Latitude Photo Quiz

Every boat ever built has had mysterious and strange modifications made to it by its many owners. One couple we know, who bought their boat from a gentleman named Bob, calls them ‘Bob Jobs’. This writer and her husband have a decidedly less polite term for them. Occasionally, they can be brilliant, but most of the time they’re annoying, and every once in a while just plain dangerous. It’s sometimes difficult to even figure out their original purpose. Ah, the joys of buying a used boat!

Today’s quiz is something that diver Tim Sell found on a boat for her new owners. What is it?

UPDATE: Our quiz was just too easy. We’ve received so many correct answers we’re cutting it short. We’ll have the correct answer on Wednesday. Thanks for playing!
