Hi Guys, I collected the photos from another board I made this fall - I think this is board 3. I had a Mabile 9’6 Twinzer longfish that I really loved, and my neighbor set me up with a 10’8 Y blank. I’d wondered how the board would work at my local beachbreak with a bit more rocker, so I went at it with that in mind.
I stretched the template at the widepoint, and the shape stretched to 10’4 before the arc started to look wrong, so I stopped there.
I kept the fin cant, toe, and placement from the tail the same as the 9’6, figuring that board was also so long that the placement would work, and being a rookie a twinzer would be challenging enough without messing with it.
I was really worried about glassing the fins on, so when the cloth stuck to the tacked on fins during mockup, I left it in place and painted the resin on rather than laying wet glass on the fins. I know it was “wrong” but I really didnt trust my ability to get everything placed right if it was already wet.
i went slow on the buttcrack, and tried to really carefully prepare my patches for that area. My first fish was a disaster getting that all clean, so I wanted to go slow and leave myself as little to fix as possible.
in the end, the board turned out to ride well! I got some photos of my friend getting some excellent rides on it, although he’s one of those surfers who can make any board look good
Great looking board! You did a nice job on rolling the entry belly. Boosting the rocker appears to have been a good idea. Any numbers on that? I’d be curious to know nose, widepoint, tail and tip-to-tip (swallow tail) dimensions!
Hi guys, thank you for all the comments - I had to get to my 10 points to respond, so I apologize for the delay. I went and measured the fin layout and missed the rocker and template measurement question, so I’ll add that soon as well. My neighbor bought the board from me so I have to run over and get the numbers. I thought I’d written them all down, but I can’t find the folder of dimensions I had to save my life
Twinzer Fin Setup Placement:
Trailers:
Rear of Fin 12" from tips
Rear of Fin 1.5" from rail
4 degrees cant
1/4" toe
Canards:
Rear of Canard 1 1/4" off Trailer fin pencil line
Rear of Canard 15 5/8 from tail (1 1/8" overlap with main trailer fin)
1/4" toe (shorter base makes the toe in steeper than the trailer)
6 degrees cant
These measurements are from my board, modeled off a 9’6" Mabile Twinzer fish with very little rocker, so I assume it’s on the loose side of a Twinzer layout. I figured, making a 10’4, that once we were out to those huge lengths the 9’6 setup was close enough for my purposes. I did sort of err on the side of looser, given the length of the rail on this board, and I tried to let the fiberglass halo stand a little tall on the height side as well, just to get a little more fin in the water without adding more base.
I’ll get the template measurements next time I can get that board in my garage - I’m building a little woodworker setup in there using all old belt driven 40’s tools so I can make better wood keels and D fins, so once that’s a workshop and not just a pile of junk craigslist metal on my floor, I should be back in business
