sailboater! = hot dog sticks and refillable water jugs 
 
Just joking, I would be thinking something for the "boat". A nice wine bottle opener is a great gift. I bought a nice one for my buddy's wedding 9 years ago and they use it all the time. Tell me every time I see them it has been their best gift. It was from William Sonoma and at the time was $100+ lots of quality knock offs now.
