Fast Track to Sailing (Colgate) Flashcards
Keel
Heavy, fixed fin attached to the bottom of the boat that provides stability (loaded with lead)
Bow
Front end of the boat
Port side
Left side of the boat (when standing on the boat, facing ahead)
Starboard side
Right side of the boat (when you are standing on the boat, facing ahead)
Aft
Direction you are facing when turned towards the stern
Stern
Back end of the boat
Beam
Widest part of the boat (measures at largest distance from one topside of the boat to the other, not always at deck level)
Transom
Vertical or slated part of the boat, on the back end, that goes from the deck to the water
Astern
Behind the boat, off the stern end
Ahead
In front of the boat, off the bow end
Abeam
At a right angle from the boat
LOA
Length overall: total length of the boat from the bow to the stern in a straight line (not including bowsprit, if the boat has one)
Bowsprit
Pole that extends beyond the bow of the boat (not all boats have one)
LWL
Lower waterline length / waterline length: straight-line distance from the point where the bow emerges from the water to the point where the stern emerges from the water (necessary for calculating potential speed of the sailboat)
Draft
Vertical distance from the water surface to the deepest part of the boat (bottom of the keel), indicating where you can and cannot sail due to depth constraints
Draw
The water depth in which the keel of the boat would touch the bottom; “how much does your boat draw?” is answered with a depth measurement equivalent to the boat’s draft
Centerboard
Replaces the keel on some boats: a relatively thin panel made out of wood, fiberglass, or metal that can be raised or lowered to change the draft of the boat (these boats have two drafts, drawing a smaller number of depth units with the board up and a larger number of depth units with the board down)
Freeboard
Vertical height from water’s surface to the edge of the deck (important determinate of interior space; the more freeboard a boat has, the more headroom there will be in its cabin, if it has one)
Topsides
Sides of the hull above the waterline
Hull
Body of the boat
Cockpit
Where crew sits to operate the boat
Tiller
Attaches to a post that goes down through the hull to the rudder (moving the tiller moves the rudder)
Rudder
Fin-shaped blade attached to a pole underneath the boat, behind the keel, connected to the tiller; steers the boat by diverting water that is moving past it
Sloop
Single-masted sailboat
