Greetings all, Roger is quite right about the load on the cabin and a compression post had to be added to the boat pictured with the 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.
