A previous topic reflected on pulling in the tail of a fish (ala gunfish) to make it more ridable in larger waves.
Would shaping a vee bottom in each pin starting just before the fin achieve the same effect?
No that would give you a concave across the center, killing any rail hold by shaping V into the rails.
Shape the whole tail a V, with the spine at the stringer.
I have an old Lost fish that is similar to what you are making. It has single concave almost through the nose and then V starting just ahead of the fins. Works insane and once you put it in the barrel it just rides it on its own
all my fishes have had flat bottoms to a slight vee through the last 16 to 18 inches or so. this way the board is super fast but still has good control.
Ok, so this is a bonehead question, but has anyone put a deep-ish double concave in the tail of a quad fish? In my naive mind, this would leave a spine along the stringer, yet provide the lift/drive of the concave. I’m probably wrong, but what the hell. Any feedback?
My 5’11 Mandala canard quad has a single into deep double concave with a pronounced “spine” just as you envsion it…the board works very well…
The fish that I shape I vee from nose to tail gradually rolling it up from the center to the nose
Here is a picture of a fish that I just finished shaping. it going to be a twinzer. The bottom is veed nose to tail with double concave starting 6" behind center and a tail channel.
How wide is the tail dubstar? Is it one of the bumptail pulled in ones or the wide ‘traditional’ template? Do you think this spine helps rail to tail and do you think there is any loss of speed on small wave because of the concaves?
it is the straight fish outline, tip to tip swallow is fairly wide, although not as wide as my twin keel…rode it in small junky surf yesterday and I don’t think the concave slows it down at all, in any event, it was one of the only shortboards out actually gliding and maintaining speed…works great in w-oh clean surf regardless (duh)
here is the board (wide-angle lens distortion exists)
Anybody know what the bottom and rails look like on a Pavel “Speed dialer”?
Dubstar, nice looking board. what’s the dealieo with resin leash loop up so far on the deck? My foot hurts just looking at it…
Nah, take a look where the leading fins are and match that up with the leash loop…my rear foot is rarely, if ever, back that far. In fact, the board tends to bog if I try to put my foot too far back on top turns and off the lips, whereas it’s smooth if it stays a bit forward…
But I’m just the surfer, best to ask Manny the shaper for more info…

WOW Ben !!
… you sure like a challenge eh ?
would you do that configuration if you had to glass it yourself ?
How does that ride ?
…was that “bon bonzer” you did a similar bottom ? …what’s the feedback on how THAT bottom goes in different faces [eg : smooth , bumpy, howling offshore] , please ?
cheers !
ben
looking forward to testimonials on this fish. anyone, guys?
cheers,
The Pavel “Rainbow Fish” has a slight vee to flat to slight single out the back. But that’s a twin keeled retro fish. Rails are full on down rails, from the beak to the tail, where they become less boxy and more soft and rounded, but still hard at the bottom, with no edges whatsoever.
for a traditional twin fin/keel fish................stand-up that is..................
.........a perfectly flat bottom works best.
