ebb thanks for the feedback. I'm always interested to hear what you have to say.
So the bottoms were curved also. That explains a lot about the dimensions.
ebb, you may have missed that my whole reason for doing the mast beam is to eliminate the compression post. The unsupported portion of the beam in the center will actually be less than 2 foot wide when my mod is complete.
BTW the Precison line of sailboats made here in Florida are current production models with mast support beams that are made with plywood laminated together and then glassed to the bottom side of the deck. They have only a small portion of the beams ends supported by a plywood bulkhead that is just screwed to the beam. You can see it a little bit in the picture of my old Precision 18.

A man can succeed at almost anything for which he has unlimited enthusiam.
Sorry Jerry,
assume is the mother of all foul ups.
The key still is we can have nothing move under the mast.
And each of us has our own unique solution it seems when we stray from the box.
I love the sweet lines of the Commander.
The curve of the cabin roof is particularly pleasing.
Maybe, maybe it's possible to design a kind of 'break water across the cabin under the mast.
Have the beam outside.
If it wasn't a breakwater but a rounded slope sided and gel-coated mound it might just disappear and not mess with the lines.
In discussing sailing Ariel Spirt, one of the possibilities was the idea of sailing her to Puerto Rico. As I considered what I would want to do before undertaking such a journey, the thing that came to mind first was to address the strong back.
I like the idea of the stainless plate sandwich, but getting the stainless bar and having it polished before getting underway was not going to work. I like the earlier post about using large aluminum angle, but hate hitting my head on the doorframe.
Add to that Ariel Spirit has the original bright work trim around the door, which I would not want to mess with that.
Used 5, 5/16" stainless carriage bolts with the smooth sides and stainless fender washers on the cabin side. Not a bad look, and very strong.
I like the angle because the extra angle will prevent the bar from trying to twist. The difference in what I did was that I put the "extra" bit on top. I a very pleased with the way it came out, will post a couple pictures later.
Just learned the person in NC that was buying the boat is going in another direction, so I am getting underway in a bit to sail the ~140 nm across the big bend... Glad to have addressed this before heading off shore.
