Taza Mas, a 93 ft steel ketch, approached Marine Maintenance Services (BVI) with a challenge. She had 2 old Onan generators that were old & limping & needed replacing.
After reviewing all the options the owner decided to replace them with 2 new M864 25kw Northern Lights. This was a particular challenge as the old generators had been installed by cutting holes in the side of the hull & inserting the units, re-welding afterwards. After copious measurements we decided that the old units could be removed & new generators installed by walking them through the boat. This involved lifting under the aft covered cockpit roof, 20ft through the upper salon, down a flight of stairs, around a corner, down another flight of stairs then monkey swinging both units into place. Nothing like a challenge!
Both generators are now installed & purring away to the great satisfaction of the Captain.
