T/S Royalist, 97’ Grove & Guttridge

T/S Royalist has contracted Marine Tech to carry out all of her annual engineering works for the past  4 years. Our 200-ton lift at Endeavour Quay and full engineering work shop facility is ideal during the vessel's very busy winter refit schedule. Over the years Marine Tech have completed top end overhauls of both main engines and generators. In 2008, we installed and commissioned a new Marpol approved sewage system.

Ishacoco, 44’ Sunseeker Carmargue

The owner of a 44’ Sunseeker Carmargue reported a small coolant leak at the front of the starboard main engine. During in-depth investigations our engineer discovered parts of the block casting in the sump. Cracks in the journals were later exposed and the engine was decommissioned immediately. We removed the Caterpillar 3208 engine for total rebuild including a new block.

S/Y Silvertip, 108’ Ed Dubois/ Yachting Developments

The 33m Ed Dubois yacht arrived at our Endeavour Quay facility in 2007 for a major refit. Marine Tech was involved with removing the entire hydraulic system, which was serviced and replaced. We also dismantled and removed her Hunderstad variable pitch unit to be sent back to the manufacturers for overhaul. The vessel was fitted with new generators and her main engine was overhauled.

M/Y Slip Stream, 62’ San Lorenzo

We lifted Slip Stream at our facility in Endeavour Quay. Slip Stream’s owner commissioned Marine Tech to fit a Willdo bow and stern thruster unit. The system works off water pressure generated centrally by a massive hydraulic water pump and controlled by 3-way valves forward and aft. To create the hydraulic pressure Marine Tech fitted a new Onan generator with a big hydraulic pump bolted to one end. The owner also contracted Marine Tech to rebuild both 750hp Detroit 8V92 main engines.

S/Y Twirlybird VI, 100’ Jongert

Twirlybird VI was the 6th super-yacht of a very experienced yachtsman and underwent a major refit in 2008. Marine Tech successfully repowered the vessel with a state-of-the-art electronically controlled Volvo Penta main engine. The owner also requested a variable pitch propeller, a type which he had fitted to previous Twirlybirds. The project included extending the engine room to fit the VPP unit and line-boring the stern tube to accept a much bigger shaft. Other projects included fitting and commissioning a Hamann sewage treatment plant and new Onan generator.
