Re: yucca fins

Its been a couple of years since this thread was started...any new reviews of the Yucca Standard Flex? DuckFeet have been my goto fins for nearly 40yr, due to their stiffness and resulting thrust. But, there has always been a certain amount of pain that goes with wearing them. Primarily that has bee...

Re: Monolith 2001: XLPE

Very interesting experimentation...the foam you're working with is difficult to shape, not just because of the flex but also the cell structure. With polyurethane foam, a chemical reactions creates the foam in an enclosed space (mold) and the cells share cell walls, so its more or less a single, sol...

Re: First Build

Actually, very similar to the planing hulls Lindsay Lord used for his research, including the exit concave to reduce pressure/drag in the rear third of the bottom.

Re: First Build

Nicely done...very traditional. You gotta use the tools that work. Shouldn't have any trouble with speed, with flat rocker and parallel rails. Might be a little stiff when turning. You'll need to learn to heavily weigh the tail when turning to bring that rail-line up and out of the water. Like ridin...

Re: First Build

My prone boards weigh about 2.5kg, so even a 5kg prone board seems too heavy. Without getting into the whole buoyancy vs. mass thing, I've found that better buoyancy = better performance. But, you gotta use the materials available I guess. I would think 1/2" or 5/8" marine plywood would be...

Re: New project... this time a Paipo

I agree with #29. The TA Bonzer has 19deg cant built in to the base. Cant increases lift but decreases hold. Typical Bonzer set up has a 6.5” center fin to counter drift. Your challenge will be installing removable fin boxes in such a thin hull. Removable because knocking off and re-installing glass...

Re: New project... this time a Paipo

Also keep in mind interaction between rocker and fin toe-in. Flat rocker resists turning more than curve-y rocker. Flat rocker plus no toe-in = max speed, but very stiff handling. Lots of rocker plus lots of toe-in is very responsive, but needs to be constantly turned (up and down wave face) to main...

Re: New project... this time a Paipo

Use symmetrical foil if no cant or toe-in. Much better hydrodynamics. Asymmetrical foil benefits toe-in. Toe-in benefits turning. Use 0" toe + sym foil for max speed, 1/4" toe +asym foil for max turning, 1/8" toe + asym toe for in between. On quads, 1/4" toe in front and 1/8"...

Re: New project... this time a Paipo

I like the outline with WP slightly back. All the curve in the outline should help compensate for the flat-ish rocker vis-a-vis turning. Aspect ratio (L:W) looks really good. Once in a good wave, that thing should fly. Question in my mind is whether or not ultra-thin rail will hold a high-line witho...

Re: TBG7

Summer doldrums are putting a kink in my R&D plans. I've got another twin fin set to try out. Too early to start thinking about a Fall Paipo Gathering?

Re: TBG7

Interesting thought...although airplane prop speeds are much greater. I really don't understand the science behind either. The basic fin template has roots that go all the way back to the Dewey Weber "Hatchet".

Re: TBG7

I've been using FCS Fusion and more recently FCS II boxes for over 10yrs, with all types of boards and fin templates, and I've never had a fin box or a fin tab failure due to a surfing maneuver. I've seen fin boxes of all types' e.g. Bahne, Futures and FCS dislodged following collisions with rocks, ...

Re: TBG7

Eureka! moment...I bought a set of fins for my new but still-being-glassed kneeboard, and on a lark I installed them on my G7. WOW! The improvement in performance rivals my quad G-5. The fin template is the Wayne Rich Nightmare Twin by True Ames fins. Wayne is a shaper's shaper, having won the prest...

Re: TBG7

Caught a solid combo swell Mother’s Day Weekend in San Diego. Clean conditions in the AM on both days, sand-filled reef point with 3’-4’ faces on Friday, bumping up to 6’-7’ faces on Saturday. I surfed the G7 Twin on Fri with 4.6” fins (TA Side-Bites) and 5.1” fins on Sat (TA Twin). The G7 Twin with...
