Our Boat - Handicaps

We can't always race one-design, so handicaps are one of those necessary evils.  Typically we race under PHRF when not just against each other. Sportboats are difficult to assign a single number, and U20s are a perfect example. Here is a boat that can hit 20 knots of boat speed. On the other hand an 1,100 pound boat with 19+ feet of waterline plunging through 3 ft powerboat chop needs a handicap boost compared to your standard 36 ft. PHRF boat. The upshot is that PHRF ratings are controversial wherever you go. Across the US they range from about 120 to 184 in different venues. The average seems to be in the150 range.

Ultimate 20 Handicapping Data

Following is the data that other new U20 owners may be required to supply to their fleets in order to obtain PHRF handicap certificates. Keep in mind that our effort is "handicapped" by the facts that (1) each different PHRF fleet does its own handicapping and may ask for different data, and (2) handicap dimension abbreviations are virtually unintelligible and are rarely defined on the forms.
