BAMA issues PHRF Handicaps for multihulls to race in the San Francisco Bay Area, Monterey Bay and Lake Tahoe at the request of the YRA PHRF Committee (NCPHRF) using their rules and guidelines with US Sailing guidance. BAMA PHRF Handicaps are determined relative to boats in the local Bay Area multihull fleet, using One-Design & National Association guidelines where they exist, other regional data, local race results and Rating Rules as applicable.


BAMA uses Texel (NDL, AUS, DEN, CSA), SCHRS (World Sailing), MOCRA (UK) and Multi2000 (FRA) Rating Rules for multihulls over 15 feet. The Rating may be used to calibrate the initial PHRF Handicap.


Initial PHRF Handicaps will be considered provisional in nature for boats new or unfamiliar to the committee. These handicaps may be reviewed and perhaps changed after one season or a series of races has transpired.


The BAMA PHRF Handicap Committee may decline to handicap any yacht for which it feels unable to determine a potential speed.


BAMA policy is all documentation must be submitted prior to issuing a PHRF Handicap. No handicap will be given over the phone or without full documentation having been made available to the entire committee.


The Committee may invalidate a Certificate at any time where cause is in evidence such as incorrect dimensions or other than declared equipment is used. Due process will be exercised to allow the owner to be heard and corrections made if the owner in the view of the Committee provides justification.




BAMA recommends that multihulls & monohulls should not be scored in the same section or division in any competitive event in alignment with US Sailing PHRF (2).
