Sea Kayaking Glossary
|open ocean -
on this website, any salt water not protected from waves or swells originating at sea; waters receiving the full force of ocean weather.
a wind blowing in the direction of travel.
technical clothing -
garments made from a fast-drying fabric that does not absorb water and therefore allows rapid evaporation of water and sweat. Usually made of wool or a synthetic fabric like polypropylene.
influenced by the tides.
tidal current -
the movement of water caused by the tides.
tidal current predictions -
a table showing predicted times and velocities of both slack water and maximum flood and ebb currents for a given location.
tidal river -
a narrow inlet from the ocean usually experiencing strong tidal currents.
the regular increase and decrease of water levels on the ocean.
tide predictions -
a table of forecasted times and heights of high and low tides for a given location.
tide rip -
choppy, confused seas caused by moving water, frequently seen in areas with strong tidal currents. Not equivalent to a riptide.
tide tables -
top of the tide -
the period of time near high tide; for example, the top half of the tide includes three hours on each side of high tide.
topographic map -
a map of a region of land showing elevation, contours, buildings, bodies of water, and roads. Not designed for navigation on water. Official topographic maps in the US are produced by the US Geological Survey.
tow rope -
a rope mounted on a kayak to enable the towing of another kayak.
true north -
the direction pointing toward the geographic north pole of the earth. Longitude lines point directly toward true north. Directions given relative to true north should be noted, for example, "195 degrees true."
water level -
the height of water, relative to MLLW, at a given time.
to a mariner, weather consists of wind, ocean swells, rain, and fog.
weather radio -
(1) a network of transmitters covering most of the US that continuously broadcasts current NWS weather forecasts for the local area. (2) a device that receives broadcasts from such a network.
a tight-fitting, full-body, neoprene garment that decreases heat loss when the wearer is submerged in water by preventing the circulation of cold water against the wearer's skin.
wet exit -
to exit the boat when capsized by releasing the spray skirt.
in a south wind, air moves from the south toward the north.
the direction from which the wind is blowing, relative to your current position.
windward shore -
when you are on the water, a windward shore is the shore from which the wind is blowing.
wind-driven current -
a current, flowing in the same direction as the wind, occurring in the top layer of water exposed to wind. The maximum speed of a wind-driven current is 3% of the wind speed.
