Ahoy dere, Ebb -

Thanks for letting me see what to clarify!

The tabernacle material is aluminum (the type used in making those really tall tuna towers for sport fisherman), and tho' I didn't make it clear, the hinge/pivot will be above the diagonals, somewhere between 14-18" off the deck, and I intend for the mast to lower towards the stern.

That's the reason for the height - eventually Katie will sport some kind of dodger, so I was going for as much clearance as possible while hoping to keep it looking no too ungainly.
