Best/coolest thing you ever saw on a ship?

Jemplayer,
I was dancing with a seaturle last week on a night dive at “barracuda rock” in Guam. They’re awesome underwater and fun to play with at depth, but a tiger shark decided to show up an spoil the fun according to the dive shop. I haven’t gone back after hearing that…not at night anyway. I’m going to “Haps Reef” tomorrow night (near the area)…hopefully, my turtle friend is still around.
