2. The main function of a boat’s keel is to:

• Provide storage space
• Support electrical systems
• Provide structural stability and reduce lateral motion
• Anchor the rudder assembly

Rationale: The keel stabilizes the vessel, minimizes side-slip, and bears

structural loads.

• When laying up fiberglass, what is the purpose of using a roller?
• To heat the resin
• To apply gelcoat
• To remove air bubbles and ensure even resin distribution
• To cut the mat

Rationale: Rolling eliminates trapped air that weakens the laminate and

ensures proper resin saturation.

• What is the primary function of the transom on a boat?
• To hold the steering wheel
• To support the engine and connect the sides of the hull
• To direct water flow
• To store fuel

Rationale: The transom provides mounting for outboard motors and

• The angle between the bottom of the hull and the horizontal plane
• The distance between frames
• The curvature of the deck

Rationale: Deadrise indicates hull shape and affects speed, stability, and

handling in waves.

• What type of wood is most commonly used for marine plywood?
• Maple
• Oak
• Okoume or Mahogany
