A sleeve sail is ideal for sailing schools and intro sailing. A sleeve pocket at the luff slides over the mast with a cutout for the sprit halyard block. This sail is built strong to last long, made of 4 US oz. high quality 100% dacron sailcloth. The sail has 4 heavily reinforced corners, a loose foot and webbing loops at both the tack and the clew point to accommodate the boom. The sail does not have any battens and each of the 5 panels has a different color. Should be used with sleeve mastset EX1052.
