RE: 1 engine or 2?

Seems to me having two engines increases the chance of fouling them several fold over a single.* Want/need that protective keel.

RE: 1 engine or 2?

You can spend anywhere from 500k to 2million for a Krogen or Nordhavn with a single engine.* It is not about whether money is no object, it is about personal choice.

Maybe we should also debate, triple and quadruple engine vessels.* If one engine can fail can't two or more breakdown too?

Walt, I'm starting to have to rethink this whole situation.* I just didn't know how the psychology (I only took one course) plays into the single vs. twin engine thing.* Does twins with 1000hp mean that I have a large member or is it a 3 cyl. single engine?**Does the large twin engines mean that I am insecure?* Eric, help me out here.* You seem to have given it some thought.** Or ......*am I conflicted because I have*both a twin and a single screw boat?* I'm really needing some kind of guidance!***

1 engine or 2?

for me the safest thing to have connect on my motor is a pyrometer( exhaust temperature gauge).
When this thing go on ... it is not to late, generally you could fix the problem.I have one install on my main and the other one on my genset.
This was the first thing that i install on my boat.

RE: 1 engine or 2?

Nomadwilly, my bow thruster comment was meant to be in jest. It harkens back to a thread that disclosed some opinions that there is something wrong with using a thruster . I think they are handy. I use mine when ever I need to. Before I REALLY need to.

In the single vs twin debate, will all probably favor what we have. It is a big factor in deciding which boat we finally bought.

*Walt, the Sabre is twin 500hp Yanmars.* The Blackfin is a single 3208 turbo Cat.* Just having some fun at Eric's expense I guess.* Just thought it was an interestig theory.* I have also owned a 34 Mainship Pilot single with a bow thruster.* Loved it.* To further complicate my quandry, the Sabre has twins and a bow thruster.*

Charlie,

Having no more info to go on than your original post, I'd say that you might be a twin guy. I, personally, prefer single, but I was new to it and didn't need the extra expense. Plus, I am just cruising the ICW for the foreseeable future, so a the so-called "get home" engine is unnecessary. Besides, one good motor is plenty for me. However, we don't know much about you. What is your experience? What is you budget? There are too many questions.

RE: 1 engine or 2?

Well guys I hope we all had fun. fedex caught me off guard and I'm w him. At least I would be if I had a thruster or two. I'd use it lots. Most everybody seems to be happy w what they have**** ....no surprise as they/we bought what we bought. I seem to be a weird dude w a single and preferring a twin. I'm in situations where I feel the redundancy of the twin would clearly be the thing to have. When we came up here in 06 we came out of Slingsby Channel and turned north along the coast in front of and by Cape Caution w 25 knot onshore winds. We did that just after a leak in the cooling system was discovered and repaired that probably would have shut us down. Right then and there I would have loved to have had a twin. No doubt about it. I had'nt thought of it as a major issue in the twin/single debate but on reflection Walts point about what kind of boating one does is indeed a major issue. In the last single v/s twin debate I don't think it was brought up. So if you had a twin Walt I'd trade ya boats. Would be nice if it had a FB though. Mike, now that I've seen the trailing edge of your keel my opinion of the DeFever just went up ...* more than a notch.* Sure wish my Willard's keel looked like that. ************************************************** ************************************************** ***

There are quite a few new folks on TF that have just purchased boats.

Perhaps they can give you some insight as to what influenced their decision.*** KJ

*A true trawler in the 40-45 ft range is easily powered by a single normally aspirated engine many with a track record of excellent service. With proper service the likely hood*of a surprise engine failure is very small and in my opinion well worth the risk, even in the Bahamas. The extra cost and maintenance of another engine just makes the negative aspects (more work) of boating more apparent. Regardless I would carry an EPIRB or other reliable communication device when boating in isolated areas, regardless of one or 2 engines. If for nothing else, medical emergencies.*

But I think there are more issues to consider. When searching for a boat for me and my wife, I could not fine a trawler in our price range that my wife liked. Most where all beat to h*ll and I could hardly get her to look at them, ever though I felt there was potential. We finally settled on a go fast twin and I have no regrets. She loves going on the boat and that means more to me than anything else.*

I know this discussion is not about going fast or not, and having come from many years as a sailor I really thought a trawler would suit my needs. However now with the capability of going 15-20 knots our cruising area has expanded*exponentially. Our favorite anchorage is about 30 miles and just was not do able on a weekend when sailing. However now that and many other areas are easily cruised to on weekends with plenty of time at the anchorage. If you have all the time in the world, the go fast aspect is not as important of course, but just the capability of getting somewhere before sun set that you might not otherwise be able to do is comforting.*

Choice of engines is another important factor one that is not normally discussed. A normally aspirated Perkins or Ford Lehman even if somewhat abused is still pretty reliable. Not so with a high*performance*turbo charged diesel with raw water-cooling. I have two of these high*performance*diesels and though I can go like h*ll they can be*temperamental. They are reliable if properly maintained, but I don't think I would get a single engine boat with one of these engines.*

If you get a twin you do have the option of using just one engine. This has been discussed before on this forum:*http://www.trawlerforum.com/forum.spark?aBID=115492&topicID=38913265&p=3

My experience shows significant fuel savings though if you read the above thread not all agree. Some will argue why buy a twin if you cruise on one. My reply: Options; to save fuel if desired or get there fast if necessary.* Blocking of the shaft on the unused engine is necessary and probably more work that its worth, but to each his own.

Good luck on your search and let us know what you get.*

Mike, I think it is interesting how the twin engine hull appears to be ready for conversion to a single???!!!!! Just an observation.
