    Seriously, about 8 - 10 knots depending.

    8 knots if you are lucky 6-7 is more realistic

    I do agree totally. 6 knots.
    The Prout cats were painfully slow. In fact slower than some good monohulls of the same length and period. The combination in the style Dick Carter IOR of a very small mainsail and big jibs and genoas on a aft mast required big winches and constant adjustments when apparent wind changed at any acceleration.
    The wetted surface was enormous with the keels, in a light wind the motion was a pain for a lover of vivace boats. I learnt all that helping to convoy a Sprout Snowgoose from Piraeus Greece to Marseilles France in 1983. We ended using a lot of fuel...
    In discharge these cats were designed to be comfortable and immediately usable by any monohull guy.

    I worked at prouts for a while & was surprised at the almost complete lack of quality control, the building teams were basically just left to get on with it. The boats were heavy for cats & often they would use 10 or 12mm ply in panels in galleys etc when 6mm would have been more than adequate. Also there was a huge variance in weight depending on which build crew built each boat. I was on a team building one of the first 45ft cats. We used 4 x 25kg drums of crestomer to bond bulkheads & structurals in & 5 x 25kg drums of flow coat to gel out the lockers. The supposedly identical boat build by the next door crew used 9 & 12 drums of the same stuff! They were equally as sloppy when tabbing in the bulkheads & structurals & used twice the resin we did. Result was that boat went several tons heavier on the crane when she went out. This aint good on a catamaran.
    Saying this I knew one of the directors who had a 37ft Elite. that boat had a bigger rig than standard & had been built carefully & down to weight. Late 80's I was on Southend pier helping as one of the spotters for the race officer at the finish of the Nore race, It was blowing a strong nw breeze & that Snowgoose came over the line on a close fetch & she was being pushed really hard & going like a train. Never seen one since flying a hull but they managed it on that day.
