A camera crew showed some catamarans briefly at the end of stage 17 today.

They looked about 18ft, all the same, had pin top mains with alot of roach. They were sloop rigs, with jibs. NOthing fancy, no spin poles, wings, etc.

I;ve seen a;ot of boats, but I could not identify these.

They had what looked like maybe a snake, in the shape of a large 'S' near the tip of the main. Then they had what looked to be 'F2' the f in cursifs(sp?), near the bottom.

What are those?
