List of longest wooden ships

Finding the world's longest wooden ship is not straightforward since there are several contenders, depending on which definitions are used.

Some of the more recent large ships were never able or intended to leave their berths, and function as floating museums.

Finally, not all of the claims to the title of the world's longest wooden ship are credible or verifiable.

The most used measure in length for registering a ship is the "length of the topmost deck"—the "length on deck" (LOD)—'measured from leading edge of stem post to trailing edge of stern post on deck level' or the "length between perpendiculars" (LPP, LBP)—'measured from leading edge of stem post to trailing edge of stern post in the construction waterline (CWL)'.

In this method of measuring bowsprit including jibboom and out-board part of spanker boom if any have both no effect on the ship's length.
