Mainsail- The sail that is attached to main, or largest, mast of a boat.
(LWL) length on the waterline - The vessel's length, including the rudder post.
Mackerel sky - A sky streaked with fine clouds, something in the manner of the stripes on the back of a mackerel.
[edit] LWL
Another measure of length is LWL (loaded waterline length) which is more useful in assessing a vessel's performance. In some cases (particularly old yachts or vessels with bowsprits) LWL can be considerably shorter than LOA.
LOA 45'; LWL 42'5'; Beam 15'; Draft 6'6'; Displacement 29,982 lbs.; Ballast 9,479 lbs.;
Sail area 1,114 sq. ft.; SA/D 18; D/L 175; L/B 2.88; Auxiliary Yanmar 75-hp; Fuel 156 gals.; Water 208 gals.
load water line (LWL)
A line painted on the side of the vessel to which the vessel sinks when carrying its full load.

Design Waterline (DWL) - Also length waterline or load waterline (LWL) - This is the length of the boat where it meets the water when loaded to its designed capacity.
Length on Waterline (LWL): This is the length at the waterline in the ship's design loaded condition.
Freeboard (F): Distance between the waterline and the uppermost watertight deck.
Sheer: The rise of a deck - usually toward bow and stern.
Length at the Water Line (LWL) Length Overall (LOA)
Line - A rope in use aboard a vessel
Line of Position (LOP) - A single magnetic bearing from a stationary marker “Magnetic Bearing' (MB) is another term for LOP ...
Length at the Waterline (LWL)
"LWL" is the measurement along the centerline at the waterline under a normal load.
LENGTH WATER LINE, LWL - length of the boat touching the water
LINE - Rope and cordage used aboard a vessel.
LOG - A record of courses or operation. Also, a device to measure speed.
The waterline length (length on the waterline, LWL; designed waterline length, DWL) is the straight-line distance between the boat's two extreme points at the water's surface. Length sometimes is an abbreviation for boat length.
HULL SPEED - The maximum practical speed of a displacement hull. To calculate, take the square root of the LWL (waterline hull length) and multiply by 1.34.
