Study Notes
Boat Terminology
- Hull: The main body of a vessel, crucial for its structure and buoyancy.
- Bow: The front part of the boat, essential for direction and navigation.
- Stern: The rear portion of the boat, important for maneuvering and control.
- Port: Left side of the boat, indicated by a red light.
- Starboard: Right side of the boat, indicated by a green light.
- Keel: The structural backbone of the boat, providing stability.
- Gunwale: The upper edge of the boat's sides, where the hull meets the top structure.
- Beam: The width of the boat measured from port to starboard.
- Length: The total measurement from the bow to the stern.
- Draft: The distance from the waterline to the keel, important for ensuring adequate water clearance.
- Freeboard: The vertical distance from the waterline to the gunwale, impacting safety and stability.
Safety and Regulation
- Cleat: A device used for securing mooring lines.
- All around white light: Light positioned on top for vessel visibility in all directions.
- Red & Green Sidelight: Positioned at the bow for indicating vessel direction to others.
- Safety lanyard: A mechanism that activates a kill switch if the operator falls off a personal boat.
- Capacity plate: A required plate on vessels built after 1972, detailing passenger capacity and weight limits, found by the steering wheel.
Boat Mechanics
- Propeller: A rotating device that propels the boat forward or backward.
- Displacement Mode: A low-speed mode where a planing hull moves through water like a displacement hull.
- Plowing Mode: A speed mode causing the bow to rise and obstruct vision, creates a large wake—should be avoided.
- Planing Mode: A mode where the hull glides on the water surface due to sufficient power, achieving faster speeds.
Hull Types
- Displacement Hull: Designed to move through water by pushing it aside, suited for slower speeds; common in larger cruisers and sailboats.
- Planing Hull: Built to rise and glide atop the water at higher speeds, transitioning from displacement mode at rest.
Vessel Classes
- Class A: Vessels less than 16 feet in length.
- Class 1: Vessels 16 feet to less than 26 feet.
- Class 2: Vessels 26 feet to less than 40 feet.
- Class 3: Vessels 40 feet to less than 65 feet.
Measurement Terms
- Length overall (LOA): Measurement of the hull from the tip of the bow in a straight line to the stern, excluding attachments.
- Transom: The vertical surface at the back of the hull, critical for structural integrity.
Steering Mechanisms
- Tiller: A lever used to turn the rudder for steering the boat.
- Rudder: A device for steering, usually a vertical blade at the stern for directional control.
Engine Types
- Outboard engine: Offers more power per pound than inboard engines, typically four-stroke but some models are two-stroke.
- Four-stroke motor: An automotive engine adapted for marine applications.
- Conventional two-stroke motor: Requires a mixture of gas and oil.
- New technology two-stroke motor: Features direct injection for cleaner burning, achieving over 75% reduction in emissions.
