    That's the idea behind it.

    I mentioned in the Coil thread that a buddy of mine just got a new board from them with what they called "the new technology"--dimpled bottom. Can't wait to ride it.

    As far as 3DFins, word has it Kerrzy actually ponied down some serious financing to get the company off the ground, seeing as how they are from his old stomping grounds in Margret River and all. I'm really excited to see some more advanced experimentation going on.

    Did he actually say dimpled bottom, or just new technology? THE place to find Coil info is on the Swaylocks Coil Ride Reports forum, and there's been no mention of it...

    Hahahaha! Some of you may be old enough to remember that dimple-bottomed boards have been tried before... in the late 80s!! (with less than stellar results)

    The problem is that the same principle of lift that applies to golf balls does not translate directly to planing surfaces. If this were the case, you could be sure that ship and boat builders would already be designing all of our vessels with dimpled bottoms.

    Thinking about fins similarly, one would think that this design would've already popped up in other applications. It still seems to me that foil is more critical to the lift/drag ratio. Nevertheless, more power to these guys. I'm always in favor of folks trying to find ways to advance our sport. On the flip side, it'd be a shame for a company to take advantage of folks lack of knowledge, intending to make their money selling a "gimmick" that in no way advances our craft.

    It'd be great if someone affiliated with 3Dfins could post with more explanation of how they think the dimples are helping. Same with anyone proposing to bring back dimple-bottomed boards.

    Merry Christmas Dudes!

    Anyone remember "speed spray" from the late 1980s early 1990s?....same principle. Spray applicant that went on the bottom of your board and give it a textured surface that supposedly broke up the laminar flow right along the surface for more speed. AND could easily be removed after you realized it made no difference, unlike the dimples that also got a little play back then.

    Alas, I see you have gone directly to the source with your question! I can't wait to see what Mike has to say. Did you go back and read the archived threads about folks shaping them into their boards in the late 80's/early 90's? Let's just say the dimples pictured in some of those photos are rather.... eh.... large.

    Heck, maybe if Hatty can quit shadowing us from these NE'ers you all seem to be enjoying (last result was barely waist high here with 30 mph offshores) I'll be able to get a more intimate relationship with the board.

    Oh yeah, Merry Christmas everyone. I hope some of you get some good Christmas barrels and post some pics and vid 'cause it won't be happening down my way!

    I concur.....Wouldn't dimples on a planning surface catch water, making bubbles which would in turn cause drag???

    The 3dfins site explains it "in a nutshell" and you can search Swaylocks to find many discussions on it.

    Bottom line, I'm going to get those fins soon.
