Brand new DEaster

[JLo]

Just bought a 1997 38 Duffy with 650 Mack and am new to this sight and DE boats. Still own a 29 Blackfin (my second one) and the new Duffy is head and shoulders above it. I have been suprised at how few 38 Duffys are out there and also hard to find any posts on the 650 Mack. I am told the 38 didn't sell well because the 42' was introduced at about the same time and only cost about 1,000.00 more so it was a logical upgrade to most buyers. The Mack seems to perform extremely well, giving me an honest 18-20 knot cruise with 6 people on board and a fair amount of gear and 3/4 full of fuel (300 gallons or so). It also appears to be miserly on fuel as well, although I haven't calculated exactly. Does anyone have any comments on the scarcity of this hull and motor and any suggestions on things I should look for or be wary of? Look forward to any comments or suggestions any of you may have. I am soooo happy I have converted from deep V to DE!

I had the Mack E9, 900HP, great engine but parts for the marine side were not around. That was I think the E7, great engine, everyone I know loves it, got to be great in that hull. We had to buy an exhaust manifold at one point and they told us it was the last one in stock, ouch...

So far I am loving it. I am certain it is at sub 20 gal/hr and has a wot of 24-25the knots. I see you are from the Cape. This boat will be staying in Chatham.

Pictures man, pictures! Congrats on your new boat.

650 Mack

Hook up on "boatdiesel.com". They have sites for every diesel with forums that have questions and answers by people who know what they are talking about.
Good luck with the new boat.

Congrats! Frigate on here has a 38 with a 800 cat. He can answer a lot of your questions.

 

[JLo]

Thanks for that. I will try to catch up with Frigatte for his input. I will also post pics as soon as I get a hold of my wife's camera.

Where in Chatham are you keeping her?

Any comments on the headsea ride of the boat? That's the only downside I've heard to this hull, need to pull back a bit more than you might expect for a built down hull. Other than that it's a huge 38', I saw one next to a 35' on the Cape this summer and the 38' could easily swallow the 35'.

She will be staying in Stage Harbor mostly. Only experience so far with head sea was coming out of Cape Cod Canal on bay side with a stiff NE wind and coming tide. It was NASTY. Ran the boat at 1500 RPM and never looked at speed...I would guess 12-14 knots. Got water over the bow once, never felt unsafe and seemed to handle it impressively well. Not a real test, though. This was a guzzel and I need to see it in open water.

I had a 38 osmond beal with a Mack E7 engine was bought from Manchester Mack in Manchester NH they no longer sell marine engines due to the fact that m
Mack saw how many marine engines they were selling and wanted to give it a try. Didn't make it to long. They no longer sell marine Mack's !
The first people to sell them was Daytona Mack ( I think that was the name )
They were in Fla. I'm not sure if they closed there doors or not .
I do know parts are becoming hard to get.
Get some photos up!!!!!!!
Keep us posted

I have that same engine in my 40' H and H. So far so good, but they like to drink fuel.

E7macks

Had a pair of E7's in our 44 Henriques for year before repose ring with cats. The Macks's were solid engines, but getting parts was the issue. Ours were marinized by Daytona. No frills all mechanical work horses but boy did they hate the smallest bit of air in the fuel.

Whatta Catch, So far I am finding this motor to be miserly on fuel, sub 20 gph at 18-20 knots. Maybe I am spoiled by the gas my 29 Blackfin drinks. Are you getting worse than that?

 

[Whatta Catch]

I have a flow scan, and actually just rechecked all my numbers this past weekend. At 1650 im doing 16kts and burning about 19 gph. On a overnight Canyon trip with 550 fuel 1,000 pounds of ice, At least 10 flats of bait, 8 cans of chum 3 bushel of clams and all tackle with 5 guys. I run her at 1800-1850 and cruise at 17-18kts but burn 25-26gph on the way home she burns about 24gph.

Boat is out of the water now and getting some work done to it to make it more fish friendly. I have very little time on the boat, maybe 12 hrs or so, but when I launch her in the spring I will keep track of her performance and get it to you. My motor was marinized by McDevitts out of Manchester, NH. Bill McDevitt has been helpful on the motor info and so far the engine/boat combo has performed jst as he said it would.

HOW WAS THE RIDE IN THE 38. I AM LOOKING INTO A 40 OB & trying to compare to a 37 Duffy in terms of capabilty.

 

[Muscie]

how do you like your 40' H & H. I am trying to get some feed back on the pros/ cons/ ride in various sea conditions . I love the space.

 

[JLo]

My boat is a 38 Duffy so I am not sure how it compares to a 37 Duffy...not sure that they even made one, but the boat handled a rough head sea, tight chop, extremely well, and a quartering 3-5 foot sea no problem. I have not yet done a following sea, but from what I've heard, they take it well. From what I have seen so far with this boat I would take it offshore in nasty conditions and not blink an eye. My other boat is a 29 Blackfin, known for its seaworthyness, and I don't think it holds a candle to this boat. My 2 cents (and I love my Blackfin!).

So far we love it. It is a Beast. All summer when we are offshore we have to head to th N/W to get home and with the southerly every afternoon we usually have a following sea. I put the auto pilot on and just sit back. I haven't had a real bad head sea yet that pounded her. Maybe the worst was 5-7'. It's not the fastest downeaster out there, but one of the most comfortable ones I was ever on. But my other boat is a 31' JC and it's a night and day ride. If it's blowing 20 N/W we are going.

hanks. Enjoy your new boat sonunds great
