Thanks for the feedback. Still undecided..

On another note, Cabrinha were great in sorting out a warranty claim on a wing. Really Freindly support and good Comms as I had to deal with them direct and not through the retailer. The shipping took a while but that was logistics and not their fault. Fair play Cabrinha!!!

The Shape Shack / Installing Chinook 16" boxes

« Last post by Velasco on March 20, 2023, 12:00:48 AM »

Anyone here installed these yet?  I normally use the Futures 10.75" boxes - but it would be nice to have the extra adjusting room for the foil.

I wondering what router bits you are using, if you made a jig (or two); or if Chinook has a kit (which I've looked for but can't find - next step is to call them).

Mahalo!

Reading the Maliko thread made me relive both the fun and the occasional terror. I guess that's what makes a sport addictive. I doubt I'll ever golf unless I figure out some way to scare the shit out of myself. Though one of the five or six times I golfed was on the Naval Base in Subic bay. There were Cobras on the course--that came fairly close to spooking the crap out of me. They look like big worms when they aren't threatening to kill you.

Boyum, Gregg Leion, and I did a race on the SS once where we were paddling towards dark clouds with thunder and occasional streaks of lightning. Just as the storm moved out a huge waterspout appeared right off Polo beach. We were headed to Makena.

And Boyum and I did one of those ill-advised Malikos where the entire north shore was lit up, with a 10+ foot North swell and East wind swells that had been building for 2K miles. We planned to come in at the oil tanks, but it was just impossible. We would have been shredded crossing the reef. Had to go in the harbor mouth and THAT was spooky enough--waves smashing on the breakwater with mountains of spray. Pier One looked like a big day at Waimea. And as we turned in I saw that huge Tiger that sometimes hung out there, but he wasn't on the bottom like he usually was. I probably could have touched him with both feet if I fell in. Wasn't going to happen, I was glued to the board like an Opihi. 

Apocalypto, dude.

Very cool. We don't have to worry so much about righting moment, though probably the folks performing at the pointy end of wingfoiling (like the Spenser brothers) may need help there. But I've always wanted to play around with curved or gullwing foils to tune roll stability. I don't think foil manufacturers will get too far into this though I know firsthand that Adrian Roper was screwing around with it long ago--he showed me a hacked-up prototype. That actually inspired the Fatboy foil I built which generated so much lift and drag that any other characteristics were masked. But it leads me back to our current 3D printing projects and makes most of the effort just changing a Fusion 360 drawing.

The complexity of the engineering work in designing these boats is just mind-boggling. I doubt that CFD modelling helps much at the extremes, which of course is where it counts. This video shows more of what it actually takes to make one of these boats work. The nose-high requirement is obvious--you really wouldn't want to bury the nose in these conditions.

LPB, So many great runs but a few that stand out as all time crazy.  One of those was a big Maliko (I can't remember if it was canoe or SUP) but there was a big swell running and I remember that we wanted to be way outside.  The wind got light and this foggy rain brought visibility down to zero.  We couldn't see each other a lot of the time and had no idea if we were too close.  As we approched the outer reef sections you could hear and feel the thunder.

Yeah, it should be a good summer in the Gorge. My dance card is filling up briskly, but there will be plenty of watertime. I look forward to seeing you guys.

Great times!  I wonder if any of our old SIC boards are still around.  I had a 15'6 that would be fun to take out for a spin again.  With our new foil prone paddle boards ready for their first run, it feels like Deja Vu all over again.
