In September 2005, work started on the fit out and rigging of four Sunseeker XS Sport boats. The hulls had been built earlier that year. The last boat of this current production run is shown here.The Sunseeker XS hull is a race tested balsa-cored Kevlar® sandwich structure derived from the FB Design racing hulls, winner of many Offshore World Championships. The bow was developed from the racing experience of FB Design boats, all using anti-stuffing fins which enhance the seaworthiness by preventing the boat from nose diving in heavy seas. There are two models available - the Sunseeker XS Sport and the Sunseeker XS 2000. The main difference is that the Sunseeker XS 2000 has a small cuddy cabin and the Sunseeker XS Sport has a large seating area and front sun bed. Both have room for a toilet fitted under the centre console.

Early Sunseeker XS Sports were fitted with twin Yanmar 350hp diesel engines with a top speed of 56 knots. The Sunseeker XS 2000 has a twin Yanmar 420hp diesel engine installation. In this case, the top speed is about 65 knots. The Sunseeker XS 2000 was dropped from the Sunseeker range in 2005, although there are still some second-hand boats available. The Sunseeker XS Sport now comes with the option of twin 370hp or 440hp Yanmars . Sunseeker XS-IF is fitted with the 440 hp Yanmars and a top speed of 65 Konts summer, 67 Knots winter (nice cold air) and winter props on.

Both the Sunseeker XS Sport and Sunseeker XS 2000 are fitted with ZF two-speed transmissions which makes the boat very easy to manoeuvre (1.3:1 ratio in low gear, 1:1 in high). The transmissions drive TriMax surface drives fitted with Rolla stainless steel propellers. TriMax was developed by renowned Italian designer Fabio Buzzi and consists of a propshaft that runs from the transmissions straight out of the back of the boat. The TriMax surface drive system also allows the exhaust to exit the bottom of the boat just forward of the props. They also have outlets from on-deck air intakes to get more air around the propellers and so induce slip at low speeds. This means that the engines can gain rpm and horsepower more quickly. The TriMax system has the need for a false or secondary transom in order to accommodate a drive configuration that includes the rudders and large, long Buzzi-designed trim tabs. The only external elements are the tabs themselves, which tuck up into insets in the bottom of the boat. The hydraulic pumps and all other hardware are inboard, which makes them easy to maintain.
