Depends how fast the boat ... but if it were me, I'd be sure of a fresh bond cured for a solid 24 hours. I'd be sure of my hairline, and then go slicked straight back, working with the wind I'd be facing into. Then I'd bring along a baseball cap (just in case), which I'd consider wearing backwards, adjusted tight.

If it's like a speedboat/cigarette boat, and there's lots of humidity and sea spray, I might be too nervous to go w/out the hat ... a more traditional motorboat, and less sweaty/wet conditions, I'd probably feel comfortable hatless.

Sometimes, in boating situations on open water, there can be strong wind shears coming from multiple directions ... then my straight back style would be a mess, I'd wimp out and don the cap. It's nerve wracking, I know ... and if you'll be so nervous, you can't enjoy yourself, then play it safe w/ a tight cap and have fun !!!
