When a Roller furling Genoa is reefed to be a smaller sail the
smaller size sail shape is not as good as the full size sail
shape, as the sails draft is in a new position. To compensate for
this, sailmakers add foam along the sails luff. Thus, as the sail
is partially furled, the foam adjusts the sails draft for better
performance as a roller reefed sail.
The better performing furling sails have a foam luff. Foam will be
5mm thick, and normally we cut the foam 5cm wide.
The Max number of strips we go to is 4 pieces, depend on sail
Foam Strip Specs;
Width from Tack : 33% * Luff
width thickness : 2.5% * Luff
Foam swidth : 45mm
Foam luff can
be made rope style by request, we would supply the rope
The foam can
be made pad style by request. This would be one big pad in place
of the multiple strips shown.
