I’m back from working on ferry cats in Belize. I’ll get that trip on here as soon as I get the pictures downloaded.
It’s almost January. No more trips planned. As Lewis and Clark might have said, but never actually did, “January has nothing to recommend it”.
So I will recluse myself the coming month and devote it to the new designs.
I have a new 38 tri, a new 35 tri, a new update to the 23 tri, continuing on a new 62 cat trawler, and if time allows,  finishing the new 27 cat and more on the new 45 cat. Busy month.

Broken Board

 And does anyone have board molds and would like to build one or two for a 56′ cat?

OK, here are the pictures and hypothesis.   The owner reports that he didn’t hit anything and the crash block was not crashed.  Further, the balsa core was not soft nor rotted.  The laminate was triaxial, as was designed.  He thought there was a buckle on one side.

Notice that the balsa is at the faces, but there is foam in the middle.  It looks like Airex or divinycel.  Both in 100 kg density or less have much less shear and compression strength than balsa has.  Recall that the highest shear load in a beam is at the centroid, as is the lowest bending load.  Enough side load could move some of the rigid balsa into and crushing the much weaker foam.  The core is there for shear transfer between the faces.  Look how thin some of the foam layers look.  Crushed.   It looks like the weakest link failed, to me.




Email Problems Update

It turned out that the problem is both intermittent and is with my cell carrier, Verizon.  My office email is also on Verizon, with a plug in cell modem.  This could take a while.  If you have an email bounce, if you could forward to me for forensics, when it is back up.
I have been using my laptop with Squirrelmail while travelling. But that unit has recently started sending email with reply of, which is incorrect. One more thing to sort out. I’m on the road this week so if you could replace the “same” with “khughes” for this week.

Kolea is Famous

My 36′ daycharter cat in a box will be on tv this Sunday.  Owner Eric notes “Paradise Sailing Hawaii, will be on a show called “Hawaii Life” this Sunday, Dec 11, on HGTV. According to the HGTV web site it airs at 8:30PM.
The name of the episode is: From Cold Aspen to Sunny Big Island. <>
The TV crew was on board filming for 2 hours. They even hired a chase boat to get shots of us under sail in the sunset.
The show, however, is only 21 minutes long…. we are anxious to see how much time we actually get.”
