You can be competitive between 120kg - 150kg, depending on conditions. Ideal is about 135 - 140. I've sailed at 155kg at beaten the F18 fleet. (I don't know what that is in lbs sorry I don't have a weight converter on hand)

Given the predicted conditions I'd say the heavier crews will do better... the VIPER volume allows them to continue pushing in heavier conditions.

Looking froward to hearing from the guys on the ground there.
