    is there any advantage to having a v shaped foil over a straight one underneath a planing assymetrical powercat?
    is there any set place for placing rear foils on a such cat and is there a ideal length for rear foils?

    is this one of those deep dark and mysterious questions that are copyrighted?

    sorry but i have another question, i can understand how a foil is great in calm weather and small chop getting you up on the plane easier and therefore making a boat more fuel efficient but how do they handle the rough stuff doesnt having a big board stetched across the middle of the hulls become a bit of a negative in terms of bouncing off waves at speed?
