Re: Mast tabernacle project

In the case of those screen shots, the cabin profile pretty much negated an 'aft' drop without a hugely cumbersome tabernacle. The advantage I can see, though, is that the boom is a longer lever and more robust connection than any gin pole or spinn pole might be used to support an aft drop.

The other complication to this (and any system relying on athwartship support) is that ideally the center of rotation for both the mast pin and the supporting rigging ("A" in the diagram above) should be in line. Does he have shrouds attached to rigid 'tall' chainplates? or is he using the stanchion as a temporary one? it's not clear on the sketch.

Anyhow mechanically it should work... I just like the idea of being able to catch the rig in the cockpit rather than forward... Hope it all goes well, can certainly see the desire to avoid annual crane rentals and delays.
