At coordinates 40.87754°N and 73.76577°W, you will find Columbia Island; a 150-square-foot-dollop of rock off of New Rochelle, NY in Long Island Sound that is situated between David’s Island and Pea Island. In fact, prior to 1940, it was known as Little Pea. That was when CBS purchased it, and in 1940 began construction of a concrete foundation to support a transmitter building with emergency housing for ten workers, topped by a 410 foot (125 m) antenna tower for WCBS-AM (then known by the call sign WABC). The transmitter remained in operation until the 1960s, when the station was moved to nearby High Island.

Fast forward to today with the romantic notion of living on one’s very own island added into the mix as filmmaker and actor Al Sutton has been preparing to do just that on Columbia Island.There was a hitch, though. The tiny island with its well-known history, had no power or water. That’s where Florida’s St. Petersburg-based Mastry Engine Center stepped in and helped make it possible for Sutton to live there completely off the grid.

Sutton is renovating the facility that housed the aforementioned Columbia Broadcasting’s 410′ radio tower for almost 20 years. Columbia Island is essentially a 75′ x 75′ concrete building protected by a 175′ x 175′ seawall. Employees once lived there, using a well that has since been breached with seawater, and electricity from an underwater power cable that’s now long gone. Sutton’s goal is to create an off-the-grid, green home in this facility.

The Mastry Engine Center was a key player in meeting this challenge, supplying two custom-built, synchronized, 45 kW MasPower generators as part of the home’s power system. The packages feature electronically controlled Yanmar diesel engines, powder-coated enclosures, stainless steel exhaust systems and 100-gallon stainless steel fuel tanks. A DeepSea electronic controller is instrumental in synchronizing the generators; no easy feat on smaller power systems.he house’s 100,000W power demand is fed primarily by a 1,200 sq. foot solar panel array linked to six large Xantrex inverter systems, with overflow sent to a bank of 48V batteries. When needed, the inverters signal the MasPower generators to start, which then simultaneously supply house power while recharging the battery bank. As power levels stabilize, one generator shuts down, leaving one to finish charging the batteries.

Total Electric, a Charleston, South Carolina, alternative power specialist, coordinated the electrical system. To connect the MasPower generators, “All I did was plug and play,” said Total Electric’s Tom Stoudenmier. “Mastry was great, they did all the synchronizing and fine tuning of the circuitry that makes the generators talk to each other.”

The house itself presents its own obstacles. More a bunker than an island estate, its basement is consumed by four half-million-pound concrete pads that once secured the radio tower. To install the generators, Mastry completely disassembled them to fit through a hole cut in the floor, then reassembled and installed them within the sparse basement area.

Project manager Harry Hunt of Marine-Solutions, a Glen Cove, New York-based marine repair and restoration company, said renovation work at Columbia Island, “Is like working on a boat that doesn’t move.  This is a very small, unprotected island. Everything must be watertight to stand up to the elements.  It demands the use of the best available products.”

Water comes from a 1,200 gpd Village Marine reverse osmosis seawater desalinator. Waterproof marine bulkhead doors, hurricane-proof windows, roll-down exterior shutters and two 10,000 gph sump pumps help protect the house from the elements. Sutton is currently creating a documentary about the resurrection of Columbia Island and incorporating its unique history as well.

Mastry Engine Center, celebrating its 50th anniversary, specializes in marine and industrial engines for OEM and repower, use MasPower diesel generators and industrial equipment.

Originally designed for the rigors of commercial salmon fishing in Pacific Canada, the EdgeWater 228CCD is a workhorse.  It’s also the first diesel powerboat model for EdgeWater, using a fuel-efficient Yanmar 4BY2 180 hp engine from Mastry Engine Center.

“While we’ve traditionally featured outboard power, the 228CCD evolved from a custom gas sterndrive project for a British Columbia fishing lodge,” said Peter Truslow, EdgeWater Power Boats president.  “It made us think about alternative power choices, and opportunities for superior fuel efficiency.”

Having worked with Mastry Engine Center on other custom projects, Truslow again turned to Mastry and Yanmar for the 228CCD.  “We trust Mastry and have a great comfort level with them,” he said.  “Many of our dealers worldwide say Yanmar is the preferred diesel engine.”

The Edgewater 228CCD features a rugged profile powered by a Yanmar 4BY2 180-hp diesel engine from Mastry Engine Center

The end result is a surprisingly balanced 22′ center console jackshaft setup with ample cockpit and transom space.  With the console slightly farther forward, the 180 hp Yanmar is centered and low, behind a 75-gallon fuel tank.  The Yanmar 4BY2 is a 4-cylinder, direct injection, turbocharged, common rail diesel.  Performance on the EdgeWater 228CCD is a respectable 3.96 mpg at 35.6 mph @4,150 rpm, averaging 4.49 mpg in the 22-35 mph range.

The 180-hp Yamaha 4BY2 is an efficient yet powerful engine for the Edgewater 228CCD.

“Yanmar’s diesel engine is really smooth and very quiet, with amazing range,” said Truslow.  “What shocked people is the boat’s fantastic balance.  It floats just right, with the center of gravity lower and farther forward.”

The 228CCD uses EdgeWater’s Single Piece Infusion (SPI) manufacturing process.  Vinylester resin is vacuum-infused into both the grid structures and deep-V hull laminate in one step, making the entire hull bond as one.  SPI makes EdgeWater boats stronger and lighter.  “This complements the dynamics of a modern diesel engine,” said Truslow.  “The Yanmar works really well with SPI─they’re a perfect fit.”

Exposure at EdgeWater’s recent dealer meeting and the formal product launch at the 2012 Miami Boat Show validated the diesel concept.  “The 228CCD is about simplicity and fuel efficiency,” said Truslow.

“There is a niche of people who want EdgeWater styling, and are already fans of the dependability, durability and fuel efficiency of diesels.  But we’ve also found a new market of larger boat owners who, due to gas prices, want something simpler to run around in.  We’ve built many custom boats, and the 228CCD is an entryway to explore concepts for other fuel-efficient models.”

The EdgeWater 228CCD combines a spacious, fishing-friendly layout with superior rough water handling.  Seating includes a comfortable leaning post with storage below and aft-facing seat above the engine.  An unobstructed transom and full-width swim platform appeal to fishermen and SCUBA divers.

Customers can opt for a full bench seat across the transom, a T-top with rod holders and other accessories.  Information about the 228CCD and EdgeWater’s quality line of powerboats is available at

Mastry Engine Center of St. Petersburg, Florida, provides diesel and gas power solutions to marine and industrial OEM and re-power markets.  It supports a network of over 140 authorized dealers in the US and Caribbean.
