[Rhodes22-list] Head ventilation

[Mary Lou Troy]

Just a note here that there are a number of different configurations of 
R22s. I believe that most were built with a compression post. On ours it 
was built into the structure of the semi-enclosed head. When we bought 
the boat (a 1991) to be refurbished in 1998 it did not have overhead 
hatches so we asked Stan about putting a single hatch over the head 
area. He said there was no structural problem doing it so that is what 
we had done.

>> Unfortunately, we don’t have Stan available anymore to ask.  I would like to ask him if he did anything to reinforce the cabin roof when GBI implemented those 2 opening hatches.  Those 2 hatches together represent a lot of cabin roof structure removed around the area loaded by the mast.  Was the cabin roof so over designed initially; that, 2 big holes can be cut into it without compromising the structure?  If Stan had to reinforce the cabin roof with something like C fiber; then, he never mentioned it in any advertisement that I saw.  I wish there was someone to ask re this issue because my “calibrated engineer’s eye” says “too weak”.  Scott, I advise you to proceed cautiously, because the cabin roof would be hard to fix if you weaken it too much.
