Seeking to purchase Cruising Vessel

My wife and I are quite interested in purchasing a new power boat
Desired specs: (however open to all):
- 40 foot +/-
- fuel miser, slow and steady 7-10 knot cruise
- prefer single screw, twin is expectable
- Lehman's preferred
- sun decks are fun
- full displacement trumps semi
- located in PNW unless owner wants to deliver it
- canvas, generator, water maker, current electronics are all big pluses
- must be glass, no wood vessels
- $60k to $130k, with $90k being the mark

Thanks to you all

Presumably you mean "new" only to you, with that budget.

Greetings,
Welcome aboard.

SGM, Is that your initials or Sergeant Major? Welcome to the forum. It sounds like you have your ducks in line. That's a reasonable budget, and you should be able to find a good vessel in that range. You'll probably even get some offers on here. Welcome aboard. Ben

That 10K desirement will mean over sized engines and big fuel bills FOREVER.

Perhaps a 36 ft LWL cruising at 7K might use 2/3 less fuel and work out better.

Delighted you chose Cruiser , as the desire rather than the usual trawler .

10K does not mean big fuel bills forever. One does not have to go at 10K all the time. Fuel miser and power boat are incompatible terms. At 3-5 NMPG none can be called miserly. In any event fuel will probably be the least expensive part of owning a boat unless you are constantly on the move.
Why limit to lehmans there are a lot of great modern 4 stroke engines out there.


My 1997 44' ACMY with twin 420 HP diesels gave about 3 NMPG at 7 knots but would also do 23 kTS. It sold for 130K in good shape.


Other than hull shape a lot of older Grand banks fit your specs and provide decent livability.
Older boats tend to have more teak requiring more maintenance than newer boats.


40' or a bit more is a great size for a cruising couple. And with the right boat provides great handling, slow or fast.

Having second thoughts of selling our hatteras but I would really like sail boating to Spain (hope my wife doesnt see this). Our 43 MY burns 3.5-4.0 gph at around 7 knots. Fuel burn has never been a deal breaker. Comfort and function has been tops for us. The aft enclosed (isenglass) sundeck has been great. The down side, its not easy to launch our dinghy. We got the hang of it though. There is always trade off's to any design. Check us out.

With a 10 it speed at 40ft you're looking at a semi displacement.

I don't think there is a full displacement boat in a Sundeck model. Someone correct me if I am wrong.

The purists would agree. However, Art DeFever didn't listen and designed an entire fleet of aft cabin vessels (some sun decks like the 44 - 50 line still made today) which he considered "close enough". Tolly's 43 is another aft cabin fitting the "close enough" mold.

Art's designs took into consideration the potential for lots of aft weight such as fish, tanks, charter vessel bodies casting for tuna and water. Canoe sterns, as some feel must be part of a FD design, do not like weight.

All this said, Tad Roberts some months ago correctly opined on the difficulties of labeling SD and FD designs into too narrow a box. Best I stay silent as he is an expert on this stuff.

Our hull needs a lot of power (WOT) to plane. Then I need to play with the trim tabs. The detroits have more HP than my cats so I just travel hull speed or less. I will say its more relaxing slower and less wind noise. I can plow through 3-4 footers on the nose with no problems. Beam seas create lots of roll though. The hatts are real heavy.

Stop selling unless you want to deliver it free of charge to the PNW.

A friend of mine has a boat like yours. It will gitty up and go, when you need to. The hatt isnt considered a full displacement hull but its pretty close. The props are exactly even with the depth of the keel.

So, just to try and clarify...

If you want to be miserly with fuel, you need to keep your speed at, or below, "hull speed." For a hull speed of 7 kts you need a boat with a length-waterline of a little over 27'. For a hull speed of 10 kts you need a boat with a length-waterline of more than 55'. Obviously a big, big difference.

If you are willing to travel around 7-8 kts most of the time, that should be no problem in a boat the size you are considering. For the occasional burst to 10 kts or above, just be aware that your fuel consumption is going to go up exponentially.
