I declared that a tri would win the R2AK. That a cat couldn’t beat a tri in short-tacking through the islands. And the kelp excluded the use of foils.
A elderly looking M32 daycat with foils won that race. I stand corrected.

Most of the boats that I have seen touted are so unfortunate, I wish I had kept the Geko a bit longer.  Typically she was about double the speed of an Fboat.     I’m sure some of these boats will show up at CSR this summer.

I keep seeing more earnest, helpless, odd entries to the R2AK race. People, if winning is of any interest, and from what I have seen, maybe it isn’t, you need something like this. A modern tri. And compared to the cookie cutter F-tris;  its much wider overall for the same length; it will stay more level, spilling less wind. Round bilge will tack faster. No struts to douche the crew in waves. This was designed for Simmo before he dialed back.  Add some oars and rock and roll.

An ama bow broke off during the race.  70′ trimaran? Clearly the only time we get to see inside.  Most of us.  Picture below.

Its time again for speculative forensics.   One would assume that if they going to spend a couple of million on it, everything would be perfectly engineered.  I learned long ago that just because they are famous or expensive, it doesn’t mean it was done right.

And again, I can only go off of what I can see here.  If anyone knows any of it first hand, let me know.

First it sure looks like a carbon fiber keel and a carbon fiber band running down each side just above the stringer.  Rule of mixtures error if so.  If you use carbon for global loads, there better be enough of it to do the whole job. Regulars here already know that the stretch to failure of carbon is around 1%.  The other fabrics have much more stretch.  So the carbon would have to fail before the other kinds would begin to help much.

I would not have used a stringer.  They increase the panel aspect ratio, which is weaker.  The closer to 1:1 a panel can be, the better.

That core looks really thin to me.  It looks like 12mm but am sure it couldn’t be that thin.  I would have had no less than 25 mm and maybe even 40mm thick.  I forget what colors of core denote what density.  Maybe someone has it handy.

Finally, that hull skin fabric sure looks like e-glass, or more likely Kevlar.  Dude.  That has already been covered.

They could have called me.

I see that the two most heavily media flogged boats, the Bieker proa and the little cat from Port Townsend have dropped out and never did well.

It really only looked like a very long Shaw Island Classic to me.  Agility would be far more important than speed as I see it.   The wind will be from 10 different directions in 10 minutes and you may have to tack 5 times in that ten minutes to dodge eddies or kelp beds.  And typically it all seems to be uphill.  Short tacking is often the rule.  In this kind of race I expect that the old 34′ Smoholla might have been quicker than the F40 Geko.  Imagine having to move the mast every tack as on the Bieker proa?  What were they thinking?

That says 30′  or so trimaran to me.  They tack faster than the cats.  You see it firsthand at races in the San Juans.  And with all the kelp I’m sure a foiler is off the menu most of the time.

And when there is no wind, I learned in the Tasmania race that you can move a small multi pretty well rowing.
