List of longest wooden ships
A list of the world's longest wooden ships is compiled below. The vessels are sorted by ship length including bowsprit, if known.
Finding the world's longest wooden ship is not straightforward since there are several contenders, depending on which definitions are used. For example, some of these ships benefited from substantial iron or even steel components since the flexing of wood members can lead to significant leaking as the wood members become longer. Some of these ships were not very seaworthy, and a few sank either immediately after launch or soon thereafter. 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.
A further problem is that especially wooden ships have more than one "length". 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. The largest length for comparing ships, the total "overall" length (LOA) based on sparred length, should be given if known.
The longest wooden ship ever built, the six-masted New England gaff schooner Wyoming, had a "total length" of 137 metres (449 ft) (measured from tip of jib boom (30 metres) to tip of spanker boom (27 metres)) and a "length on deck" of 107 m (351 ft). The 30 m (98 ft)-difference is due to her extremely long jib boom of 30 m (98 ft) her out-board length being 27 m (89 ft).
Longest known wooden ships
(50 ft 1 in)
|Wyoming||1909–1924||sunk||This American ship had a tendency to flex in heavy seas, causing the long planks to twist and buckle. This allowed sea water into the hold, which had to be pumped out. The overall length including jibboom was 450 feet (140 m).|
(59 ft 1 in)
|Bretagne||1855–1879||Decommissioned and broken up||The 120-gun Bretagne of the French Navy was the largest wooden ship of the line ever launched. The overall length of 120 m, from the tip of her flying jib-boom to the aftmost end of her mizzen driver boom, is extrapolated from the ship's official plans; her length of 81 m (266 ft) feet long on the deck fractionally surpassed the Royal Navy's 260 ft (79 m) HMS Victoria. However, Bretagne was not considered a particularly successful design, and was almost immediately rendered obsolete by the emergence of the ironclad, so in 1864 she had her steam engines removed and was relegated to training duties.|
|USS Dunderberg||1865–1874||scrapped||This ship was an iron-clad ship built in New York City, originally intended for the United States Navy during the American Civil War, but eventually bought by the French. About 50 feet (15 m) of her length was a ram. She was not particularly stable or seaworthy, even with her substantial metal components, and only made one voyage in the open ocean to reach her new owners.|
|Modern estimates are approx 104 m (341 feet)||20.3 m
|Caligula's Giant Ship||c. 37||foundation of lighthouse||Traces of this Roman barge were found during the construction of Rome's Leonardo da Vinci International Airport at Fiumicino, Italy, a port on Italy's coast, just north of Ostia at the mouth of the Tiber. According to Pliny, this or a similar ship was used to transport the obelisk in St. Peter's Square from Egypt on the orders of Roman emperor Caligula.|
|Pretoria||1900–1905||sunk||An American barge built for use on the Great Lakes. To strengthen the wooden frame and hull, builders included steel keelson plates, chords, arches, and also was diagonally strapped with steel. A donkey engine powered a pump to keep the interior dry.|
|Great Republic||1853–1872||abandoned leaking, sank||This American ship used iron bolts, and reinforced with steel, including ninety 36 foot 4x1 inch cross braces, and metal keelsons. The MIT Museum noted that: "With this behemoth, McKay had pushed wooden ship construction to its practical limits.". The overall length including jibboom was 400 ft (120 m).|
|HMS Orlando and HMS Mersey||1858–1871, 1858–1875 respectively||sold as scrap||These British warships were pushing the limits of what was possible in wooden ship construction and suffered structural problems. The overall length of approximately 335 ft (102 m) is apparently that of the hull from figurehead to taffrail – their length on deck was around 300 ft (91 m), while their total length from the tip of their flying jibboom to the aftmost point of their mizzen driver boom would have been somewhat longer, surpassing the largest ships of the line such as HMS Victoria and the French Bretagne (see above).|
(50 ft 1 in)
|Belyana type||19th century||disassembled||Belyanas were Russian river going ships purposely build for log driving on the Volga and Vetluga rivers. Their bottom was made from fir and sidings from pine and featured a complement of 60 to 80 workers.

|Santiago||1899–1918||swamped in gale and sunk||An American schooner-barge on the Great Lakes, towed by the Appomattox until 1905 and then the steamer John F. Morrow until 1918.|
|Roanoke||1892–1905||sunk after having burnt down to the waterline||A huge four-masted barque with skysails of a total length of 360 ft (110 m) and 3,539 GRT. In 1905 she was under the command of Capt. Jabez A. Amesbury when she caught fire while loading at the anchorage of Noumea. The crew, aided by those of the four-masted barque Susquehanna of the same owner and the three-masted ship Arabia, all in all 60 men, tried to fight the fire. This American ship used iron bolts and steel reinforcements. She belonged to the fleet of Arthur Sewell & Co. of Bath, Maine and was the largest wooden ship (115 m / 377 ft LOA) after the Great Republic.|
|Appomattox||1896–1905||run aground and sunk||A Great Lakes steamship capable of carrying 3000 tons of bulk cargo. Built with metallic cross bracing, keelson plates, and multiple arches because of her extreme length. Several syphons and steam-driven pumps were required to keep her afloat. Towed the steamer barge Santiago.|
|Baron of Renfrew||1825-1825||stranded and broke apart; planned to be disassembled to sell components||This unseaworthy British ship was a disposable ship. Created to avoid taxes on timber, the components were intended to be sold after the ship's arrival from Quebec to London.

The ship had 5,294 GRT and an overall length of 362 ft / 110 metres.|
|Frank O'Connor||1892–1919||burned||A steam screw operating on the Great Lakes, it required an innovative iron and steel-reinforced hull to be a viable vessel.|
|Columbus||1824–1825||broke apart and sunk||It was the first timber ship or disposable ship with a kind of four-masted barque rigging – just three square sails (course, top, and topgallant sails) per mast, two fore and aft sails on the spanker mast, and two foresails. Built to avoid taxes on timber (the timber used for the ship was tax-free), her cargo and components were intended to be sold after the ship's arrival from Quebec (Anse-du-Fort) to London. Changing its plans Charles Woods, her builder and owner, had only the cargo discharged and sold and ordered the ship back for another voyage with a timber cargo before being disassembled. But the ship broke apart and sunk in the Channel on her return voyage to Saint John, New Brunswick. The ship had a 356 ft / 108 metres overall length.|
|Shenandoah||1890–1915||converted into a tow coal barge in 1910, she was rammed and sunk by the steamer Powhattan near Fire Island, Long Island, New York on 1915 October 26||Another huge four-masted barque of the fleet of Arthur Sewell & Co. of Bath, Maine, with double top-sails, single topgallant sails, royal and sky sails of a total length of 360 ft (110 m) and 3,406.78 GRT.

- It foundered in heavy seas in 1924 with loss of all hands.
- The twisting and bucking of the planks were caused by the Wyoming's extreme length and mostly wood construction, although it did include metal bracing and other metal components.
- Steam-driven pumps were installed and run constantly to keep the hold relatively dry.
- Although adequately seaworthy and capable of 12.8 kn (23.7 km/h) using her 1200hp steam engine, the freeboard of her lower-deck gunports was just 1.45 m (4.8 ft), her draught was an impractical 8.56 m (28.1 ft), and she failed to match the impressive performance of the two-deckers of the Napoléon class.

- Even the biggest of the 5,000-6,000-ton wooden battleships of the mid- to late 19th century and the 5,000-ton wooden motorships constructed in the United States during World War I did not exceed 340 feet (100 m) in length or 60 feet (18 m) in width. The longest of these ships, the Mersey-class frigates, were unsuccessful, and one, HMS Orlando, showed signs of structural failure after an 1863 voyage to the United States. The Orlando was scrapped in 1871 and the Mersey soon after. Both the Mersey-class frigates and the largest of the wooden battleships, the 121-gun Victoria class, required internal iron strapping to support the hull, as did many other ships of this kind. In short, the construction and use histories of these ships indicated that they were already pushing or had exceeded the practical limits for the size of wooden ships. (Asia's Undersea Archeology, Richard Gould, NOVA, PBS Television article).
- "Britain had built two long frigates in 1858 – HMS Mersey and HMS Orlando – the longest, largest and most powerful single-decked wooden fighting ships. Although only 335 feet (102 m) long, they suffered from the strain of their length, proving too weak to face a Ship of the line in close quarters." (HMS Warrior, h2g2, BBC Television)
