Hoist the main sail!
tighten the jib!
swab the decks you toothless scum!
ya, I get it (not really but hey, it would be fun goofing around on it)
I had a yachty mate I used to annoy by saying "belay the ratlins" constantly. He kepot on pointing out that Ratlins are fixed rigging and thus can't be belayed.
There's a water slide next to the yacht, the 8YO Japanese boy was vastly amused when a 210lb aussie went down it head first...
