Actually considering to buy a selden gx 15 furler for our 100m2 symmetrical spinnaker. Providers told me "can not" but I think that if you look at a sail that normally flies, connected to the top end of the mast
AND held by 2 sheets
. A top down furling process will work going down wind
A sock is not a good option in hummid Singapore
. And as we have light winds all the time we need a solution. Pole-ing out is nbot as we have a crew of two and may be a few guests.
It puzzles us why a ATN tacker (attachment to the forestay for one of the spinnaker clews) would work, thus creating a luff. but ,...
but connecting the clew upwind to the adjustable tack would not?
I would consider to add two small lines to both clews or even a small cleat or hook or such on the adjustable tack so we can pull the sail on the upwind side and as such creating a luff close to the spinning center line.
In case nothing works? they do sell asymmetric
sales. But to be honest I give it a pretty good chance of working.
Our biggest problem is in fact to get the materials into Singapore
I will post if we get further, currently things seemed to have sold out in Europe
