Diesel Engine Choice?

I have this engine in my trawler and am very pleased with it so far. It
has 2200 hours and runs like a top. I switched it to Amsoil 15-40W
marine diesel oil run through a bypass filter and hope it will give me
20,000 hours. I run it between 1600 and 2000rpm and get about 3mpg. Ask
me when I'm even older and I'll tell you how it worked out.

Single screw? What sort of headway do you make at 2000 rpm?

You might want to go down to Chandler's Cove, see Dave Formo, and check
out a Camano Troll. Could resolve your speed vs economy dilema- at
least somewhat.

The layouts don't do much for me, but that may change based on
prevailing circumstances.

Trawlers are beamy but spend so much sq. footage on walkarounds that the
cabin ends up too narrow for my taste. That's why I like the sundeck
version. It too has its weaknesses, especially if it has no cockpit.

Right now I'm far less concerned about speed than efficiency. I'm
resolved to 8 kts if that's what it takes.

BTW, I hope you didn't take my response and question as disparaging or
tongue-in-cheek. I'm truly curious.

I never realized how enjoyable it can be. If a boat only does 7-8 knots,
you don't expect anything else and begin to enjoy the characteristics of
that particular boat. One of the most pleasant afternoons on the water last
year was a relaxing, full speed run on the GB. Took a couple of hours,
didn't go very far, only burned about 5 or 6 gallons of fuel, but it was
genuinely enjoyable being able to relax and take in the sights.

Single screw in a 36 Monk. It does about 9 knots at 2000 rpm, 8.5 at
1900 and a little over 8 at 1800, depending on how heavily I'm loaded.

I just did some research with Cummins and others to find out how slowly
the motor could be run for extended periods without problems. It's a
turbo and there are issues if the thing doesn't spool up fast enough and
heat up properly. i am told to go 1500 at a minimum, maybe 1600, but to
make sure it's running at the regular operating temperature.

I'm doing the Great Loop this year and the difference in operating costs
between getting 3 mpg and 3.5 mpg will buy a lot of beer.

Cool, thanks for the info. Having grown up with twins, I'm in awe of
those who dock their singles in tight spaces, especially the ones
without a thruster...
