This is a board that has been some years in development. It all started with a conversation I had with Bill Thrailkill where we were discussing his twin singlefin placement and I proposed making a modified quad. It sounded like a great idea at the time but after really thinking it out I realized that the only way to get the fins close enough together would be to have four glass-ons and four removeable fins (the glass-ons are glassed over the boxes), In order to do this all of the fins would have to be hand made to match their counterpart.
The outline chosen for the board has a nice wide tail to accomodate all the fins. There is a lot of vee in the tail to allow the board to get on rail in tight turns but the rest of the bottom is flat for speed. So far the feedback of riders is very positive with the fins in the current positioning as the photos.
I am open to allowing the board out for demo if you are in the San Diego area.
Thanks Huck. Closed shop in L.A. and moved to San Diego. I have had this board out twice myself and found it very fast when surfing off the fins but to get a better feel for the difference I need to surf it with all eight and with four of the fins out on the same day.
Mahana- Hows that surf stand work? Those cross members at the bottom with the adjustable feet dont seem very wide. does it get wobbbly when yoour spreding resin or sanding? My stands have agriculture disc’s(~2’ dia.) & & I still have some “wobbling” if I’m bearin into it.
Parthenon- The base is the one they sell thru Foam-EZ snd they are suprisingly stable at least for shaping and sanding (I have different racks for glassing). I prefered the racks more when they where mounted to the floor but these were an extra set when we closed our other shaping room. If the feet were any wider you would trip on them while planing. The down side is that if they did move while shaping you must check level before continuing, to alleviate this problem I would put two 30lb sandbags on the beam.
All of the fins are single foil because a decision had to be made and we put the glass-ons in our proven quad positions just in case it did not work in the eight fin configuration. There are still other combinations we have yet to try by moving these fins around.
Single foiled, or double foiled, work well in my twin configuration. Me, I prefer the single foiled fins, with the flat side toward the rail. Most others do too.
Bill,
Do you think the flat side of a canard fin should face out in a twinzer configuration, too? Similar effect with the main twin, but the fins are offset and not parallel.
I would certainly explore that configuration. While I’ve not ever done a twinzer, I do know that fin size, and proximity of the canard, is crucial to optimum performance.
If you are referring to my twin setup, I use two full size fins, in whatever size I would use as single. In a canard situation, I like the canard to be in the 25% to 35% of the main fin height, with a much higher aspect ratio and camber. But, that’s just me.
