Re: 135 genoa vs 155 genoa
If you are racing under PHRF, keep in mind that your rating is influenced by the size of your head sails. You may find that the increased rating (i.e. decreased time allowance) off-sets any advantage conferred by the larger sail...
FWIW every and any PHRF racer in this area declares and uses a 150% (except for boats racing OD or white sail cruising class) or they just wont be competitive. When the 150% is an appropriate sail for the conditions, it is worth far more than the 3 sec/mile rating hit.
Certified...in several regards...
