What Is The Float Buoyancy Ratio?
The float buoyancy ratio is not a figure that is used for Farrier designs nor does this figure have much importance placed on it. The shape of the floats is a much more important factor for seaworthiness and performance. The ratio also depends on built weight which can vary widely, and the ratio on the F-25, for instance, can range from 120% to 180% depending on what version (for the same float). Float buoyancy and design are in fact frequently a misunderstood area of trimaran design with low buoyancy floats being generally regarded with suspicion or criticized, while high buoyancy floats are touted as faster and safer. High buoyancy floats are now used on Farrier designs, but low buoyancy floats were used in all earlier inshore Trailertri designs. Interestingly, these earlier submersible float designs have the best safety record of all Farrier designs, with the lowest wind capsize rate. They have in fact proved very forgiving, even being capable of coming back after a complete near 90
