Quantity: length

Isn't it better to use length (P2043) with qualifier of (P642) ? You just need to create items for the well-described maritime terms below. --Vladimir Alexiev (talk) 16:08, 14 January 2021 (UTC)

Hello Vladimir Alexiev , see here a discussion about properties for sailboat dimensions. --Simon.letort (talk) 11:43, 3 May 2021 (UTC)

length overall

   Under discussion

Description	length overall (Q2358152) : Length overall (LOA, o/a, o.a. or oa): is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking of the ship. It is the most commonly used way of expressing the size of a boat, and is also used for calculating the cost of a marina berth.

length at waterline (LWL)

   Under discussion

Description	(LWL): length at waterline (LWL, lwl, w/l, w.l. or wl.). It denotes the length of the vessel at the point where it sits in the water. It excludes the total length of the boat, such as features that are out of the water. Most boats rise outwards at the bow and stern, so a boat may be quite a bit longer than its waterline length. In a ship with such raked stems, naturally the waterline length changes as the draft of the ship changes, therefore it is measured from a defined loaded condition.

displacement

   Under discussion

Description	Displacement, in tons. A ship's displacement or displacement tonnage is the weight of the water that a ship displaces when it is floating; the term is defined ordinarily such that the ship's fuel tanks are full and all stores are aboard.

standard displacement

   Under discussion

Description	Standard displacement, in tons. The standard displacement, also known as Washington displacement, is a term defined by the Washington Naval Treaty of 1922.[10] It is defined as the displacement of the ship complete, fully manned, engined, and equipped ready for sea, including all armament and ammunition, equipment, outfit, provisions and fresh water for crew, miscellaneous stores, and implements of every description that are intended to be carried in war, but without fuel or reserve boiler feed water on board.

deadweight tonnage

   Under discussion

Description	Deadweight tonnage (DWT). A measure of how much weight a ship is carrying or can safely carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. The term is often used to specify a ship's maximum permissible deadweight, the DWT when the ship is fully loaded so that its Plimsoll line is at the point of submersion, although it may also denote the actual DWT of a ship not loaded to capacity.

gross register tonnage

   Under discussion

Description	Gross register tonnage (GRT), in register tons: a ship's total internal volume expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m3). It is calculated from the total permanently enclosed capacity of the vessel.

net register tonnage

   Under discussion

Description	net register tonnage (NRT), in register tons. A ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m3). It is calculated by reducing non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage.
