SWATH means Small Waterplane Area Twin Hull and is guarantor for excellent sea keeping behaviour.

The basis of this ship type was born in the 1960’s and 70’s when semi-submersible vessels were introduced to the offshore market. Naval architects developed these vessels further and it was used as navy test craft, pilot tender, yachts, passenger boats etc.

The German Shipyard Abeking & Rasmussen has more than 100 year of experience in innovative ships and designs. Since 1999 more than 20 SWATH vessels like pilot tender, pilot station vessel, explorer yacht, wind park maintenance tender, offshore patrol vessels and a hydrographical research vessel were built.

This paper should give an insight to the SWATH technology and the implementation in the market. Different applications and ideas will be shown. Whatever you need - a navy ship, a workboat, a multipurpose platform a ferry or a yacht – there are many possibilities.
