Broker's Comments

This Ex Admiralty motor vessel is currently operating as a Survey Vessel with a Category 2 coding. She was refitted in 2009, and is equipped with modern Navigation and Communication systems. Her twin Detroit diesels and ancillary equipment have been fully maintained.
This vessel has the potential to be converted into a comfortable long range motor yacht, or alternatively could make a very spacious floating home. She has a diesel generator and 240 volt electrical system, including the galley. There is no gas system. Heating is supplied either be electric heaters or a diesel fired heating system.
She does require some cosmetic improvement, but having said that, she is at the moment a working vessel.
