This ship, built by the Abeking and Rasmussen Shipyard in Lemwerder, Germany, is the A&R SWASH Explorer – a new type of workboat tender. SWASH stands for “Small Waterline Area Single Hull” as the deck and superstructure of the vessel ride above a single, submerged torpedo shaped hull connected by two foil shaped struts. SWASH (like SWATH) design places the bulk of the ships displacement below the surface of the water resulting in a low center of gravity which minimizes hull cross section at the waters surface. This results in less reaction to wave energy and maximizes the vessels stability even in high seas and at high speed. Along with the single lower hull, there are also two vertical outriggers on either side of the superstructure which work in combination with a fin stabilizer system to balance the 12m wide vessel. These outriggers also provide convenient flat surfaces for docking.
The single submerged hull tube contains all the ship’s systems including the main engine, gears, shaft, generators and bow thruster plant. The use of a single hull minimizes weight which results in greater efficiency for smaller ships and in less noise. At this time, A&R is targeting the new small SWASH design towards pilot groups, wind parks, police, customs and local authorities.
