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. Marine-grade aluminium alloys such as 5083 are critical in achieving the necessary low weight to reduce drag at higher speeds. 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 lng-powered HSC Francisco (Hull 069, on Río de la Plata for Buquebus) is the world's fastest ship in commercial service and can achieve speeds up to 58 knots (107 km/h; 67 mph).
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.

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 more economically undertaken by water. Several fast catamarans have been built to transfer both crews and cargo for this market including Incat Hull 074 Muslim Magomayev delivered in 2015. The size of catamarans that can be built for this niche market is restricted by the 16.5-metre width of locks on the Volga–Don Canal that connects the Caspian Sea with the Black Sea and the Mediterranean.
Brooke Street Pier
From 1990 Incat had almost exclusively built large catamarans, but this changed in 2014 when the company diversified into something that was not even a ship, although it did float. An earlier Brooke Street Pier ferry terminal on Hobart's waterfront needed replacement and Incat was commissioned to build an 80 x 20-metre floating pontoon. Hull 077 was towed eight kilometres from Incat's shipyard to Sullivans Cove before finishing work was done on site. In addition to ferry berths, the pier hosts a restaurant, a cafe and a number of stalls.
Luxury super yachts
The market for opulent motor yachts has grown rapidly in the 21st century and while the market is mostly for monohull vessels, catamarans are beginning to make inroads. Incat has released several designs ranging from 80 to 112 metres which are shown on their website.
