Lesson 1 of 8
Parts of a Boat — Fore and Aft
Active recall
Section 1 of 8
A crew member is told to move aft. Tap where they should go.
Why it matters on board
The front of a boat is the bow. The back of a boat is the stern. Anything towards the bow is described as forward or fore; anything towards the stern is aft. The midpoint of the vessel is amidships.
These terms are used constantly in Day Skipper theory, marina instructions, pilotage notes, and safety briefings. For example, a crew member asked to move forward should go towards the bow, while equipment stowed aft is towards the stern.
The bow typically has a pointed shape to cut through waves. On a yacht the deck area at the front is the foredeck. The stern may include the cockpit, bathing platform, boarding ladder, pushpit, or dinghy davits depending on the boat.
Terms to know
- Bow — the front of the vessel
- Stern — the back of the vessel
- Forward / Fore — towards the bow
- Aft — towards the stern
- Amidships — the middle of the vessel
Watch for this
Port and starboard describe left and right. Fore and aft describe front and back.

Lesson 2 of 8
Port and Starboard
Active recall
Section 2 of 8
Which term means “left side when facing forward (red)”?
Why it matters on board
When facing forward, the left side of the boat is port and the right side is starboard. Port is associated with red (navigation lights, buoyage) and starboard with green.
A useful mnemonic: 'port' and 'left' both have four letters. Another: 'Is there any RED PORT LEFT in the bottle?'
Terms to know
- Port — left side when facing forward (red)
- Starboard — right side when facing forward (green)
Watch for this
Remember: 'port' and 'left' both have four letters.
Lesson 3 of 8
Hull and Below the Waterline
Active recall
Section 3 of 8
Which term means “the body/shell of the boat”?
Why it matters on board
The hull is the body of the boat. The waterline is where the hull meets the water surface. The draught is the depth of the hull below the waterline — critical for knowing what depth of water you need.
The keel is the structural backbone running along the bottom of the hull. On sailing yachts, the keel extends downward to provide stability and resist sideways drift (leeway). The rudder, mounted at the stern, steers the boat and is controlled by a tiller or wheel.
Terms to know
- Hull — the body/shell of the boat
- Waterline — where the hull meets the water
- Draught — depth of hull below waterline
- Keel — structural backbone; provides stability
- Rudder — steering surface at the stern
- Freeboard — height of deck above waterline
- LOA — Length Overall of the vessel

On Deck

Section 4 of 8
Which term means “main crew area with helm controls”?
Why it matters on board
The cockpit is the recessed area in the deck where the crew sit and the helm (tiller or wheel) is located. The companionway is the entrance/stairway leading below deck. Guardrails (or lifelines) run around the deck edge for safety, supported by stanchions.
Cleats are fittings used to secure ropes. A winch is a mechanical device for hauling ropes under load — essential for controlling sheets. A fairlead guides a rope in the desired direction. The pushpit is the guardrail frame at the stern, and the pulpit is the same at the bow.
Terms to know
- Cockpit — main crew area with helm controls
- Companionway — entrance to below decks
- Cleat — fitting to secure ropes
- Winch — mechanical device for hauling ropes
- Pulpit — bow guardrail frame
- Pushpit — stern guardrail frame

Below Decks

Section 5 of 8
Which term means “main cabin / living area”?
Why it matters on board
The saloon is the main living area below deck. The galley is the kitchen. The heads is the toilet/bathroom. Berths are the sleeping areas — they may be in the forecabin (forward cabin), quarter berths (aft), or in the saloon itself.
The chart table is the navigation station where charts are plotted. Many modern yachts have electronic chart plotters here alongside traditional paper charts.
Terms to know
- Saloon — main cabin / living area
- Galley — kitchen
- Heads — toilet and washroom
- Berth — sleeping place
- Chart table — navigation station
Lesson 6 of 8
Standing and Running Rigging
Active recall
Section 6 of 8
Which term means “fixed wires supporting the mast (shrouds, stays)”?
Why it matters on board
Standing rigging is the fixed wires that hold up the mast — shrouds run from the mast to the sides of the hull, the forestay runs forward, and the backstay runs aft. These are tensioned and rarely adjusted while sailing.
Running rigging is the ropes you actively use to control sails. A halyard hoists a sail up. A sheet controls the angle of a sail to the wind. The mainsheet controls the mainsail, the jib sheets control the headsail. The boom is the horizontal pole along the foot of the mainsail, controlled by the mainsheet and kicking strap (or vang).
Terms to know
- Standing rigging — fixed wires supporting the mast (shrouds, stays)
- Running rigging — ropes used to control sails
- Halyard — rope that hoists a sail
- Sheet — rope that controls the angle of a sail
- Boom — horizontal pole at the foot of the mainsail

Section 7 of 8
Which term means “towards the wind”?
Why it matters on board
Windward means towards the wind; leeward (pronounced 'loo-ard') means away from the wind. Ahead means in front of the vessel, astern means behind. Abeam means at right angles to the centreline.
A vessel's heading is the direction the bow points. Her course is the intended direction of travel. The track is the actual path over the ground (which may differ from the course due to tide and leeway). A bearing is the direction of an object measured from the vessel.
Terms to know
- Windward — towards the wind
- Leeward — away from the wind (pronounced 'loo-ard')
- Heading — direction the bow points
- Course — intended direction of travel
- Track — actual path over the ground
- Bearing — direction of an object from the vessel

Section 8 of 8
Which term means “to secure a rope or line”?
Why it matters on board
To make fast means to secure a rope. To cast off means to release the mooring lines and depart. Fenders are inflatable cushions hung over the side to protect the hull when alongside a pontoon or another vessel.
To tack is to turn the bow through the wind when sailing upwind. To gybe (or jibe) is to turn the stern through the wind when sailing downwind — this requires care as the boom can swing across violently.
Terms to know
- Make fast — to secure a rope or line
- Cast off — to release mooring lines
- Fender — protective cushion hung over the side
- Tack — turn the bow through the wind
- Gybe — turn the stern through the wind
