Nautical Terms Flashcards
What is the keel
a large fin below the boat, lowing its centre of gravity, and increasing stability
What types of keel are there
Long keel, fin keel, bilge keels
Advangaes of long keel
Better directional stability and heavy weather sailing
advantages on fin keel
better handling under light winds,, better manoverability,
advantages of a bilge keel
boat can try out, and be fine
What is a sail drive
A sail drive is a propeler on a vertical post out the bottom of the hull of the boat.
What is a shaft drive
A shaft drive is a properller attached at an angle through the bottom of the hull.
Advantages of Sail drive
Close coupling of engine and drive no alignment or vibration problems and smaller installation.
Coupling of engine, drive and prop inherently stronger and less prone to failure.
Propellors are often deeper in the water, less prone to fouling and better drive.
Less regular routine maintenance of drive train
Advantages of Shaft Drive
More Reliable
Less expensive to maintain
Failer is less catastrophic
What is the rudder
A fin placed at the back of the boat, articulated to turn the boat
Why is setting the sails important for the rudder
The rudder acts as a break, so if the sails are not set correctly, it will turn the boat requiring the rudder to counteract, slowing the boat
When the setting of the sails causes the boat to turn to windward, what is that called
Weather helm
When the setting of the sails causes the boat to turn to leeward, what is that called
Lee helm
What is the backstay
The large metal wire running from the stern of the boat to the top of the mast. it is part of the standing rigging
What is a Split backstay
2 wires running from the port and starboard quarters and joining at the mast
what is a divided backstay
2 wires running from the port and starboard quarters, joining partway to the mast.
What is the Pushpit
The pushpit is the metal gardrails around the stern of the boat
what is the pullpit
the pulpit is the metal guardrails at the bow of the boat
what are the guard rails running the length of the boat held up by
stanchions
What is one thing that the guardrails cannot be used for
clipping a safety line to
what is the forestay
The wire running from the bow to the head of the mast
what is often found on the forestay
a roller fuller, with the jenny or foresail, rolled around it
What are the 2 uses of the foresail sheet
to control the jenny/foresail during sailing, and to unfurl the sail from the rollerfurler
What is the furling line for
furling the headsail, or adding reefs to the foresail
