ALBERG GREAT LAKES AND CHESAPEAKE BAY ASSOCIATION RULES/DIMENSIONS
Main Size: Luff 31' max
	   Foot 14' 3" max
	   Leech 33'6" max
	   
Advice: Build to the max but small shelf and fairly flat cut with the
angle at 90 degrees, luff to foot.  Use full battens and a two-ply
leach.   Don't lower the boom, SAFETY and illegal for racing.
