On 18th April 2012, the delivery and naming ceremony of the new SWATH hydrographic survey vessel “Jakob Prei” took place at the shipyard Abeking & Rasmussen Schiffs- und Yachtwerft Aktiengesellschaft inGermany. The godmother of the vessel was Woman of the Year2011 in Estonia, Mrs Tea Varrak, who is Director for Innovation and Business Centre at Tallinn University of Technology.

The Estonian Maritime Administration ordered a modern SWATH-type survey vessel within the framework of the project “Enhancing Maritime Safety on Estonian Waterways (Procuring a Survey Vessel for Hydrographic Surveys of Waterways)”. The vessel is going to be named “Jakob Prei” in honour of Colonel Prei, one of the founders of the hydrography service in Estoniain the 1920s.

The 25m SWATH@A&R offers accommodation and common rooms for eight persons and will feature a containerized installation for research equipment. Therefore, a flexible adaptation to further development of instrumentation can be done with low effort in short time by changing the container.

Including this order Abeking & Rasmussen has meanwhile delivered or contracted 22 SWATH vessels for customers worldwide, which prove their leadership in this sophisticated technology. The total for 17 untis ordered makes the 25m vessels the most successful SWATH vessels in the world.

As an example of a SWATH hull, this hydrographic survey vessel from Abeking & Rasmussen is a good solid example of the design, constructed of aluminium.

SWINGE DESIGN'S SWATH HOUSEBOAT

This all aluminium vessel utilitises a Small Waterplane Area Twin Hull or SWATH. The discrete hull design ultilises an underwater submerged twin hull configuration to improve stability, in turn producing an aesthetically pleasing, elevated superstructure that is by no means aerodynamically efficient - but striking for it. The concept is though clean, and by that we mean angular, where angular is not particularly conducive to reduced drag (Cd), but then this is a house-boat, that is about the size of a house..

The houseboat superstructure stays out of the water to reduce cold penetration and water noise as bonuses for a peaceful cruising experience. The supporting legs have square leading and trailing edges, but we must assume that that would not be the case when proceeding from concept to developed design. There appear to be no energy harvesting devices, that absence of which in a modern age, should perhaps be addressed. Access is via hydraulic ramp at the stern of the vessel.

This is an interesting design exercise by Jonathan Schwinge BA Hons AA Dipl. RIBA. Johnathan was a scholarship diploma student at the Architectural Association - School of Architecture in London. He has worked for various commercial companies, including Nic Bailey Naval Architects and Designers, Foster and Partners and Allies and Morrison Architects - London, where projects included: BBC Media Village - White City, The Royal Festival Hall refurbishment, Bankside 123, Bishopsgate Tower - City of London, Paradise Street shopping complex, Kings Cross Station amongst many others. Schwinge Ltd was set up in 2005 to further inventive architectural designs that are technology driven - drawing influences from Space, Aviation and Marine designs. Other extreme designs include the Trinity Terahedron motor yacht
