I wear contacts when I sail without any problems. I wear the kind that is "supposed" to be changed every three months......like that ever happens. I used to windsurf in the Gorge in gnarly conditions, looping, jumping, crashing at superspeed and never lost a contact. I've opened my eyes underwater a few times for a split second, before remembering I shouldn't be doing that and still haven't lost one. You'd be surprised how quick your eyes shut when a wall of water is coming towards them.

There was one time my contact got folded underneath itself, but I was able to fix it quickly. Windsurfing, I wear no sunglasses, but have them on 95% of the time when on the cat. Just make sure you have well fitting contacts and mention that you sail to your optometrist and he/she may be able to help.
