101 Flashcards
Keel
A fixed appendage on the bottom of the hull that provides sideways resistance needed to counter the force of the wind on the sails. The keel also carries ballast, usually iron or lead, the weight of which counteracts the force of the wind that causes a sailboat to heel, or lean over.
Hull
The watertight structural shell of a boat.
Bow
The forward part of a boat
Stern
The aft part of the boat.
Transom
The more or less flat surface that closes the hull at the stern
Rudder
The sailboat is steered by a fin-shaped appendage attached beneath the boat toward the stern which can be rotated to change the angle at which the water strikes it. Water must flow past the rudder in order for it to work so it will not turn the boat while at rest. The rudder is controlled by a wheel or a tiller at the helm of the boat. The person steering the boat is the helmsman.
Cockpit
The area of the boat, usually recessed into the deck, from which the boat is steered and sailed.
Deck
The generally horizontal surface that encloses the top of the hull.
Companionway
The entrance from the cockpit or deck to the cabin.
Stanchion
A metal post that supports lifelines.
Lifeline
A wire supported on stanchions around the perimeter of the deck to prevent the crew from falling overboard.
Pulpit
A guardrail at the bow or stern of a boat to which (usually) the lifelines are connected.
Sailing Dinghy
A small sailboat is usually under 20 feet long and open for most of its length. A dinghy has neither a keel nor a ballast. To resist sideways movement it has a centerboard or a daggerboard that can be lowered or raised as needed.
Keelboat
A keelboat is generally larger than 20 feet and can be as large as a megayacht at 200 feet. Unlike a dinghy, a keelboat won’t capsize. In a strong wind, it may heel a long way over, but the ballast in its keel is designed to keep it from capsizing.

Attach the hanks to the forestay

Attach the two jib sheets to the clew with a bowline knot.

TYPES OF PFDS
Type I: Most Buoyant - WILL roll unconscious person face-up, used in rough water and required on commercial vessels.
Type II: Near-shore buoyancy vest - Foam vest MAY turn an unconscious person face-up.
Type III: Flotation aid. (inland use) - Intended for light use, presumes a conscious person. More comfortable than Type I. Examples: waterski vests, fishing vests, and belt-pouch inflatables.
Type IV: Throwable Device - Not designed to be worn. Thrown to the victim in water to grasp until rescued. Examples are horseshoe buoys, life rings, and floating cushions
Type V: Special-use Device - Hybrid devices such as hypothermia suits, work vests, commercial deck suits, and inflatable life vests.
Safety equipment on boat
- LIFE JACKETS - PFD PERSONAL FLOTATION DEVICE
- VISUAL DISTRESS SIGNALS
- SOUND PRODUCING DEVICES
- FIRE EXTINGUISHERS
- NAVIGATION LIGHTS
Two ways to stop a sail from luffing:
- Bear away
- Trim the sheet
When in doubt — let it out!

Head-On Situation
Bowline
The bowline forms a temporary eye, or loop, in the end of a line and is commonly used to attach a jib sheet to the clew of the jib
Figure-Eight Knot
The figure eight is bulky, and serves well as a stopper knot, and is easily untied.
Square Knot
On a boat it is used primarily for tying a rope to itself
Cleat Hitch
Around the clear. Last loop under
Clove Hitch
The clove hitch is usually employed for temporary needs.
Main and Jib sheet
Type of fire extinguisher on boat
Type B is a petroleum (fuel) fire, and Type C is an electrical fire
Select all correct steps when fighting a fire onboard a sailboat
- Operate the fire extinguisher using the PASS method
- Leave yourself an escape route.
- Make an emergency VHF call

To recover a Man Overboard with controlled speed and maneuverability, the final approach under sail should be
Close reach with sails luffing, keeping the MOB to leeward
Leeward
Situated on or toward the side sheltered from the wind; downwind.
Windward
Facing the wind or situated on the side facing the wind.
When recovering a Man Overboard under power, approach into wind so that when alongside the MOB, the boat is:
