-- Should the skipper manage to fall into the water while attempting to clamber from the dingy to the dock, it is considered impolite for scurvy crew members to point and laugh hysterically. Proper seamanlike demeanor is called for in this situation. Also beer.

-- Having water in the bottom of your dingy makes it both unsafe and uncomfortable for use. Always bail excess water into an adjacent dingy before departing the dock.

-- Approaching and departing dingy docks should always be accompanied by the loud singing of sea chanties, drinking songs, or college fight songs if a fight is what you're looking for.

-- If crowded conditions have forced later arrivals to raft up to your dingy, upon your departure it is only good manners to lash their flashlight pointing skyward and turned on in order to help them locate their dingy as it drifts out of the harbor in the dark.

-- As most dingy docks are relatively narrow, always remember to leave all sandy flip-flops, damp beach towels, empty beer cans, life jackets, and excess docking line in a neat pile in the center of the dock, thus reducing the risk of any of the items being accidentally kicked into the water by other less considerate seamen transiting the area.
