Nice thread on displacement hulls but what are they? please explain.
Nice thread on displacement hulls but what are they? please explain. It
s worth the time to carefully read and study Greg Liddle
s website: http://www.liddlesurfboards.com/intro.html Displacement hulls incorporate a sophisticated blend of flatter and rounder bottom design elements, that offer a balance of speed and control by means of both planing and displacement. Well-engineered hulls are deceptively MORE than the sum of their parts… the fin(s), rocker/foil, template, overall weight and flex, rail contours, etc. all work in harmony to drive the board across long, unwinding walls… sort of a “zen” approach to wave riding: maximum performance is achieved through minimum effort… smooth, very fast and clean, beautifully addictive sensations.

Nice thread on displacement hulls but what are they? please explain. I assume you can’t turn them like a thruster but can you get them to turn tight if needed?
I assume you can’t turn them like a thruster but can you get them to turn > tight if needed? Not from the middle of a Liddle…you have to slide your back foot back and pivot turn which causes to tail to slide out, kinda like a hocky stop on a ski. You can turn but you lose the acceleration feature of the rail turn. Greg can give you runners on the rail of the tail that keep the sliding to a minimum but the sharp turn is still a decelerating, pivoty thing.
I assume you can’t turn them like a thruster but can you get them to turn > tight if needed? you can but the tendency is to stay on that track.you can hit the lip, but you’re not going to get as vertical, and recover or switch directions as tightly as a thruster.
Matt: Has Paul ever built a hull with a twin fin set-up; no toe-in, keel-like fins? Maybe that would allow shorter radius turns without losing the rail turn feel. Newbs

Matt
I was thinking a Liddle point break outline or 'tweener with 1/2 to 1 inch wider tail. I’m embarassed to say I don’t know what Paul’s outlines are like. Similar to Greg’s? Any pictures of Paul’s stuff on the web? Newbs
It would be like riding a downhill snowboard in a half pipe. Yeah you can do it but…>>> you can but the tendency is to stay on that track.you can hit the lip, but > you’re not going to get as vertical, and recover or switch directions as > tightly as a thruster.
Matt are you teaching this stuff to your class?
There’s a classic photo of Michael Peterson (bottom pg 121 “History of Surfing”) that shows him performing a beautiful cutback reminiscent of any hot rider today on a thruster. You can clearly see the full outline and hull bottom on his board.
Matt are you teaching this stuff to your class? yes! I thought I told you to stay in the corner and to not speak until I say you can.Bad,bad boy…

Any pictures of Paul’s stuff on the web? i think Steve K. had a couple.how they surf i don’t know.Yes, Paul’s boards have very similar outlines, in some cases the exact same, as Greg’s.to the uninitiated they look like identical twins but there are, in general, minute differences.>>> Newbs
