the Fox is a bit heavy at 420lbs..but living in the caribbean where 15-20kt wind and 4-6 sea is quite normal, the weight isnt really an issue. The Fox moves well in those conditions..and it does pretty well in europe..I think the main reason the the Fox didnt make it in the US is the fact that it is built for the Euro f-20 class and the US I-20 isnt,,the main rival of the Fox...the US I-20 has a bigger main and a carbon mast.bigger "engine" and lighter..going boat for boat wasnt really a fair test
