Re: 23 Seacraft Hull Design and the Silverhawk
Jimmy:
Welcome to the site, silverhawk was a seacraft, close enough [img]images/icons/wink.gif[/img] seacraft variable deadrise hull, softer ride due to its vee- like shape; min. of water deflection, air pockets created by steps and the natural stiffness that the steps provide. most experts regard the seacraft hull design as one of the softest riding boats in rough water on the market. It's notable softer riding than many boats with deeper vees.the low deadrise[flatter] outer panels of the seacraft vdh hull design and the reduction of the vee shaped displacement created by the steps into the vee shape of the hull give it far more lateral roll resistance than comparable pure vee hulls. BOY that was a mouth full. [img]images/icons/grin.gif[/img] ................steve [ May 13, 2002, 08:00 PM: Message edited by: steve ]

Re: 23 Seacraft Hull Design and the Silverhawk
Jimmy....welcome Thats a real nice boat you have there!!!
Yeah all the stuff Steve says....plus...I think and I emphasize THINK .... that is an average measurement of deadrise angle. Since the boat literally has three different planes, each carrying a different degree of deadrise....they get averaged together to come up with that number....therefore the angle from the keel to the first strake is very close to 25-30 degrees (second plane is something like 16-18 degrees and the outboard one is 12-14 degrees) averaged together give you the 20 degree deadrise (for SeaCraft that is) Additionally our boats have a real sharp entry which helps alot.... Has anyone else heard this theory ???

Re: 23 Seacraft Hull Design and the Silverhawk
You hear the term variable deadrise kicked around a lot, some even refer to the difference between entry and transom deadrise as variable - well no Sh*t ! The thing about the Seacraft hull is really those distinct steps, the vertical edges of the steps provide great tracking, the steep center deadrise gives you a soft ride while the outboard flatter deadrise adds stability.I believe the design was patented in the beginning, but has since run out and I've wondered why you don't see more manufacturers using it these days ?

Re: 23 Seacraft Hull Design and the Silverhawk
BOY STEVE AND SCOTT SAID IT ALL.
FOR ME THIS IS THE BIG “WHY” THE TRUE KNOWLEDGEABLE BOAT OWNER’S GET SEACRAFTS, AND “WHY” THERE IS NOT A BETTER 23’ BOAT ON THE MARKED AND “WHY” ANYONE WOULD BE WILLING TO SPEND ALL THE TIME, $$ AND ENERGY TO RE BUILD ONE. FELLOW-SHIP [img]images/icons/wink.gif[/img]

Re: 23 Seacraft Hull Design and the Silverhawk
Potter tells me he wants to get a hold of an old Seacraft hull and incorporate some design improvements he has come up with and test them.Could be an interesting project.

Re: 23 Seacraft Hull Design and the Silverhawk
Mr. Potter has remarked several times about his desire to implement and test a redesigned hull but I do not know what his ideas are.He is on vacation till next week.When he returns I will ask him about the design of the original Seacrafts and his ideas about changing and why. [img]images/icons/tongue.gif[/img] Nothing to do with the bracket alltho building it into the hull would'nt be a bad idea.I think he wants to redo the bottom to make it ride even better somehow.
