Dear Sirs,

As most of you probably know, curved centerboards = have been greatly discussed after European Championship in La = Baule.

It is scientifically proven that these boards = create a vertical lift and an “hydrofoil effect” and that is why they = were developed.

ISAF rule balloted in 2002 is : “Hydrofoils = are not permitted”. Given that we know that curved centerboards formally = comply with 2006 box rule nevertheless they are against the spirit of 2002 ISAF = rule.

Even if we are a development class and we are all = proud of this, a IACA Commission is working on this subject, trying to make a = rule to stop extreme developments.

IACA Committee and myself as President ask you all to be very = careful and wait with any production until the rules are clear otherwise there = is a significant risk to waste money and to cause a lot of ill feeling in = your customers. It does not make sense to produce a boat that could be not = allowed.

Please forward this message to whoever is not included in the mailing list and = could be involved by this matter.

Kind regards

International A Class Association
