Anyone on the boat does one of two things:

1) Listens, stays focused on the task at hand, and keeps out of your field
of vision. They do not move about emptying ash trays or picking up empty
drink containers.

2) Goes in the cabin, preferably tied securely to an immovable structure.

Boys between 14 and 18 will be looking around for skirts instead of helping.
Yell the kid's name sharply every 30 seconds, even if there's not another
living thing for a mile in any direction. They need to understand that for
the 5 minutes it takes to dock the boat, they can stop looking for skirts.

When you get really good at docking, some people will think everything's
different and that they can chatter at you about all sorts of annoying
things. These people go in the cabin (see #2 above).
