Study Notes
Vessel Terminology
- Bow: Front of a vessel, crucial for navigation and mooring.
- Stern: Rear of a vessel, where steering mechanisms are often located.
- Starboard: Right side of a vessel; important for understanding navigational directions.
- Port: Left side of a vessel; often used in conjunction with starboard.
- Hull: Main body of a vessel, providing buoyancy and structural integrity.
Vessel Features and Components
- Gunwale: The upper edge of a vessel's side, significant for boat safety.
- Cleat: Metal fitting for fastening ropes, essential for securing vessels.
- Propeller: Rotating component that powers a boat forward or backward.
- Beam: Maximum width of a vessel, impacting stability and space.
- Freeboard: Distance from the lowest point of the boat to the water, indicating safety from capsizing.
- Draft: Depth of water required for a vessel to float, reflects boat size and waterway depth.
- Keel: Main centerline or backbone of a vessel, essential for stability in the water.
Hull Types
- Displacement Hulls: Designed for slow speeds; push water aside and require less propulsion.
- Planing Hulls: Built to glide on top of water at high speeds, demand more power.
Personal Watercraft (PWC)
- PWC Definition: Small vessel using an inboard jet drive, operated from a standing or sitting position.
Vessel Classifications
- Class A: Less than 16 feet.
- Class 1: 16 feet to less than 26 feet.
- Class 2: 26 feet to less than 40 feet.
- Class 3: 40 feet to less than 65 feet.
Engine Types
- Outboard Motor: Portable engine attached to the boat; includes engine, gear case, and propeller.
- Inboard Motor: Engine mounted inside the hull; adapted from automotive engines.
- Stern Drives: Combine features of inboard and outboard engines for versatile propulsion.
- Jet Drives: Power boats using strong water pumps for thrust; popular in PWCs.
Propulsion Components
- Intake Grate: Prevents debris from entering the water intake system.
- Intake: Opening that draws water toward the impeller.
- Drive Shaft: Connects the motor to the impeller for effective propulsion.
- Impeller: Forces water under pressure for movement; essential in jet propulsions.
- Steering Nozzle: Directs water flow for steering control at the stern of a PWC.
Rigging and Safety
- Halyards: Ropes used to raise and lower sails; crucial for sailboat navigation.
- Sheets: Ropes controlling the sail angle, impacting sailing efficiency.
- Capacity Plate: Indicates maximum weight and people capacity for safety during good weather.
Safety Terms
- Capsize: When a vessel turns on its side or completely over; a major safety concern.
- Swamp: Refers to filling a vessel with water, compromising buoyancy.
- Bilge: Lowest part of a vessel’s interior; collects water and requires regular maintenance.
Trailer Components
- Coupler: Attaches the trailer to the towing vehicle, vital for transportation.
- Tongue Weight: Weight pressing down on the towing hitch affects vehicle handling.
- Bunks: Wooden supports that hold the vessel while on the trailer, ensuring stability during transport.
