Westermoen Hydrofoil Industry Shipbuilding Founded 1961; 65 years ago (1961) Founder Toralf Westermoen Successor Westamarin Headquarters Mandal , Norway

**Westermoen Hydrofoil** was a [shipyard](/source/Shipyard) located in [Mandal](/source/Mandal%2C_Norway), [Norway](/source/Norway), which has specialized in high speed craft, and pioneered many designs.

The yard was established in 1961 by [Toralf Westermoen](/source/Toralf_Westermoen), who had also started [Westermoen Båtbyggeri og Mek Verksted](/source/Westermoen_B%C3%A5tbyggeri_og_Mek_Verksted). The yard began producing [hydrofoil](/source/Hydrofoil) craft under license from [Italian](/source/Italy) [Supramar](https://en.wikipedia.org/w/index.php?title=Supramar&action=edit&redlink=1).

The first boat, *Westfoil*, with a top speed of 38 knots, was finished in 1962 and was delivered to the [Bahamas](/source/Bahamas). After that, a number of small and large (models PT20 and PT50) hydrofoils were built for passenger traffic in [western Norway](/source/Vestlandet), in the [Oslofjord](/source/Oslofjord), [Øresund](/source/%C3%98resund), Bahamas and in [Greece](/source/Greece).

Towards the end of the 1960 they built the world's then-largest hydrofoil, the "Expressen", that could carry 250 passengers. The boat did not achieve the intended design speed of 38 knots, and the contract was annulled. This was the beginning of the end of the hydrofoil epoch in Mandal.

After this, development of a new class of high speed vessel, the [catamaran](/source/Catamaran), began. The [Westamaran](/source/Westamaran) type, constructed by commander Harald Henriksen and introduced in 1973,[1] was very successful, and a new era of high speed craft in Norway and elsewhere was begun.[2]

Towards the end of the 1980s the yard changed name to [Westamarin](/source/Westamarin). Westamarin closed in the end of the 1990s.

One of the final ships produced was a single [High-speed Sea Service](/source/High-speed_Sea_Service) [HSS 900](/source/High-speed_Sea_Service#HSS_900) catamaran for [Stena Line](/source/Stena_Line) in 1997. The shipyard went [bankrupt](/source/Bankrupt) shortly afterwards, leading to [Stena Line](/source/Stena_Line) being unable to claim compensation for corrosion later found to the [aluminium](/source/Aluminium) alloy hull on the vessel (*Stena Carisma*).
