A navigational channel, usually marked by port-and-starboard lateral buoys and always shown on nautical charts, which leads in and out of a harbour – the equivalent of a road in coastal waters.

A soft, squishy air-filled bumper for use in harbour. Fenders are hung over the sides of a yacht to stop the hull from bashing or scraping against the dock or quay.
A docking manoeuvre used in rivers and tidal waters. By precisely balancing a yacht's heading and speed while motoring into the tide or current, a yacht can be made to 'ferry glide' sideways.
The distance of open water between you and the nearest land, in an upwind direction. Fetch is important because it determines the sea state. In simplistic terms: the longer the fetch, the bigger the waves.

Additionally, harbor masters play a crucial role in emergency response situations, maintaining navigational aids, and facilitating the smooth operation of maritime activities within their jurisdiction.
A motorcruiser with an enclosed salon and no flybridge – but usually a nice big sunroof.
Waves hitting the yacht head-on. Progress against a head sea will be slow and probably uncomfortable.

Inboard performance system – a highly efficient type of forward-facing propeller invented and marketed by Volvo.
A yacht designed to cruise in polar regions where it's likely to encounter sea ice and may have to navigate through pack ice. To be an ice class yacht, it must meet the hull strength specifications of a classification society such as DNV GL.

A jetty is a structure, typically made of wood, concrete, or metal, that extends from the shore into a body of water. Jetties are constructed to control the flow of currents and sediment and to protect the coastline from erosion. They often serve as a landing place for boats and yachts, providing a secure and sheltered area for docking.

Lines of latitude run parallel to the equator and are used to locate positions in the north-south direction.
A storage locker in the cockpit of a yacht.
A mooring system used in many non-tidal yacht harbours where the yachts are moored perpendicular to the quay, so-called because it's a lot easier than the traditional 'Med mooring' technique which relies on a yacht's own anchor. One end of the lazy line is attached to the quay, the other end is anchored to the bottom of the harbour roughly three boat lengths from the quay. To use it, you drive up to the quay, then pick up the lazy line with a boathook and walk it back to the stern of the yacht and tie it off there.
The wires that form a fence around the edge of a yacht's deck to prevent passengers falling into the sea. Also known as guardwires.

The Greenwich Meridian, located at the Royal Observatory in Greenwich, London, is universally recognized as the prime meridian of the world. It is designated as the starting point for measuring both eastern and western longitudes, and it serves as the reference point for the global coordinate system. The longitude of the Greenwich Meridian is 000 degrees.
In the realm of luxury yachts, a master suite, or owner's suite, refers to the most lavish and spacious cabin on the vessel. This suite is typically reserved for the principal occupant or owner and is designed to offer the utmost comfort and privacy. It often includes an expansive bedroom, a private bathroom, and sometimes additional amenities such as a private lounge, dressing area, or even a study.
A yacht mooring (parking) technique that's common in non or low tidal waters, especially in the Mediterranean. The yacht deploys an anchor or picks up a bowline and reverses up to the quay, where the crew tie its stern lines to a couple of bollards.

A powerboat is a type of boat or watercraft that is powered by an engine, usually an outboard, inboard, or stern-drive motor. Powerboats come in various sizes and designs, ranging from small recreational vessels to larger, high-speed boats designed for racing or cruising. They are popular for activities such as water sports, fishing, and leisurely cruising, offering speed and maneuverability on the water.
A platform that folds down and outwards to give an owner's suite or VIP cabin a private deck outside the yacht for swimming or relaxation.
A bed that folds up against the side of the hull, (or a bulkhead or cabin wall) when it's not in use.
This refers to four separate external layers of deck, and so is only found on large vessels.
A rigid inflatable boat, often referred to as an RIB, is a lightweight but durable boat with a solid, shaped hull and flexible inflatable tubes or collars around the sides. This design combines the stability and efficiency of a traditional hard-hulled boat with the buoyancy and impact-absorption capabilities of inflatable tubes.
A mooring (parking) technique that's often used in busy harbours. When there's no more room for yachts to tie up alongside the quay, they tie up to a yacht that's already there. In the most popular harbours it's not unheard of for a dozen yachts to raft up next to each other, which can cause stress when the yacht on the inside needs to leave at six o'clock in the morning.
A large, fixed, overhead shower, usually situated near the bathing platform or beach club.
A foredeck shape that's currently in vogue. It slopes down towards the bow, rather than up.
The chain or heavy-duty rope between a yacht and its anchor. Also called a cable.
A sacrificial strip added to the side of a yacht to reduce the likelihood of scuffing or scraping the topsides when coming alongside, going through a lock, using a box berth or rafting up. It's usually made of rubber or plastic, with older yachts using hardwood.
Running lights on a yacht are a set of lights that aid in making the vessel more visible to other boats or ships whilst underway and making way, during periods of reduced visibility, such as at night or in poor visibility.

They include red and green lights on the port and starboard side respectively, with an arc of 112.5 degrees; a white 'steaming' light for the forward arc of 225 degrees (112.5 degrees on the port side through dead ahead to 112.5 degrees on the starboard side for a total of 225 degrees forward), in addition to a white light on the stern, with an arc of 135 degrees.
Where the waves are passing from the aft (rear) of the yacht towards the bow. Care has to be taken to avoid surfing down the waves and turning the yacht with her side to the sea.
Seeman Composites Resin Infusion Moulding Process – a common boatbuilding technique used in hull construction. SCRIMP uses a vacuum to pull liquid resin into a dry lay-up material such as fibreglass or carbon fibre. Very similar to the generic term 'vacuum infusion'.
A Safety of Life at Sea (SOLAS) rescue tender refers to a specific type of tender that adheres to international maritime safety regulations. These tenders are designed and equipped to meet rigorous safety requirements, making them suitable for use in emergency situations and rescue operations at sea.

Semi Custom Yachts
A popular, general-purpose hull shape designed to perform efficiently at slow speeds, like a full displacement hull, and also at high speeds, like a planing hull. In truth, it's not quite as fuel-efficient as a full displacement hull and doesn't plane quite as well as a planing hull, but it does offer the best compromise between the two. Semi-displacement hulls also tend to be quite seaworthy. For more information read our guide Yacht hull types explained or search for a Semi-Displacement Yachts For Sale.
A shadow vessel, or support vessel, accompanies a larger yacht, providing additional storage, equipment, and logistical support. It serves as a practical solution for carrying tenders, water toys, helicopters, and other amenities that might not fit on the main yacht. The shadow vessel allows the primary yacht to maintain a sleek and uncluttered appearance while ensuring that all necessary equipment and recreational facilities are readily accessible to guests.
The classic motorboat drivetrain: a propeller shaft is joined to the engine's drive shaft at one end and the propeller is mounted on the other end. It passes through the hull via a waterproof stern gland and cutlass bearing.

Shaft Drive Engins
