I feel privileged to be in receipt of a message from the Oracle of Rhodes. ; - ) as well as the elders of Rhodes like Rummy. I cannot argue with your immovable object argument. Something has to give. Through bolting and reinforcing the surrounding area of the cabin top, as we have done, might raise the threshold level for dismasting. Your point is that at some level of (leverage) force through bolting can result in costly damage to the structure. We agree. You also point out that the pivoting hinge would allow the mast to come down in any direction without becoming disconnected from the cabin top or disconnecting with little damage. That's a really good point. By the way, pivoting and single screw attachment is news and I don't think anyone mentioned that detail. Our fixture has three screw/bolt holes.
In other words, it seems that the design anticipates a high level of risk of rig failure. However, under sail, a prudent sailor has numerous options for managing rig stress including dropping the sails and running to the nearest safe harbor. Inspection of rig tuning avoids surprise rig failure under typical sailing conditions. The one non sailing risk is DIY mast raising without extra helpers. So, we surmised that some of the argument for your design, and objection to through bolting, anticipates more incidence of mast raising mishaps. As you say, with 9 stays versus the typical 6 as on my Abbott 22, a dismasting under sail should be almost impossible for the average day sailor. So, you will be relieved to know that we will replace the bolts with screws and attach a copy of your email to the mast in the event we are someday found under it ; - ).
