Thanks for the lead. From the website:
'When you take down the gennaker you just head downwind and pull the retrieve line and the whole thing is rolled into the gennaker launcher. It also tightens the sheets so they don't drag in the water while going upwind'
Anyone who's used this, Does the retreival line somehow also roll it up, or do you use some sort of crank on the side of it?
Enquiring minds want to know.
Kinda cool how it does like like a turbocharger hood scoop, since the headsail is kinda like a turbocharger.
