SEA DIAMOND is powered by a pair of GM Detroit Diesel 6V71N naturally aspirated freshwater cooled 2stroke diesel main engines built on remanufactured long blocks. The main engines are rated for a reported 210hp at 2100 RPM.
The main engines are close coupled to Allison Marine reversing gears. There are no data plates on the reversing gears; however, documentation onboard indicates the final drive ratio of 2.05:1.
The main engines are single isolation mounted on the main longitudinal in the engine room. There are Kobelt hydraulic disc shaft brakes actuated by reversing gear clutch pressure. The output shafts pass through the aft bulkhead of the engine room and are sealed by a packing gland. Shafts run in pillow block type greased bearings and exit via steel stern tubes with Tides Marine type Strong dripless seals.
Each main engine is fit with a Parker Racor main engine crankcase recovery system. The main engines are 24volt DC start off dedicated battery banks. The battery banks are maintained by engine belt driven alternators or by dedicated 12volt DC battery charger located in the engine room. The port main engine PTO drives the stabilizer hydraulic pump. The starboard main engine belt drives a Lestek 24volt DC 240 amp alternator for the house battery bank system. Each main engine and reversing gear is plumbed with an oil change system quick connect. The main engine exhausts are dry stainless steel risers with hard coat insulation to water lift stainless steel mufflers with discharge out the transom. The exhaust connections are black exhaust rubber hose and fiberglass extension pipes with stainless steel hose clamps. The starboard main engine belt drives a manually clutched Jabsco impeller type emergency bilge pump with cross connect to the main bilge system. The main engine controls are Morse single lever with chain and cable arrangement. The main engines are each protected by a single Racor model #1000 fuel filter water separator with pressure/vacuum gauges. The main engines have local start/stop panels located in the engine room with bridge start disable and Murphy switch gauge package with alarms for main engine oil pressure, jacket water temperature, gearbox oil pressure, amps, tachometer, hours and raw water pump suction vacuum.
SEA DIAMOND is fit with a pair of Northern Lights naturally aspirated diesel electric generators single isolation mounted inside full factory sound shields. Each generator is 12volt DC start off dedicated 12volt DC batteries located adjacent to each generator. The generators belt drive 12volt DC alternators.

Forward are the hawse pipes fitted with chain wash. Extending down from the deck forward is a Samson post. Forward down the port side is the stainless steel hydraulic plumbing for the headstay roller. The anchor bins are lined with a hard plastic material.
Built by Abeking & Rasmussen and designed by Philip Rhodes you couldn’t ask for a better pedigree. SEA DIAMOND is very well known in yachting circles around the world. She is an exceptional vessel that has been well maintained by her very generous owners over the years. Between 2001 and 2004 SEA DIAMOND underwent a major interior and major systems refit at the cost of 6 million dollars. Her entire interior was completely stripped down to bare hull and a new interior was built from scratch. The work was performed at Fairhaven Shipyard, Fairhaven, MA over a 3 year period. A team of craftsman with nothing but the best wood working skills was assembled for the new interior joinery work. The end result was a beautiful masterpiece of wood work. At the same time, the entire teak deck and subdecking were replaced. Also during this refit period, complete new AC and DC electrical systems were installed, including all new pumps, air conditioning, and galley appliances. Two new 32 kw Northern Lights generators were installed just before this refit.
In 2009 all new Sitka Spruce masts and booms were built, along with all new custom fabricated metal mast hardware. In 2010 the entire interior was redecorated with all new fabrics and soft goods. The end result was stunning for a yacht of her age, better than the day she was built!
SEA DIAMOND is matchless. And although she has been reworked from a mere shell, her period piece quality has been retained. At the same time, she offers a full array of modern amenities and serves as the perfect hostess to the most discerning guest.
SEA DIAMOND always attracts a great deal of attention in harbors and anchorages everywhere.
