There is a 1984 Hatteras 61 Cockpit Motor Yacht with Cummins, 2009, QSL9-405 engines in Vero Beach, FL. Is this a good idea for a cruising boat?

Re: Hatteras 61 Cockpit Motor Yacht with Cummins engines?
With only 405hp that s a trawler. Economical? Sure. But it s not going to get on plane so only cruise speed is 9.5 kts
Depends on how you plan on using the boat.Pascal

I fail to see the logic in this. If you have a boat that size, your fuel cost is probably the smallest single item in your yearly expenditure on that size boat. Why would someone put a pair of tiny engines in a boat that size and make it sale-proof in the future?

Re: Hatteras 61 Cockpit Motor Yacht with Cummins engines?
It’s been listed for three years or more, I’m sure the owner is asking himself the same questions. I looked at her before buying our 63’ and passed. Since then, looking back, we could have done all of our travels in a smaller engined boat since the only time we went faster than hull speed was to warm up the big old engines. I would have missed the extra 2’ in the master stateroom and salon though. I did think she was a very nice boat in above average condition and we did make an offer on her which was not countered, so we looked elsewhere.
The big unknown is how she will be in a sea with so much weight removed from the engine rooms. There have been two threads about this in the past few years and I linked to them in another thread in the past month or so.Michael & Beth

Re: Hatteras 61 Cockpit Motor Yacht with Cummins engines?
It s not just the annual budget but the cost of the repower itself. Whether you put bigger or smaller engines, the labor costs, engine bed fabrication, etc are pretty much the same. Plus whatever else you’re going to do at the same time.
By the time you ve spent $150 to $200k in a repower, $30/40k more for bigger engines isn’t a big deal.Pascal

Re: Hatteras 61 Cockpit Motor Yacht with Cummins engines?
I agree. As you say, a big chunk of the cost of a repower (unless you put the identical engines back in, and that isn't done often) is the revision of the engine beds, wiring, plumbing, etc, for the new engines.
I suppose that people who repower a large boat with small engines figure that most people run them slowly, and that's maybe true. But other aspects come into it- the changes in weight and distribution, the reserve power for when you need it, and most of all the resale value. I think if you repower a boat that size with modern engines of the same power, the value will go up a bit- not what you have in the work, but some. And someone will want to buy it. But if you go small as in this boat, you may own it for life. Your life.
