Discovery is a 43ft bespoke catamaran designed for both diving and survey work, previously operating under MCA Cat. 2 (60 miles FSH) and is still owned by the original designer. She was built to the owner's exact requirements by Roach Boat builders at the Souters' Yard in Cowes in collaboration with the well known Nelson designers; TT Boat Designs. She has operated very successfully for diving and survey work associated with locating and discovery of shipwrecks and archaeological sites. She has been meticulously maintained and is still to this day a working boat. She is an exceptional vessel with functionality the key attribute. Discovery has a massive working area on both fore and aft flush decks. Her powerful Ford Sabre engines have only done 2870 hours. The boat is structurally in an excellent condition. She has been very well looked after and is maintained and refitted annually.
Should you want to view this great boat please contact Roy Heeley on O788 094 7376. If you are coming from the mainland we suggest you come by ferry from Lymington.

The large Wheelhouse/Desck Saloon is the central feature of this design, laid out with a central helm station with all instrumentation in a large console arrangement in close proximity to the helm chair. A crew seat is placed on starboard side and the panoramic view provides an excellent helm position. A large chart table is placed immediately to port of the helm station, with a large secondary chart table/survey desk behind the helm. On the port side aft of the wheelhouse is a large seating area with saloon table (telescopes down to make double berth) in an 'L' format returning to the aft central door exit to the after deck. A small Galley is located to starboard with stainless steel sink and H&C pressurised water. There is ample space for storage and the unit has a Flavel Vanessa gas cooker / oven. The sponsons on either side under the wheelhouse provide a total of four basic bunks at the lower level. The heads area is forward in the bow compartment with sea toilet (ITT Jabsco). The shower arrangement with H&C supply is aft of the wheelhouse.
The after deck area provides a massive working area for deploying survey or other equipment and easy access to the engine rooms and jet installations via large deck hatches. The raised gunwhales and rails provide safety right up to the foredeck. To starboard forward is situated a hauling derrick with adjacent 1.5 ton hydraulic capstan winch/hauler.
Access to the flybridge-deck is by stainless ladder mounted on the starboard aft of the wheelhouse. Secondary steering and engine controls are on the flying bridge. A substantial gantry mast arrangement houses the antennae for fitted equipment. Newly built large GRP storage boxes/lockers utilise the spare space on the flying bridge.
At the stern the Ultra 340 jet units (new 2008) are protected by cleverly designed platforms, the port side serving as the divers’ entry to the vessel with a fold down ladder fitted to the port after platform. The starboard side incorporates a removable 'prop wash' device which redirects the water jet output vertically downwards, for dredging or excavation work. The hull form has small skegs at the stern with a moderate keel depth for increased directional stability.
Twin FORD SABRE 350C turbo charged and intercooled 6 cylinder engines are connected to Ultra 340 water jets (jets new in 2008). Each engine delivers 350BHP combining to give 22 knots maximum speed, and cruising at 18 knots at 2200rpm (@14 psi. The installation is serviced at regular intervals, full details of which are available. The Kubota 35hp auxiliary engine in the forward port compartment drives all hydraulics for the vessel, winch and compressors, including a BAUER MARINER 7.5cfm high pressure compressor (for filling dive cylinders) and a HYDROVANE 47 LP compressor (high volume, low pressure air for airlifts or inflating lifting bags etc) installed under the port main deck adjacent to the Kubota.
I designed and had the vessel built incorporating all the ideas and equipment that my previous vessels lacked. Compressors and winch/capstan run hydraulically and below decks, independent of main engines, leaving massive amounts of deck space available. The large wheelhouse was designed to accommodate a large variety of survey equipment and the vessel is ideal for many uses. Even wind farm work is an option; it would be easy to fit a fender platform across the bow if needed. It is a perfect vessel for diving/hydrographic survey or diving charter (easy to fit a diver-lift platform). A lot of other advantages including stability, shallow draught which makes it easy to put ashore on the beach among many other advantages"
This is a very functional, very sturdy work boat, obviously designed and built by people who knew what they were doing and the job it would have to do and is still doing very successfully. To build this same boat today would cost 3 or 4 times the asking price.
