Starting or feature tread: Where stairs are open on one or both sides, the first step above the lower floor or landing may be wider than the other steps and rounded.
The first part of the code represents a numbered deck, the second part of the code is a hull support frame numbered sequentially from the bow, the third part of the code is a number representing compartment position with respect to the ship's centerline, and the fourth part of the code is alphabetic representing the use of that compartment.

In sailing, a boom is a spar (pole), along the foot of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. The primary action of the boom is to keep the foot flatter when the sail angle is away from the centerline of the boat. The boom also serves as an attachment point for more sophisticated control lines.
Binnacle.
