Page 20. MAINE COASTAL NEWS December 2011 CATERPILLAR LAUNCHES NEW MARINE ENGINE - C175


Cat C175 Designed to Drive More Profitable Vessel designs.


Caterpillar introduced the Cat C175-16 marine propulsion engine at a size, power and rpm that will drive new, more profitable vessel designs for all segments of the marine industry. The latest in a line of high performance engines designed to meet EPA Marine Tier 3 and IMO Tier II emissions requirements, the C175-16 is rated at 2001 – 2168 bkW @ 1600 rpm and 2239 bkW - 2550 bkW @ 1800 rpm. The new propulsion engine extends Caterpillar Marine’s high- speed engine power range beyond the company’s already industry-leading 3516C- HD engine.


The C175 engine is already being offered in non-road applications to meet EPA Tier 4 requirements. Ideal for offshore support vessels, tugs, and workboat applications, the C175-16 features technology advancements and updates to ensure maximum productivity and minimal environmental impact. “The C175 marine propulsion engine has been designed to improve total vessel profitability by providing durability with unmatched power output to ensure our customers can maximize


profit in their offshore and commercial operations. It is the new industry standard in terms of hard-working, revenue-producing power,” said Bob Hallengren, Caterpillar Marine Power Systems product director. “Naval architects can design vessels around the Cat C175 engines with the confidence these engines will deliver in terms of power and load carrying capability.”


The C175-16 utilizes proven ACERTTM Technology. Cat ACERT engines feature optimized turbocharging and aftercooling to provide reliable maximum power output. Efficient combustion reduces engine wear and maximizes fuel, driving the C175-16 to pull the maximum amount of energy from each injection event. The engine also features the Cat common rail fuel system enabling low emissions at all levels and requires no aftertreatment to comply with regulations. In addition to a 1,000-hour oil change interval, thermo-laminated heat shields save time and money during service. All factory-packaged components are supported by Caterpillar warranty. “This engine is a great choice for vessel owners and designers who want to gain greater productivity from their vessels while

something else wrapped up on the propeller. This saved the owner of the vessel hundreds of dollars because it could be done in the water and not on a railway. It also got him information on where there were wrecks. As time went on people asked Luther if he would lecture on what he was finding. He was also doing underwater photography and this made his lectures much more interesting. He added, “We weren’t doing well with the bulbs. They would implode if you took them too deep. A lot of times they wouldn’t go off. I was lecturing about shipwrecks, and I showed some of the underwater pictures that I had taken. They didn’t come out with the true color. Dr. Edgerton looked me up after the lecture and said you want to try my strobe. I had no idea what that was. He said you go down and see one of my students and he knows all about the strobe and he can build you a nice case for one. It opened up a whole new world, and it worked beautiful. Now we could get crystal-clear pictures of fish with- out worrying about them moving and the colours were true. Edgerton came up to me after one of my lectures and he said can you help me out with something else? He said, ‘I have invented a penetrator and it shows you a profile of what is down into the bottom. I found that if I turned it sideways it found a sub profile of the bottom and that means shipwrecks. I wonder whether you could take me out to some of them, let me find them with the machine and then tell me if I am right in assuming that the bow was up here and the stern is down there, she’s laying on her side or she’s laying upper right or upside down.’ I said. ‘I would be more than happy to.’ Eventually he came and asked me if there was some wreck that was of historical importance that would be good enough for him to find with the side scan sonar. I said, ‘Yeah, the Vineyard Sound Lightship disappeared in the ‘44 hurricane with all hands and nobody knows where it went. We took him out to the site and within 15 minutes he had found an image that was big enough to be the lightship. The measurements pretty well corre- sponded, but he says I can’t say for sure that this is the lightship. I went down, landed right on the stern and went up to the bow where there was a big mushroom and the hawse pipe right in the bow. That’s a lightship. We


significantly minimizing their environmental impact,” said John Shock, Caterpillar Marine Power Systems offshore segment manager. “The new C175-16 features a number of enhancements that will improve overall engine life while reducing the cost of ownership.”


With a bore of 175 mm (6.9 in) and a stroke of 220 mm (8.66 in), the C175-16 is highly efficient while providing increased propulsion output in a high speed engine platform. Additional features include:


Turbocharged and aftercooled aspiration; MCS approved monitoring, alarm, and protection system; Cross-flow head design; and Simplified electrical system. The new C175-16 is backed by a Caterpillar warranty and the best service network in the industry. The global Cat dealer network means customers can count on the service and support they need for their marine engines no matter where their vessel is located.

proved that what had sunk her was the big spare mushroom, housed upside down on the gunwale on the starboard side, had got loose and swung right through the bow plate. Edgerton used this as publicity for MIT and his invention of the side scan sonar.” There are a lot of wrecks scattered all over the New England coast; some with har- rowing tales others not so interesting, but all offer the wreck diver the opportunity to find souvenirs.


I remember one summer back in junior high school going with him on dive on the North Shore of Massachusetts. He did a dive in Gloucester harbor and then out by the breakwater off Rockport. He said the one by the breakwater was likely the granite schoo- ner ROBERT RICH. She came out of Rockport and ended up on the breakwater and scat- tered her cargo all over the bottom. There was also a freighter on the Dry Salvages that was used as a bombing target that he would investigate.


Another interesting wreck is the ship-of- the-line NEW HAMPSHIRE. She had been built for the War of 1812, but was not finished for more than 40 years at Portsmouth Naval Shipyard in Kittery. She was a full-rigged ship and had been used as a floating barracks, training ship and prison. During the mid- 1920s they wanted to do a full restoration on the USS CONSTITUTION and decided to take the NEW HAMPSHIRE around as a fundraiser. As they were towing her she got caught in a northeaster and went ashore off Manchester-by-the-Sea. Luther said, “There isn’t much left because they sent a crew down there from Revere Copper & Brass to raise all of the pieces and get out the spikes. These spikes were made at the Revere foundry. For their big centennial, or whatever it was, they wanted those spikes and give them to their preferred customers. However, they lost the barge coming down to New Bedford. They went back and searched, but never did find it.”


There are numerous great wrecks along the North Shore. Luther documented numer- ous ones and searched for as many as time would allow. Now with the price of side-scan sonar much more affordable, more wrecks are coming to light. If you are looking for a great hobby, love diving, and love history, you can not find a better pastime.

eight or nine years old and engines were just coming in and he knew how to run them and his father didn’t. A little later he started put- ting cabins on boats for people and pro- gressed from there. He went to Grand Manan and was there for a couple of years. Beals and Grand Manan, the Wesleyan Church, always had something going. Will Frost was looking for assistance, and some thought he should meet this woman on Beals so they brought him over. Guy Carver, Sr. brought him over in a barrel, because he was illegal. He met up with my Aunt Nella and they got married in 1928. They lived for a time in Jonesport while he worked for Frost until he had financial issues and headed to the west’ard. Harold began building on Mouse Island, but after a while they purchased some land on the west


side of Beals built a house and moved the shop in front of it on the shore.


Dodge said, “Uncle Harold started out on that island building rowboats and peapods. In ‘36 he started a boat for Elmer Alley. His first lobster boat was 32 by 8½. He built boats right up until he died in 1972. That Sunday night he called and said everything was fine and he died they figured about four o’clock Monday morning in his sleep. He was quite a guy. He wasn’t very big, probably only 5-5 with a big bald head and big hands. Slow working one pace, but he always got the job done.”


Dodge hopes to have the current boat in his shop done for the races. However he has a 36-footer that he started in November. He did not race last year because he was too busy with his new one. So we are hoping to see this one at Jonesport!
