Europe does Full Displacement a lot better than the US ever did. This is a nice boat, forty-one feet, 105 HP DAF(tractor motor), tons of beautiful accommodation, go-anywhere steel construction, excellent deck layout.

The flat aft sections have a benefit at anchor as the boat has zero roll, rock solid . Many round bilge boats are very unstable at the dock and at anchor. This is not as noticed on a sailboat do the the weighted keel. I have a friend with a Nordhavn who uses flopper stoppers at anchor to control roll. This Hatteras design I would say is probably 90% full displacement. I have not ever driven this boat hard enough to experience squat in the stern. Hargrave stated the flat sections keep the boat from squatting. Maybe true but the boat hardly leaves a wake at 8kts. With 2 453's I cruise at 1800 or less. Mostly at 1600 which relates to 7.5 to 8 knts. This is 1.85 gph each This boat carry's a large beam of over 17' which doesn't help speed or economy. This is still about 2knt miles per gallon. Slow to 6knts and get about 3knt miles per gallon. Push it up to 10knts and get 1 knt mile per gallon.

And for that, you get the title of "Guru?" Maybe I should rethink the whole trawler thing.

The main benefit I see and feel with a FD is in large following sea condition. The SD hulls can get little more squirrelly when you are surfing down the face of a wave. This is when you need a to drag something behind the boat to help combat this or more power to out race the problem. Most boater never have worry about this because they would never be out in those conditions.

It's most amusing before they pull up to a marina and ask what their deals are and what's free.

OK, I should of worded that differently. I mean when they shakedown marinas trying to make deals and bend prices.

Deals are great but when you try bend already deals that being plain cheap, sorry should have worded that better for what I intended.

No, I think you made yourself perfectly clear. I know several well healed sailors who would take severe exception to your comment. And I doubt they would buy you a drink.

Yes in a following sea it's very soft and easy movement especially with stabilizers.

I have to agree that this has been my experience. one of the solutions is to stay on the back of a wave which put you in that ugly spot burning a lot of fuel.

I'm going with much closer to FD than SD. With that curved deadrise she's not going anywhere with more power. I do wish she was a bit deeper in the belly so I could go 100% for you

Thanks DaddyO- The builder in their brochure called it a SD. I believe that was spoken as the time of construction was the fuel crunch of the 70's it would sound better to infer a level of "speed". Not true in this case, as one person of knowledge of these hulls spoke. "They are abysmally slow!". Comfortable but slow. Just what I wanted.

and there are plenty of claims said about all power boat owners too. The truth is there is good & bad in all, both the boats and the owners.
Me - being a motorsailer owner - I try to walk the line and not fit into any category.

>The flat aft sections have a benefit at anchor as the boat has zero roll, rock solid<

All boats that are basically flat on the bottom will stay parallel to the water surface .

Dock side this is great as there is little movement when folks climb aboard.

The problems only come when the water surface is NOT flat.

Then the bottom will also stay parallel to the water surface and a 6-8 ft or larger waves abeam can create a very rough ride.

Not a hassle for most inshore operation, where even with high winds there is little fetch to create larger waves.

While the round bottom of a full disp boat will allow some motion at all times the difference is the entire hull is lifted by a wave , rather than the chine corner beginning to rapidly roll the boat.

There is also a huge difference in the way the roll stops as the wave passes under.

The slow soft check of the disp boat is far kinder than the hard check, almost snap of a boat with corners well immersed.

Watch a log go by in rougher water , it mostly just goes up & down , watch a floating box go by , it follows the rough water surface .

Boats are designed to operate in specific conditions , operating one in a condition it was not designed for can be uncomfortable.
