Idea??

was curious to see what everyone thinks about doing a small concave that goes into belly channels. since gowing wider to a more narrower space speeds things up, would that work??? whats your insight on this???

Never ridden a board like that but it seems plausible and functional though depending on plane shape and fin setup it could dip into the realm of tracky and stiff. Give it an experiment, though i’d try to keep the entry concave very subtle.>>> was curious to see what everyone thinks about doing a small concave that > goes into belly channels. since gowing wider to a more narrower space > speeds things up, would that work??? whats your insight on this???

Concaves and channels tend to have a minimal effect on a boards performance – not just from my experiences, but many long time shapers have told me the same thing. It is fun to experiment, remember – concaves and especially channels are a bitch to glass and sand. Maybe that’s way guys who do this for a living are sometimes soft on the idea of putting them in. I can say that my best riding boards have been those fairly mainstream in design. I got physchodelic on a few boards and they had problems on the water. “find the middle of the road, and take it.” – not my words, as many of you know. Shine http://users.leading.net/~shine

I don’t know, Shine…I’ve ridden a mike eaton bonzer (with double concave venturi back, and concave under the nose) and this board’s concaves had a PROFOUND effect in hollow, reefy waves - compared with a typical, short “longboard” (I like his eight/split with rounded pin). You can actually feel the thing aquaplane in big, clean and hollow-er surf. I love the damned thing and have copied it for myself (shhhh…). It WAS rougher to glass than a “regular” board (didn’t ride as nice as mike’s), though …but well worth the time. Don’t give up on the concept, altogether…check one out! T.

A standard short board setup that works well is to start your concave about 1/3 of the board length from the nose. Start your planer at 0 and gradually open the depth adjustment to max out at about 1/8" at the front fins. A pass down the center will do,with a couple of passes to either side. At this point blend to a double concave (subtle, 1/8" max)through the fins (you can do this with a single short pass on either side of the stringer) and then fade out to flat (no concave) at the front of the back fin. Finish with flat or a slight vee (for bigger wave boards). Blend your planer cuts with 40/80/screen on a foam backed block. Make sure you don’t destroy your rail rocker line in the process by over sanding the area. Keeping every thing subtle is the key to an all around board. More radical setups (channels)tend to work well in very specific conditions (glassy, hollow, no chop, etc.) which is fine if you are going to have a large quiver, but not so good if you only have a couple of boards.
