VDH Hull on Sailfish Boats

You would be surprised at what a difference that little strake makes,that's why it's there.And it has nothing to do with making it any drier,23 foot boats are not dry.It's there for lift and softer ride.

I don't know much about hull design, but that little section is already out of the water when the boat is at rest, and most boats don't need any help lifting the bow when underway. [img]/images/graemlins/confused.gif[/img]

My 78 Secptre has the extra strake, but my 70 20SF does not.
Maybe one of our SeaCraft historians will know more about that addition.
See ya, Ken

The 18's also had it although the 20's didn't (and still don't).

Yes, you don't know anything about hull design.I am not a marine designer either,however,I have been a licensed (100 ton )Captain since 1979 and driven everything from SeaCraft's to million dollar Merritt's from Maine to Key West,the Bahamas,Mexico and Carribean for a living.And I'm here to tell ya' that when you put the pointy end of any boat into a sea the strake creates lift and air under the hull so that when you drop back off the sea you don't pound.Again,that's why they are there.

I'm pretty sure we are not talking about the same thing. You might want to re-read the thread; it’s not about the nature of lifting strakes. BTW, driving a big boat doesn't give anyone knowledge of the intricacies of fluid flow dynamics. [img]/images/graemlins/wink.gif[/img]

C'mon now Roger ! I ran a 186' Supply Vessel & I cared about Fluid Flow Dynamics ; Only I called it Ballast ! Same thing right ? Oh by the way I gotta pretty BIG ticket (C.L.) along with the other documents/cards that come with it. Heck My unlmtd AB card took longer to get than most Capt. Lic. Ok so they stretched a 20' seacraft & put the pretty girlie Bayliner top cap with all the stuff there that'll eventually crack,fade & break. They do look nice but then the SeaCraft was designed to be fast & Fish ! They made the original & coined the fraise BowRider for the others. You want storage get a seaBag.
18 's bow boats & 23's had the lift strake 20's did not & there is a noticible Diff. In ride & splash ! But then being born in La. I gotta get wet OFTEN ! Otherwise I'd have a TRAWLER!
& I ugh what the @%^^$# is this post all about now ? Sheet time for a BEER ! or a shot o Turkey !

"Driving big boats doesn't give anyone knowledge of the intricacies of fluid flow dynamics"

Neither does running a calculator!But if you had ever spent anytime at sea you sure as hell would of felt your "fluid dynamics" under your feet.Not much of that with your feet under a desk I suppose!

Oh ! I did run a lil' 110' that did 21 knots was that considered fluid dynamics? [img]/images/graemlins/frown.gif[/img]
