Got a rendering of my 40 daycharter cat built in China. It was based on the F40 performance cat built by Mystere a decade ago. In the new economy, the customers take my 3D model and have a kid create the rendering at minimal cost.

I spotted these great examples of composite hardware foundations on the Hall Spar at CSR. The boat is a Baltic 77. One is a boom base and the other is a vang base. Flipped upside down the vang base is how I see the best hound bases on multi now.

Boom first

and vang

Finally video. It is only on Facebook so you have to see it from there I guess.

I just picked up the box of reprinted CM Construcion Manual on DVDs. I will be shipping out to everybody who ordered them.

While at CSR today I saw this new Bieker anti-cavitating rudder. I was told that it helped a big Perry boat, Icon I think it was, a lot. Not sure how it works. Would mean rudders must be CNC if it is a thing. I don’t know if it only works on monos or at what speed it works best. Would real fences work better? I only found this online. http://www.biekerboats.com/Bieker_Boats/Rudder_Tubercles.html

Was 36 years ago this week that I launched my first trimaran. Was my home for a couple of years.

I heard it held the Point Hudson Race record time for several years. I remember the race officials asking if we could prove we rounded the mark. We could. It was still daylight when we crossed finish line back in Seattle.

I just got a picture of one of my 40′ foam/glass flared hull cats. This is the one built by Kenny in Port Townsend.  I recall that it was built around 1994. It is a design for upper latitudes sailing, not tropics. It has a bit more “in” than “out”.  Inside and  outside helm stations.  Nowdays it could be 90% built with a flat bagging table.

A couple more shots of the 4m catamaran oceanography drone. These are renderings by Nic at the company building them. Next ones  might be composite.

James is sailing now.  And sent this nice note.   Now he will know where to put the leather bits on the batten sleeves.

“Kurt just wanted to say that you designed an incredible boat. It’s everything I ever dreamed of and everything just works the way it is supposed to. I’m pointing up higher than I thought a sailboat could go. Thanks for all the help and time on the phone! Your the best!”

I see over at Steamradio that while I was gone, some guys were having a religious experience building a 42′ KSS hull in 4 days with a half dozen people. I watched the guys at Sea Island Boatworks build Peter Cromwell’s 56′ first hull in 4 hours. Plus assuming a half day bagging each of the two panels.  Add another half day for adding sheer timbers.  But still not 4 days total.   And they were joined, not just proximate like the KSS pictures show.  And no religion involved.  And when he was pissed, Keith did the 40′ main hull in the DVD again in less than 3 hours.  Still no religion.  Pic shows the hull spread.  It will be pulled back in when keel is cured.

While on the trip I did work out an improvement to a composite rapid build that I published in early 90s, using CM hull for a female mold.  I built the Geko amas that way and Kevin in Kauai did a couple of cats that way.  I sorted out much faster steps.  I have to squirt 2 part poly on the spaceship before I have time to model and publish it.
