Looks good.  I'd lay out the ww hull panels differently, so that the joins were in the flat areas, not the bent ones.  Then the bent ones can be solid glass, so no filling, coving or taping is needed. Maybe also make the lee hull sides less flared so there is room for the mast step and to help it resist twisting.  39' 11" rather than 38', unless there is a reason not to.

The rudders on the stub beams should work as that location has been tried before.  I would not make them any smaller on the basis of having a leeboard as the time the full area is needed most is just after a shunt, when the lee board is likely to be stalled.  I think.  Rudolph's experience and experiments have put all my former ideas on leeboards on hold.

A telescoping mast is one option, but will be pretty hard work to raise as it will weigh over 100 pounds.  Easy enough with an electric winch or winch handle.  Schooner rig is another easy option and a two piece, non telescoping mast a third.

The ACC guys would be very keen to build it.  They are far more precise than I am, would take a bit longer, but would make a better job of it.  The extra time would be more than compensated for by the time saving ideas we have already come up with.  They could also build you the panels for you to assemble.  

regards,
Rob

Hi,

I have been watching the rudder discussions with great interest, and
Rob's Solitarry build with absolute fascination. Putting these things
together, along with some new thoughts on how to break down a boat to
fit in a container has made me rework the files in "Gardners
layouts/Solo". Look at solo38_front, side and top.

I moved the rudders to stub beams so they are further apart, so can
hopefully be smaller. I have not drawn in a leeboard, but I am still
thinking about it.

In terms of containerizability, it occurred to me that I could build
each hull, then build a 7.5 foot wide cockpit. The top view shows how
they lay out into a shipping container.

I am not that happy with the lack of sail area. I am drawing it with a
collapsable main, like Solitarry but the most sail area I can get is
about 400 sq ft. I think this design will be about the same weight as
a harry, but it has slightly less sail are. I am not sure how to
increase that and still fit the mast into a 40' container, other than
Rob's extendable mast. Suggestions are welcome.

Question for Rob: since this can fit in a container, it becomes
possible to have it built overseas. Is the guy who is working on yours
considering building other harrys in the future? I might be
interested.
