Seafast Don

The Seafast Don is a 23-metre lightweight aluminium catamaran providing a stable, flexible platform for geophysical survey campaigns.

Utilising an A-Frame (currently in progress), the Seafast Don will be capable of undertaking a full range of geophysical operations including Multibeam Echosounder, Side Scan Sonar, Sub Bottom Profiler and Magnetometer TVG.

The vessel can accommodate up to 12 passengers, with 12 suspension seats with armrests, headrests, and lap belts. The small bench seating and table provides for an adequate survey office. The vessel sound levels of 55 dB in the suspended wheelhouse also provide a comfortable level for working.

The vessel features a galley and mess room, a wet room and toilet, and lockers for personal belongings. The kitchen is equipped with a stainless steel sink, an electric cooker, a combination oven, and a fridge freezer.
