I have noticed that the CM construction manual had the stem unit pictures fall away and I did not notice it when I had Pagemaker open.
I will insert soon, but meanwhile here are a couple of good pictures of a stem unit from builder John Stames. He has sent also a raft of other great pictures that I will sort as soon as I get out from under the deadlines.
Brian left the snow country. Sorry but only on Face for now.

Clearly I am not intervening quickly enough to prevent this kind of mistake. It’s a Fontaine-Pajot Maryland 37 Trawler. It is intended for displacement speeds. Top speed is reported to be 15 knots with 140 HP per side. It is not only dragging transom, but a huge transom. I don’t know but it sure looks like a cat designed by single hull designers. Even a heavy powercat of the same size but correct hulls should do 20 knots with about 80 hp per side. I tried to make an intervention, but clearly am not famous enough.
As an update to my recent rant against forward cockpits( http://multihullblog.com/2014/12/forward-cockpit-2/), I find this.
Peter Johnstone “Fyi we advanced beyond the forward cockpit to something much better on the Gunboat 55….”
First run at a new 48 cruising cat using the Outsider 48 connectives. Flared hulls.
I almost forgot about this short video of Leila at Holo Holo Charters. The hulls were built rapid construction using a CM developed plywood female mold. In those days we surfaced the mold with epoxy and that presented some work finishing it. Now I would squirt it with Hi-Build only. Then wax and PVA. Quick and wonderful shape.
Once again video only lives on Face. https://www.facebook.com/video.php?v=953417014686587
I have to add one more. They have such nice pictures. USCG certified for 49 passengers.
Anton was wondering about NY Cell PVC foam. Numbers seem to be similar to divinycel but I have no experience with it. Price is said to be much better. Has anyone here used it? There is this link but it is not terribly useful. http://www.pvc-core.com/
and for comparison
I was asked to update the design of the 149′ trimaran ferry, but there is no funds for design yet. X bows now for smoother ride.
Maybe I knew or not, but here is the link for the KHSD 37 built in Brazil. http://www.aladin30.com.br/photo_cat_netuno_388.php
I wish it didn’t have the fin keel and it seems to have some trim issues. Almost every plan has a weight/trim spreadsheet that the build is supposed to keep updating with.
