If they were block to block the sail would not have proper flow. Believe me when I broke a boom to leech shackle on my Hobie 17 in a Wed night race I learned the meaning of it REAL fast. I had to southern construct one out of line. Lot of difference in 2" and 12" I was block to block way before the main was sheeted in enough and had 12' under boom on tacks. REAL bad DAY. DN's are sweet boas.

Doug, have ever even seen a DN ice boat except in a picture. With the mast rake and mast flex the DN goes block to block to depower. Get a clue before responding next time.
