    final GP Class rules

    Franco Dettori will be soon the new Chairman of the E.J.S.B.A. and this with my full agreement; Franco is for sure more “diplomatic” as me and I think this is an excellent choice.
    I will stay in charge of racing and Franco will be in charge of the “political relationship”
    Ski G.P. Class rules:
    The capacity for two stroke skis G.P. rise up from 800cc to 900cc
    The capacity for four stroke ski G.P. with turbo or blower go down from 1.100cc to 900cc
    Only one unit must be produced to receive the homologation.
    The hull, including upper and under hull are free but must stay in the sizes from the I.J.S.B.A “Ski Division” rules.
    Sponsons must be IJSBA race legal
    You can use any kind of composite material
    You can use any kind of engines but it must be based on a homologated “ski or R/A engine”
    If you want to make your own engine, this engine must be homologated by the EJSBA only for the G.P. classes.
    Full modifications are allowed (crankshaft, cylinders, pistons, crankcases and more)
    Two-cylinder maximum.
    Minimum weight is 114 kg
    Transmission and pump are free but must stay “inboard”
    The decision from the Technical Director is final about homologation of any G.P. ski.

    The capacity for two stroke R/A G.P. rise up from 1400cc to 1600cc

    Only one unit must be produced to receive the homologation.
    The hull, including upper and under hull are free but must stay in the sizes from the I.J.S.B.A “R/A Division” rules.
    Sponsons must be IJSBA race legal
    You can use any kind of composite material
    You can use any kind of engines but it must be based on a homologated “ski or R/A engine”

    Can't wait to see it here in the states. I'll have JUST the boat for it. If not, my racing money goes elsewhere.
