in order move heavy objects.
tail

neatly so that it does not become tangled.
take in

telltale
A small line
free to flow in the direction of the breeze. It is attached to sails,
stays
in the slot
and in other areas, enabling the helmsman
and crew
to see how the wind is flowing. Proper use of the telltales can help sailors
improve their sail trim.
tender
A dinghy.
tidal current
Also called tidal stream. The flowing of water caused by the rising and lowering
tidal waters.
tide
The predictable, regular rising and lowering of water in some areas due to the
pull of the sun and the moon. Tidal changes can happen approximately every six
or 12 hours, depending on the region. To find out the time and water levels of
different tides, you can use tide tables for your area. The period of high water
level is known as high
tide, and the period of low water level is known as low
tide.
tiller
An arm attached to the top of the rudder
to steer a small boat. If the helmsman
wants to steer to starboard,
he pushes the tiller to port.
Larger boats usually use a wheel
instead of a tiller.
toe rail
A small rail
around the deck
of a boat. The toe rail may have holes in it to attach lines
or blocks.
A larger wall in place of the rail is known as a gunwale.
topgallant
1) Situated above the topmast
and below the royal
mast on a sailing vessel.
2) Higher than the adjoining parts of a ship: said of a rail,
deck,
etc.
top heavy
A boat that has too much weight up high. This can adversely affect the boat's
stability.
topmast
A mast

topsail
1) On a square-rigged
vessel, a sail
directly above the lowest sail on a mast.
2) On a fore-and-aft-rigged
vessel, the next sail above the gaff
of a fore-and-aft sail.
topsail schooner
A fore-and-aft-rigged
schooner
carrying a square topsail
and a topgallant
sail
on the foretopmast.
topsides
The sides of the hull above the waterline
and below the deck.
tow
To pull a boat with another boat, such as a tugboat towing a barge.
towing light
Running
lights that should be used by boats when towing to indicate that a tow
is in progress.
trade wind
Winds in certain areas known for their consistent strength and direction. Trade
winds are named because of their reliability, allowing for planned voyages along
the routes favored by those winds.
trailing edge
The aft
edge of a sail,
more commonly called the leech.
transit
Also called a range. Two navigational aids separated in distance so that they
can be aligned to determine that a boat lies on a certain line. Transits can be
used to determine a boat's position or to guide it through a channel.
transom
The aft
side of the hull.
traveler
A bar with an attached block,
allowing more controlled adjustment of sail
trim.
trim
1) To haul in on a sheet
to adjust the sail
trim.
2) Sail

Improperly trimmed boats may list

and two smaller outer hulls called amas.
trip line
A line

or higher in the Southwest Indian Ocean. In other parts of the world, they are
known as hurricanes,
typhoons
and severe
tropical cyclones.
trysail
Also called storm
trysail. A very strong
sail used in stormy weather. It is loose footed, being attached to the mast
but not the boom.
This helps prevent boarding waves from damaging the sail or the rigging.
tugboat
A small, powerful boat used to help move barges and ships in confined areas.
turnbuckle
A metal fitting that is turned to tighten or loosen the tension on standing rigging.
typhoon
An intense tropical weather system with a well-defined circulation and maximum
