Orient Yourself Before Naming the Boat
From Boat Language and Keelboat Parts
What you will learn
Use the boat itself as the reference frame for bow, stern, port, starboard, forward and aft, regardless of where a crew member is facing.
Explanation
Boat language removes the ambiguity created by a person’s changing viewpoint. Start with the bow, then name the vessel’s sides and directions from that fixed reference.
Bow and stern name the forward and after ends of the vessel. Forward or fore means toward the bow; aft means toward the stern. Port is the vessel’s left side and starboard its right side when looking forward. Those sides remain attached to the boat: a crew member who turns to face aft does not make port become starboard.
Ahead and astern describe positions or movement beyond the bow and stern. Abeam means roughly at right angles to the vessel’s fore-and-aft line. Windward and leeward use the wind as their reference, so they can change when the wind or the boat changes; port and starboard do not.
Translate a call without using the crew member’s viewpoint
The helm is facing forward. A crew member beside the mast is facing aft. The helm calls, ‘Take the port jib sheet forward and keep it clear of the hatch.’
Sense check: The crew member’s chest is facing the stern, but the port side of the boat has not moved.
Common mistake
Left and right follow the observer; port and starboard remain fixed to the vessel.
Recap
- Bow and stern are the ends; fore or forward and aft describe direction along the boat.
- Port and starboard stay fixed to the boat.
- Windward and leeward can change with the wind or the vessel’s heading.
