the recovery of the market for large vehicle carrying ferries, Incat Tasmania's workforce expanded rapidly from 2015. Products Large wave piercing passenger and vehicle ferries In 1990 Incat was one of the pioneers of large, fast catamaran ferries and they have been its core product ever since. The type of ship was different from earlier ferries and its instant success led to Incat becoming a major player in the industry. Over the years innovation has led to the ships becoming bigger, faster, more fuel efficient and much more stable on rough seas. Vehicle decks are often movable to make way for high trucks or extra cars. Ships in this category have been built from 74 to 130 metres long and from 3,000 to 13,000 gross tons. The 99-metre Francisco (Hull 069) is the world's fastest ship in commercial service and can achieve speeds up to 58 knots (107 kmh). Smaller passenger ferries Incat began by building small ferries under 37 metres, but from 1990 it concentrated on larger vehicle carrying catamarans. However, in 2015 the company resumed building smaller ferries and in that year it delivered river ferries for operation in London, Hobart and Sydney. Since then it has designed and built more smaller ferries including two 35-metre, 400 passenger ferries (hulls 090 and 095) for commuter runs by Port Phillip Ferries from Melbourne Docklands to Portarlington and Geelong. Military vessels In the 1990s several catamarans built by Incat entered naval service as fast transports, including HMAS Jervis Bay with the Royal Australian Navy and HSV-X1Joint Venture, Spearhead and HSV-2 Swift, which served with the United States Armed Forces. Other vessels K Class In the mid 1990s Incat built three K class ferries. They are 70 to 80 metres long, low profile passenger vessels without wave piercing bows or the distinctive centre bow that characterise all other larger Incat ferries. Two were built by Incat in Hobart and a third was built by a Chinese partner. Plans for further Chinese built K Class ferries did not eventuate and Hull NF08 remains the only Incat vessel not built in Hobart. Oil rig tender Most offshore oil rigs are exposed to rough open seas with crew transfers by helicopter and freight needs served by platform supply vessels. However Azerbaijan's offshore oil rigs are in the calmer waters of the Caspian Sea, the world's largest lake, so crew transfers can be comfortably and
