Harness: A harness allows the
sailor to sail longer, by allowing the sailor to hook into
harness lines on the boom. Harnesses come in different
configurations: chest harness (high hook), waist harness (high
hook), and seat harness (low hook). For more info on
choosing a harness, click

| Harness lines: Harness lines
attach to the boom with webbing straps. Most harness lines
have a plastic covering on them to make them last longer, swing
less in the wind, and keep them from twisting. Harness
lines vary in length from 20" to 30" in length.
Some are adjustable, some are fixed length. Harness line
length is a matter of personal preference. People who use
harnesses with a higher hook tend to use shorter lines. To

| Harness hooks: Harness hooks
are the fittings that are attached to the harness which
"hook-in" to the harness lines on the booms.
Virtually all harness hooks nowadays are spreader
bars, which means that the harness hook is on a bar to
spread out the load better, and not squeeze the sailors ribcage
so much. |

Head: The head is the top of the
sail. On modern sails, the head is supported by battens,
and usually twists to
leeward as the wind increases. |

- IMCS:
"Indexed Mast Check System". This is a
standardized system for measuring the stiffness and curve of the
mast. The higher the number, the stiffer the mast.
Indexed MCS helps measure masts that are shorter or longer than
the arbitrary standard length (460 cm or 15'1"). For
example, a mast that is 400cm may have an IMCS of 19. This
means that if this mast were a 460, the MCS would be 19.
Lets say you had a 460 mast with an MCS of
25, and you cut it off to become a 400cm. Now this mast
would have an IMCS of much more, probably 30 or more. This
mast would be much stiffer than the example 400/19 mast
above. See also: IMCS number (mast
stiffness)
- Jibe:A jibe is a downwind turn in
which the tail of the board passes through the eye of the
wind.
Also can be spelled "gybe". See also Duckjibe
- Kevlar: Kevlar is the brand name
of the Du pont Corporation. Aramid fibers (a type of
Nylon) are generally called Kevlar, and has amazing tensile
(pulling) strength: highest of any commercially available
fiber. It also has excellent impact resistance.
Kevlar's weak charactaristic is in its compression
loading. Here it doesn't perform well. Kevlar is
often used for reinforcements on boards. It is very hard
to cut, or puncture, and was originally designed for use in
bullet proof vests.
Klegicell: see PVC foam.
