Yacht Types and Main Parts at a Glance

Split yachts into sail-first and engine-first

In everyday speech, many large leisure boats are called yachts. For license and operating decisions, the distinction matters. The Korea Coast Guard license guide points to the yacht operator license for sailing yachts. A motor yacht should be checked by actual structure, propulsion, and official registration or inspection information.

Common yacht types

Type	What it is	Beginner check
Dinghy	Small, light sailing yacht, usually without a cabin	Often used for training; expect body movement and getting wet
Keelboat	Sailing yacht with a weighted keel under the hull	Check draft, dock depth, crane, and mooring conditions
Cruising sailing yacht	Sailing yacht with cabin and auxiliary engine	Requires sail handling plus engine, electrical, and living-system upkeep
Catamaran	Twin-hull yacht with two hulls side by side	Stable and wide, but berthing space and handling feel differ
Motor yacht	Yacht-style boat primarily powered by engine	Fuel, engine maintenance, license rules, and berthing cost matter most

Main sailing-yacht parts

Part	Role	What to check
Hull	Body that floats on water	Cracks, leakage, draft, stability
Mast	Vertical spar that supports sails	Movement, rigging tension, height
Boom	Horizontal spar under the mainsail	Swing range and head-strike risk
Mainsail	Main sail	Tears, wear, line handling
Jib or genoa	Forward sail	Furling gear, visibility, tangled sheets
Sheet	Line that controls sail angle	Wear, knots, winch wrapping
Halyard	Line used to raise and lower sails	Friction, twist, locking gear
Keel or centerboard	Resists sideways drift and adds balance	Depth, grounding risk, damage
Rudder	Steering blade	Play, damage, response
Tiller or wheel	Control used to move the rudder	Feel, position, emergency steering
Winch	Helps handle loaded lines	Hand safety, reverse rotation, proper use
Cockpit	Area where crew sit and operate the yacht	Drainage, movement, safety lines

Terms that often confuse beginners

• Sailing by wind: the route is planned relative to wind, not only the destination direction.
• Trimming sails: it is not a simple throttle. You adjust sail angle and tension.
• Keel and draft: a deeper keel can help stability but makes shallow water and docks more important.
• Mast height: bridge clearance, land storage, and transport limits depend on it.

Suggested learning order

1. Decide whether it is a sailing yacht or motor yacht.
2. Learn wind direction, port, starboard, windward, and leeward.
3. Be able to explain mainsail, jib, sheet, rudder, and keel in plain words.
4. Practice docking, undocking, mooring, and turn-back decisions first.
5. Tie license, weather, current, depth, and safety gear into one pre-departure checklist.
