Learn the names of boat equipment.

The crews sit in rows behind a line.
The first crew member runs to the other side of the room and receives a card with the name of a piece of boat equipment on it.
He/she has 1 minute to draw it and the rest of the crew has to guess what it is.
If nobody in that crew knows what it is, the other crew has an opportunity to guess it.
Any crew member who knows the answer runs to a bell and rings it, before answering it. If the answer is correct, the crew wins a point.
The second crew member then runs to the other side of the room to collect a new card and so on.
The crew with the most points is the winner.

Start with simple things.
Vary the game with different anchors and more difficult boat equipment.
