Spot the odd one out

Half day in Grenada, the Spice Island of the Caribbean.

The guy at next table remarked to the waiter how much he had enjoyed his dinner whereupon the waiter said:
“Would you like another another?”

“What ship are you on?” I ask handing back their camera after taking their photo.
 
“We’re not. We have a yacht. “
Oh….
