heaven forfend...

: But seriously, Re: the overall beam, one of my design criteria is to allow a
: swimmer to lounge around between the hulls in the stern to rest, so I am
: working with a 12-16" spacing - I think the 24" overall beam is
: optimistic, it will probably be more. The greater beam may be offset by
: the higher seating position of the paddler, allowing a higher paddling
: angle even though the beam is wide. I will play around with crossbars of
: various lengths to see what effect it has. A speedy version could have
: very narrow separation. I think the boat would lend itself well to a
: sailing rig with greater hull separation. I've made some sketches of a
: rowing cockpit (similar to a Skimmer Boat), which could be made quite
: narrow. Hey, if the drag is low enough, I could see putting hydrofoils
: between the hulls below the waterline - I have plenty of potential
: test-pilots on crew here at school - that would be a lot of fun.

: Re: the bows, I do have them quite narrow at the moment to give a very fine
: Swede-form shape - the half-angle of entry is only 3 degrees which does
: not increase along the hull. To counter burying, I plan to use a NACA foil
: as the front crosspiece similar to some lifeguard skis (or whatever
: they're called). On the model it's just a flat plank at a guessed angle -
: I'll make the prototype anti-pearling plane adjustable hopefully and see
: how (if) it works. I may increase the flare above the waterline in the bow
: just to be on the safe side.

: If you have any other thoughts about this design, by all means I'd love to
: hear them. I showed the model to a bona-fide, working naval arch and he
: didn't laugh, gave me a couple of ideas and told me about the original Sea
: Sled, so I take that as encouragement from a pro. I have a big fear that
: the boat will be very susceptible to being bullied about by the wind, but
: am going to proceed anyway.

Hi Carl,

Well I wouldn't worry about the wind, if anything these things should be considerably better than the average kayak, they have knife like hulls that are fairly deep in comparison.

Btw, the term I was struggling with is prismatic, a way to define the fullness of hulls.
