    I know, brand new member starting a thread...

    The only one I could find on the topic has been cold for 10+ years, and had a vague title:
    Will this work? https://www.boatdesign.net/threads/will-this-work.9575/

    My dream: to build a sailboat to win The Operahouse Cup.

    Different classes of wooden monohulls, w times corrected by the Classic Rating Formula (CRF).

    I have some thoughts, but I'd love to hear suggestions of how to beat the formula. Only assumption is 26' length, to minimize cost.

    The first thing to consider are the predicted sailing conditions for the race and optimize the design for them. Of course, that is always a gamble, but one that is very common. Secondly, make a list of what you are allowed to do within the rule. This is the area where you can be creative.

    The race is on Nantucket Sound,

    Typical weather is 5-15 mph, and 1-2 ft seas.

    One way to optimize the rating formula would be to have multiple boats, each designed for different wind speeds, and then only choose one of them to race based on the forecast. That strategy isn't cost-effective, but it would probably be part of a cost-no-object strategy.
