For those looking to see the hatch launch in action:
don't know which J30 this is at Key West ... but it pretty much sums up the program. Genny snugged in a bit, fordeck helping the release out of the hatch, halyard raised at the mast, guy prefed to end of pole, probably sheet prefed to just behind shroud.
on Vee Jay because we have roller furling ... the foredeck rolls in the genny from his position just before the mast as soon as the spin is up and pole brought back. The Genny lazy sheet is over the front end of the top bridle, and the crew is trained to maintain a genny sheet on the front end of the pole for jibes.
I was having crew problems with cockpit confusion about pole up, pole down, pole forward, pole back ... so moved spin halyard to mast, pole lift to mast and genny furl to foredeck. only thing we control from back of boat is pole down. But as I remember from the old days the first thing we did is always set up a spin halyard cleat on the mast... still goes to the turning block at base of mast just in case.
