The '''Subskimmer''' is a [[Diver Propulsion Vehicle|diver propulsion vehicle]] which is a form of [[rigid inflatable boat]] (RIB) with an outboard petrol (gasoline) engine. It is equipped to inflate and deflate itself as it runs. When submerged it seals its engine and runs with battery-electric thrusters, which are on a rotatable cross-arm, and is deflated. Thus it transforms between a fast light surface boat and a submerged diver propulsion vehicle. The central box contains the pump to deflate and inflate the tubes, and a miscellaneous kit. The batteries, being heavy, are in a thick tube along its keel. Its outboard motor has a long snorkel so the Subskimmer can run on motor just submerged to try to avoid detection. Its thrusters are on a rotatable cross-arm which contains navigation kit.{{citation needed|date=September 2017}}

The Subskimmer project was started in the late 1970s by [[Submarine Products Ltd]]. of [[Hexham]] in [[Northumberland]] in [[England]], the first boats being sold in their original form in 1983/84.{{citation needed|date=September 2017}}

There are 3 photographs of a working Subskimmer demonstrated in [[Portsmouth]], in the 15 September 1983 edition of the ''[[Daily Telegraph]]'' newspaper; the caption states its range as {{convert|6|mi|km}} at {{convert|2|kn|km/h}} underwater and {{convert|100|nmi|km}} at {{convert|20|kn|km/h}} on the surface. Submarine Products Ltd also built an orange search and rescue version of Subskimmer called Seasearcher with high intensity submersible spotlights fitted.{{citation needed|date=September 2017}}

When Submarine Products Ltd closed down, Subskimmer (as at 1989) was made by Defence Boats Ltd, based in [[Hexham]].{{citation needed|date=September 2017}}

At December 1992 it was being made (renamed Kraken 90) by Serrico, who were based at [[Saint-Georges-du-Vièvre]] in [[Normandy]] in France.{{citation needed|date=September 2017}}

In 1993 KSA (Underwater) Ltd in [[Alston, Cumbria|Alston]] in [[Cumbria]], England bought all rights to the Subskimmer.<ref name=":0">{{Cite web|title = Fast on water.|via=Free Online Library|url = http://www.thefreelibrary.com/Fast+on+water.-a0173229618|last1=Withington |first1=Thomas|work= Armada International |date=1 December 2007|access-date = 2016-02-08}}</ref><ref>{{cite web |url=http://www.armadainternational.com/05-6/complete_05-6.pdf |title=Getting it Done|access-date=2008-02-08 |url-status=dead |archive-url=https://web.archive.org/web/20070203222344/http://www.armadainternational.com/05-6/complete_05-6.pdf |archive-date=2007-02-03 }}</ref> KSA (Underwater) Ltd gave some marketing rights to Alpha Champ Marine Products Ltd, who defaulted on payment for the rights and all agreements with them subsequently lapsed. Alpha Champ Marine Products Ltd ceased to trade in 2007 and was dissolved in 2009.{{citation needed|date=September 2017}}

In 2009, Special Products division of Marine Specialised Technology Limited bought KSA (Underwater) Ltd along with all rights to its product range including Subtug and Subskimmer Submersible Craft, and moved all production to its manufacturing facility in Liverpool where it already designs and manufactures surface craft for military and commercial applications.{{citation needed|date=September 2017}}

As of December 2014, it appears that Subskimmers are being made in Indonesia for its armed forces.<ref name="weliyadi">{{cite web|url=http://weliyadi.wordpress.com/2010/11/15/sub-skimmer-karya-anak-bangsa-speedboat-ini-mampu-menyelam/ |language=id |title=Sub Skimmer Karya Anak Bangsa, Speedboat Ini Mampu Menyelam |date=15 November 2010 |work=weliyadi.wordpress.com |access-date=2017-09-10}}</ref>
