Multi-Hull Fleet

Welcome the home page for AYC’s Multi-hull Fleet. The fleet for Trimarans and Catamarans.  This is where to find out about the multihull fleet’s activities and multihull racing information.  The Multihull Fleet participates in all Series Races at AYC, as well as local and Regional Regattas.

2020 Fleet Captain : Jim Casto

With so many different multihull boats, racing at AYC is scored using handicap ratings.

Currently, we use PHRF Time-On-Time across all boats, including trimarans and catamarans.

The fleet captain, is maintaining a database of PHRF numbers for all the multihulls (i.e. not the Keel Fleet PHRF Committee).  For adjustments, modifications or corrections, please contact the fleet captain.

Current list of multihull PHRF number is HERE = AYC Multihull page on Google Drive

Additional resources : Corsair reference PHRF sheet (from RegattaNetwork)

US Sailing info on PHRF

Scoring Committee uses current list of PHRF Handicap numbers to produce scores.  Scoring Committee are not the source of the PHRF number used to produce the score, only the “scorer”.  If you see scoring errors (missing data, wrong PHRF used, etc), contact them at  Do not contact them to have your PHRF changed due to equipment change, new TOMA rating, etc.  To change your actual PHRF number, contact the fleet captain, who maintains the PHRF database for the fleet.

When catamarans race as a class, we use the Portsmouth Yardstick Index
