Tamiya had a modern sailing crew in 1/20 scale, which is out of production, however the figures are actually the same as their F1 pit crew. The pit crew set is offered in 1/20, 1/32 scales.
I must agree with the earlier reply though, in that crew offer more chances of snagging sheets etc... My 1/96 scale cruiser has over 100 crew about the deck, however, my 1/20 scale Schooner only has a helmsman.
