Equipment

Main Engines:The mains are one of the SUMMER WINDs best features. They are the original engines -- Cooper-Bessemer Model EN-6. They are very large, very heavy, and very slow-turning, with cruise power coming at about 400RPM!. This makes them very clean-burning, environmentally friendly, and fuel efficient, burning less than 3 1/2 gal/hour per engine. The engines are mounted on 10”steel I-beams more than 20 feet long. They are also direct-reversing, meaning that reverse power is obtained by shutting the engines down and starting them in reverse. Cooper-Bessemer engines have a reputation for efficiency and longevity. They were used primarily on ships, powerplants, and locomotives. Some are still in use today to compress natural gas for natural gas pipelines. After buying out the entire parts stock of a major distributor, we have enough spare parts to completely rebuild both engines, although we are told this will likely never be necessary. These engines are extremely quiet and smooth, making the boat glide through the water silently and efficiently.

Engine Details:
Size: Six cylinder, 8”bore X 10” stroke, naturally aspirated, 3016 cubic inch displacement, 150 rated horsepower per engine
RPM Range: 500 max, 400 cruise, 100 idle
Operation: Direct air start, direct reversing accomplished by dual lobe camshafts. Automatic electro-pneumatic reversing system with backup manual system.
Fuel system: Common rail with untimed low and high pressure pumps and timed high-pressure injectors and spray nozzles for each cylinder
Oil and water: Fresh water cooled with heat exchangers; piston-driven oil and water pumps, remote oil sumps with 40gal capacity, crossfeed systems between engines
Exhaust system: Dry stack with large mufflers

Running Gear: Each engine drives a 44” bronze propeller via a 3 inch shaft. The propellers and shafts are well-protected by the keel and skeg (yes, the mark in the picture do mean that the rudder is 8 feet high!). The shafts have wear collars pressed onto them at each bearing.

Auxiliaries: The SUMMER WIND has two diesel auxiliaries, one 20KW Northern LIghts with sound shield, and one 25KW Perkins/GE. All equipment can operate off either generator. Both produce 208V 3 phase AC power as well as 240 and 120 VAC single phase.

Batteries, Chargers, and Inverters: Two 32V banks totaling 770 AH, and two 12V banks totaling 700 AH. Each bank is charged by redundant electric battery chargers. AC power is provided to the cabin and galley by a 2500W inverter and a 1500W inverter. Cabin lights are DC powered directly from the battery banks. At anchor, the SUMMER WIND’s generators need to run only about three hours per day, making for peaceful anchorages and happy neighbors.

Steering and Navigation: The SUMMER WIND’s primary steering system is traditional chain-and cable, with an auxiliary electric steering motor. A large gear and clutch system allows for reliable switching between manual and electric steering. An 8’tall rudder makes her very responsive, even at low speeds. Electronics include a Furuno 32M radar, 2 DSSC VHF’s, a 40W loudhailer, a Garmin GPS, a laptop computer with NOBELTEC 7.0 electronic navigation system and full suite of Pacific Northwest and Alaska charts, a COMNAV autopilot, a SI-TEX depth sounder, a wind and weather station, a 18” bronze searchlight, and the original large compass and binnacle. She is also equipped with a second full steering station on the flybridge.

Anchor Winch and ground tackle: Markey Machinery custom-built winch with 9HP electric motor lifting twin anchors, one with cable drum, 70’ of 3/4” chain and 500 ft of 5/8 cable; the other with 300’ of 3/4” chain.

Deck hardware: Six 18”bronze cleats mounted on ironbark bases. Two 32’high galvanized steel masts with monel and stainless steel guy wires; forward mast with crows nest

Tenders: 2006 Lund SSV-14 aluminum tender with 40HP outboard and console steering. 14’ 1960’s Prothero cedar lapstrake rowing dinghy

Fire Supression System: Two Flomax 8 160gpm fire pumps; port and starbord 1 1/2” fire hoses with nozzles, 300LB CO2 automatic engine room fire extinguisher system; smoke alarms and portable fire extinguishers throughout.
