A Class

We have a small fleet of 5-6 A class yachts in the club and sail these as part of the “All Comers” series with many of the fleet entering national series and championship events.

Boats in this ISAF RSD international ‘open’ class are not limited in length, but are controlled by a formula which demands a balance between waterline length, displacement and sail area. Sails get smaller as displacement reduces and as waterline length increases. The formula was devised in 1922 by the editor of the Yachting Monthly as a testing ground for later use in the full sized 5.5 Metre class rule. Although boats are of a heavy ‘type’ there is flexibility to create lighter ‘models’. Nevertheless they are big boats and a fleet of radio ‘A’ boats is an impressive and awesome sight.
