My understanding is that the first USA Viper is heading to the gulf coast of Florida and will come with a carbon mast. It is reported to weigh 120 kg.

If I have this correct, emphasis has been placed on the rigidity of the Viper. Hence, the beams are central to this and will bring some extra weight. But I believe the logic is that the Viper will be a very stiff boat and the extra weight will not be a performance factor.

I am just relaying information that has been directed my way from AHPC. I am not an engineer.
