65 Charter Cats Front View

I got that great opportunity to see my Alii Nui side by side with a Constant Camber 65 last week. It was great to see the differences. Again, both were built by the same yard. Alii Nui is foam/glass and the CC 65 is constant camber. Except for butting all the plywood sheets instead of scarphs, and bagging the ply to a true mold, instead of itself, this boat’s hulls  were built exactly like the CM system that I have been using for 30 years and that CC has been criticizing for almost as long.  Cool.  Oriented ply sheets.  Stringers instead of mass. Thinner hull skin.  Cool.

Alii Nui is 36′ wide.  I cannot find the CC 65 data online, but I’m guessing it is 30′ or even 32′ wide. That makes a smaller playpen.  First the Alii Nui.  Both from the same distance on the dock.



Sailing On Alii Nui

Last week I got to take a great snorkel trip with Capt. Timothy on the 65′ x 36′ KHSD Alii Nui.  It runs out of Maalaea Harbor on Maui.

It was a nice comparison to come back to the harbor and tie up right beside a Constant Camber 65 daycharter cat.  Both were built by Schooner Creek out of Portland, OR.




Dragonfly (the 63) Missing a Mast

“Stickless in Hawaii: Dragonfly was dismasted 400 miles south of Hawaii. The best we can determine is that a wave, significantly bigger than the others, broke beside us throwing us sideways toward the wind causing the mast to break because of the inertia of the mast and the force of the wind on the sail. The shrouds and headstays were still intact and we made an assessment that trying to save anything from the rig posed too great a risk to the crew considering the conditions of wind and waves, and the absence of safety lines which had been pulled over with the rigging. Al and Stephan cut loose the shrouds and control lines and let the mast go. Fortunately no one was hurt and we were able to make it to Hawaii 6 days later with 10 gallons of fuel to spare. Significant credit goes to the terrific crew for getting through this incredible event!”

It sounds like a shear failure or maybe too large a cutaway for some hardware?  I’m trying to get a picture of the buckle before the mast was pushed overboard.


Out Next Week

I will be in Hawaii this 17th through 27th. Anyone has anything I should see there, let me know.
I will have the workstation with me and most of the study plans, if anyone orders some.
it should also be a good chance to catch up on 3D modeling and drafting with no calls nor other interruptions.

Houseboat Hulls

Last week I got to visit the boatyard of Thain Boats, the builders of the Uganda ferry cats. They are finishing up a SIP panel houseboat with a variation on some hulls that I designed a while ago.  Albert, the lead, intends to stack them in the future and stick the internals in with Plexus on the site.  These are so much better than the alloy ones that the developer used to require.

Solid knitted glass laminate.  No core, hence all the frames.



Catamaran Grounded

I don’t know yet what design, but I have always said that a catamaran with keels is the worst possible craft to run aground in.


On a mono, the crew can kedge off of the top of the mast. I’ve been there. On a tri, the slackers can all be ordered onto the ama.

A cat with keels is a whole difference scenario, and better hope that you don’t get neaped.   A cat with boards can stop, determine the way back out, lift the boards, and flee back.  Keels don’t allow that.  Thats part of why I prefer boards, among all the other reasons from pointing better to being able to perform repairs while underway.
