How tight should it be?
And should it be the same at the top as the bottom Mast pockets is what I'm talking about. When I knocked together the sail for 'Test Bed' I just took the max spec size from the Class 5 regs which I think was 140mm flat. I've just spotted an article explaining windsurf downhaul about the bottom of the sail being the 'engine' and the top the 'exhaust'. And that the bottom needs the battens close to the mast to get the correct shape but away from the mast at the top. Is this correct? Should I tighten the pocket to be close to the mast (not too tight to stop easy movement) then run the stitching straight along the pocket or should I follow the mast's taper Thoughts from the experts please, as currently the sail is like an on off switch, literally nothing happens till the wind picks up then it's off like a rocket

It lives!!!! (After a fashion).



Struggling in a 8mph wind, but moving. A lot of lessons learned as well.
1) Never mount your blocks off the seat floor as your leg/thigh can only take a certain amount of squashing. Blocks now lifted 100mm onto a DIY rail.
2) Looking at the sky is very aerodynamic - but your neck kills after a while craning forward to see where you are going. Foam and gaffer tape MK1 headrest sorted for next time. Why on earth would anyone attempt anything of a sporting nature without gaffer tape applied????
3) There is a reason Europeans run without the rowlock on the end of the boom. Mine has now gone.
4) When I lengthened the mast to raise the boom, i didn't buy a longer sheet, 200mm x 5 = me holding onto the last few mm. A meter short of a full sheet
5) My wonderful mast crane had been shorted and beefed up to stop bending, however I hadn't allowed for it so it was holding the sail too close to the mast and screwing the shape up.

Hopefully with this lot sorted next weekend should be a lot nearer to being right.
