Hi,
I went to Rob Denny's house in Swanbourne yesterday and looked and talked. He does well without a proper shed, though the double garage is pretty good.
Elementarry stuff I liked were the newest version of the rudder(single on a slide from one end to the other), that kicks up if hit, this is good engineering, because you can't raise the rudder up, like to see how it works on the water.
I liked the wing mast made from a single peice of this honeycombed stuff of plastic I thimk it is the polycore at $20 a sqm (6mm thick size).
Hinging for me is best by leaving the mast as usual with a bit more space at the bottom and making a tabernacle if you can call it that up over the bottom stem. This should include a removable 4th side and 3 permanent sides so you can let the mast swing down when you take the 4th side off. Seemed pactical enough with carbon and squaring the
stem to fit the tabernacle sides.

Should be possible. Have to offset the masts slightly so they don't
interfere with each other as they lean towards the centre of the lw
hull.For going under bridges, you wouldn't have to remove the masts
but simply leave them tilted,
