Parts of A Boat

Length class 1

16 feet to less than 26 feet

Length class 2

26 feet to less than 40 feet

length class 3

40 feet to less than 65 feet

Displacement Mode

A planing hull, when operated at very slow speeds, will cut through the water like a displacement hull.

personal watercraft

A small vessel that uses an inboard jet drive as its primary source of propulsion, and is designed to be operated by a person or persons sitting, standing, or kneeling on the vessel rather than inside the vessel

Freeboard

Distance from water to lowest point of the boat where water could come on board

Cleat

Metal fitting on which a rope can be fastened

calculating boat capacity

Number of people = (boat length (ft.) × boat width (ft.)) / 15

stern drives

Stern drives are known also as inboard/outboards (I/Os) because they combine features found on both inboard and outboard engines. Stern-drive engines are four-stroke automotive engines adapted for marine use and are mounted inside the boat.

swamp

to fill with water

Displacement Hull

type of hull that plows through the water; it is slow but very strong: sailboats and cruisers.

Stern

back of the boat

jet drives

use an engine to power a strong water pump, which sucks up water and then forces the water out the back to thrust the boat forward. Personal water-crafts use these.

Gunwale

the upper edge of the side of a boat or ship

beam

Maximum width of a vessel

Float Plan for Extended Outings

- Describes the vessel, including its registration number, length, make, horsepower, and engine type. Includes the description and license plate of the tow vehicle and trailer. - Gives the number of passengers, their names and addresses, and a contact in case of emergency. - States where you are going, the detailed route, your planned departure time, and your expected return time. Include the location of all stopping points, dates, and times. - Gives the phone number for local authorities in case you fail to return when expected. If boating on waters under U.S. Coast Guard jurisdiction, give the phone number of the U.S. Coast Guard.

Fueling your boat

- Keep the nozzle of the fuel-pump hose in solid contact with the tank opening to prevent producing a static spark. - Use caution and fill the tank slowly to avoid spilling fuel into the boat's bilge (Interior of the hull below the floorboards; lowest part of a vessel's interior where the sides of the vessel curve in to form the bottom) or into the water. Use an oil-absorbent pad to catch drips or spills. - Never fill a tank to the brim—leave room for fuel to expand. - Wipe up any spilled fuel and properly dispose of the used paper towels or rags on shore.

After fueling

- Put the fill cap on tightly to prevent vapors from escaping. - Open all windows, ports, doors, and other openings. - If your boat is equipped with a power ventilation system (exhaust blower), turn it on for at least four minutes before starting your engine. This will help eliminate fuel vapors in the bilge. - Before starting the engine, sniff the bilge and engine compartment for fuel vapors. Continue ventilating until you cannot smell any fuel vapors. Consider installing a gas vapor detection and alarm device. - Start the engine and then reload your passengers. REMEMBER: Evaporating gasoline creates vapors or fumes that are heavier than air. These fumes settle to the bottom of the boat where they could explode if enclosed areas, such as the bilge, are not ventilated properly to remove fumes.

What to do before fueling your boat

- Tie the boat securely to the fuel dock. - Ask all passengers to leave the boat and go onto the dock. - Do not allow anyone in your group or others at the fuel dock to smoke or strike a match. - Check to see that fuel lines, connections, and fuel vents are in good condition. - Turn off anything that might cause a spark—engines, fans, or electrical equipment. - Shut off all fuel valves and extinguish all open flames, such as galley stoves and pilot lights. - Close all windows, ports, doors, and other openings to prevent fumes from entering the boat. - Remove portable fuel tanks from the boat and fill them on the dock. - Make sure that your fire extinguisher is within reach.

Multi-Hull

Another example of a displacement hull, the multi-hull has greater stability because of its wide beam. Needs a large area when turning.

Plowing Mode

As speed increases, a planing hull will have a raised bow, reducing the operator's vision and throwing a very large wake. Avoid maintaining a speed that puts your boat in plowing mode.

Hull

Body of a boat

draft

Depth of water needed to float a vessel

port

Left side of a boat

length overall

Length of the hull excluding any attachments

Length Class A

Less than 16 feet

tiller

Lever used to turn a rudder to steer a boat

keel

Main centerline (backbone) of a vessel or the extension of hull that increases stability in the water

starboard

Right side of a boat

propeller

Rotates and powers a boat forward or backward

rudder

Steering device, usually a vertical blade attached to a post at, or near, the stern of the boat

Deep Vee Hull

This planing hull gives a smoother ride than a flat bottom hull in rough water. Takes more power to move at the same speed as flat bottom hulls. May roll or bank in sharp turns.

Flat Bottom Hull

This planing hull has a shallow draft, which is good for fishing in small lakes and rivers. Rides roughly in choppy waters.

Round Bottom Hull

This typical displacement hull moves easily through the water even at slow speeds. Has a tendency to roll unless it has a deep keel or stabilizers.

capsize

To turn on the side or turn completely over

transom

Vertical surface at the back of the hull

Planning Hull

Vessel that rides up on the water, fast but not very strong: small driven boats, sometimes sail boats. 3 modes: displacement, plowing, planning

Planning Mode

Your boat is in planing mode when enough power is applied so that the hull glides on top of the water. Different boats reach planing mode at different speeds.

inboard engine

a four-stroke automotive engine adapted for marine use. Inboard engines are mounted inside the hull's midsection or in front of the transom.

outboard engine

a portable, self-contained package of an engine, gear case, and propeller that is attached to the transom of a boat

bow

front of a boat

Parts of a Sailboat

halyard: lines (ropes) used to raise and lower the sails Sheets: lines (ropes) used to control the angle of the sails to the wind
