The main parts of a yacht are the bow (front), stern (back), hull (body), deck (walking surface), helm (steering station), cabins and berths (sleeping quarters), the galley (kitchen), the head (bathroom), and the flybridge (upper deck). Port is the left side and starboard is the right when you face forward.

Step aboard a yacht for the first time and the vocabulary can feel like a foreign language. Knowing the names is not just etiquette, it helps you communicate with crew, understand a listing, and move safely around the vessel. This guide breaks down the anatomy of a yacht in plain English, from the structural basics to the features that define a modern motor yacht. Allied Marine has sold and surveyed yachts since 1945, so the terms below are the ones brokers, captains, and owners actually use on the dock.

The main sections of a yacht

Before the individual parts, it helps to picture a yacht in four zones:

• Forward: everything toward the front, or bow.
• Aft: everything toward the back, or stern.
• Topside: the decks and structures above the waterline.
• Below deck: the living spaces, machinery, and systems inside the hull.

Almost every term below falls into one of these zones, which is why a captain can give directions with a single word.

Directional and orientation terms

These are the words that confuse newcomers most, so they come first.

• Bow: the front of the yacht.
• Stern: the back of the yacht.
• Port: the left side when you face the bow.
• Starboard: the right side when you face the bow.
• Forward and aft: toward the bow and toward the stern.
• Beam: the width of the yacht at its widest point.
• Amidships: the middle of the vessel.

A simple memory trick: “port” and “left” both have four letters.

Structural parts of a yacht

These are the bones of the vessel, the parts a marine surveyor examines most closely during a purchase.

• Hull: the main watertight body that sits in the water and gives the yacht its buoyancy and shape.
• Keel: the central structural spine along the bottom of the hull, important for stability and, on sailing yachts, for countering the wind.
• Deck: the horizontal surface that caps the hull and where you walk and relax.
• Gunwale: the upper edge where the hull meets the deck.
• Transom: the flat, near-vertical surface across the stern, often where the yacht’s name and the engines or drives are found.
• Freeboard: the distance from the waterline to the top of the deck.
• Draft: the depth of the yacht below the waterline, which tells you the shallowest water it can safely enter.

Draft matters more than beginners expect. A yacht with a deep draft cannot reach certain shallow anchorages and marinas, which is worth checking against your cruising plans.

Decks and topside features

This is where a modern motor yacht differs most from a small boat, and where many online glossaries fall short.

• Flybridge: an upper deck above the main cabin, usually with a second helm, seating, and often a bar or sunpad. It is one of the most sought-after features on a cruising yacht.
• Cockpit: the aft outdoor area, typically just behind the salon, used for dining, fishing, or boarding.
• Foredeck: the deck space forward of the cabin, often with sun lounges.
• Hardtop: a fixed roof over the helm or cockpit that provides shade and mounts electronics.
• Swim platform: the low platform at the stern for water access, boarding the tender, and launching water toys.
• Beach club: on larger yachts, a fold-down area at water level at the stern, used as a lounge and launch point for toys.
• Bow thruster and stern thruster: sideways propellers that make docking far easier.

If you are comparing layouts, our flybridge yachts category is a good way to see how these decks come together on real models.

Interior parts of a yacht

Below deck and inside the superstructure, the living spaces have their own names.

• Salon: the main interior living and entertaining space, the equivalent of a living room.
• Galley: the kitchen.
• Head: the bathroom. A yacht may have several.
• Cabin or stateroom: a private sleeping room. The largest is usually the master or owner’s stateroom.
• Berth: a bed aboard, or a reserved space at a marina. Context tells you which.
• Bridge: the command center with navigation and controls, sometimes the same as the helm on smaller yachts.
• Helm: the steering station, where the wheel, throttles, and displays are located.
• Engine room: the space housing the engines, generators, and mechanical systems, often called the heart of the yacht.

Systems and equipment worth knowing

These terms come up constantly in listings and surveys, and they separate a basic boat from a true luxury yacht.

• Stabilizers: fins or gyroscopic systems, such as a Seakeeper, that reduce roll underway and at anchor. They are a major comfort feature and a strong selling point.
• Tender: the smaller boat carried aboard for getting to shore. It is stored in a tender garage or on deck.
• Davit: the crane used to lift the tender or water toys on and off.
• Generator: supplies power for air conditioning, appliances, and systems when away from shore power.
• Anchor and windlass: the anchor holds the yacht in place, and the windlass is the motorized winch that raises and lowers it.
• Propellers and drives: the blades and drive systems that convert engine power into movement.

Stabilizers in particular change the experience aboard. A yacht with modern gyro stabilization is noticeably more comfortable at anchor, which is why buyers prize it and why it appears so often in pre-owned yacht listings.

Why the right terminology matters when buying

Knowing these parts is practical when you start shopping. Listings assume you understand the vocabulary, a marine survey report is written in it, and crew communicate with it. When you can read a spec sheet and picture the flybridge, beach club, draft, and stabilization, you compare yachts far more accurately. It also helps during the buying process, where understanding what a surveyor flags on the hull, systems, and machinery can save you a great deal.

The same vocabulary scales all the way up. The difference between a yacht, a superyacht, and the largest vessels afloat is mostly size and the number of these features, as our guide to super, mega and giga yachts explains.

Frequently Asked Questions

What are the main parts of a yacht?

The main parts are the bow (front), stern (back), hull (body), deck (walking surface), helm (steering station), salon (main living area), galley (kitchen), head (bathroom), cabins or staterooms (sleeping quarters), and the flybridge (upper deck). Port is the left side and starboard is the right.

What is the front and back of a yacht called?

The front is the bow and the back is the stern. Moving toward the bow is going forward, and moving toward the stern is going aft.

What is the difference between port and starboard?

Port is the left side of the yacht and starboard is the right side, both judged when you face forward toward the bow. These fixed terms avoid the confusion of left and right, which change depending on which way a person is facing.

What is a flybridge on a yacht?

A flybridge is an upper deck above the main cabin, usually with a second helm station, seating, and often a sunpad or bar. It is a popular feature on cruising yachts because it offers excellent views and extra entertaining space.

What is the kitchen and bathroom called on a yacht?

The kitchen is called the galley and the bathroom is called the head. A larger yacht will often have several heads, usually one for each stateroom.
