Nordhavn 46

[Open-d]

BTW, as far as I recall, they are all Detroit powered

Mostly, some with 53-series engines.

Any thoughts on that series of engines?

 

[Open-d]

In general, they are great boats if the model fits your needs/desires.

In specific, they are no longer produced so the condition of the one you are considering is critical, like any other used boat out there.

We are roughly planning a 2-year "cruise", locale to be determined. As I understand it, and somebody/anybody correct me if I am wrong, they are solidly-built hulls, circa mid-70s.

Another question, I notice a fair number of trawlers in fresh water, often stored in boat-houses over-winter. Would the transport involved, both in terms of expense and any stresses and strains involved be worth getting a boat never in salt water?

Greetings,
Mr. O-d. Way to many variables in your questions to give a definitive answer.


Where and how you plan to cruise? Transporting from where to where? How much of a premium are you willing to pay for a "fresh water boat"?


As to the last point...A well maintained vessel used primarily in salt water could easily be in better condition than a poorly maintained one used solely in fresh water.

Assuming all other factors to be the same, and transport from the midwest to a coast.

Greetings,
Mr. O-d. I am not familiar enough with Nordhavn's to speculate IF they can be moved by any other means other than on their own bottoms or by freighter.

IF you're talking about another make, again, many variables come into play.

There are FL 120s in at least one 48LRC.

Great Lakes vessels can be run to NYC in 2 weeks if under 20’ in height. All else equal, I would MUCH prefer a freshwater boat from the Great Lakes or Western Rivers.

I've used 3 of the 4 in non marine applications but wasn't aware of Bosh...

Sunchaser,

I recently installed Keypower stabilizers on my Selene. The pump is a Bosch unit running off the Twin Disk gear. We also installed an oversized heat exchanger. Keypower fins require zero maintenance (no seals to replace) and operate with a pair of balanced hydraulic actuators which reduce stress on the overall system. Also, the firmware in the gyro and digital controller can be updated. Keypower is now owned by Kobelt Industries, well known for their hydraulics and steering systems on commercial vessels.

I am contemplating trawler-style or similar vessels in the high 40's or low 50's in length.

Assuming that the move is done correctly, and there are no "accidents", would that move generate any stresses or strains/damage to hull or etc., that would be damaging to the vessel's integrity/seaworthiness?

 

[Open-d]

Yes, in CA. Also one with 4-53s.

Any thoughts on that powerplant for use in displacement hull types such as trawlers or Hatteras LRCs?

I'm pretty sure Lugger is the dominant engine you find in the 46. The only Detroits I've seen used in Nordhavns is the Series 60 in boats 68' and above.

If you are talking about overland hauling, the biggest damage might be to your wallet!

The requirements for oversize permits vary from state to state, and sometimes there are even county requirements. The beam of the load will dictate if escorts are required (maybe even a police escort) and the height will dictate if a pole car is also required. In many states, oversize loads can also only be moved during the weekday between certain daylight hours. Once you reach a certain size, the OVERSIZE load becomes a SUPERSIZE load and is subject to even more requirements. Big dollars can add up pretty quickly.

Many times boats need to have their flybridges removed in order to facilitate transport.

My suggestion would be to contact a couple of well known boat haulers to get real world estimates on what a land move might cost for any boat you might be interested in.

All of the above makes overland hauling more difficult for larger boats. Thus, many folks would opt for on the water delivery and may hire and captain and crew for the task.

The relative ease of professional transport is one of the reasons that I'm leaning towards an express cruiser for my next boat.

To Open-d, if you're looking at a 40-50ft heavy LRC or "trawler" style boat, then it will likely be beamy and have a deep draft, big air draft as well. I doubt that you will find one of these in Lake Lanier or some other landlocked body of water. So you will sail it to where ever it needs to go.

What better way to learn about a new boat than on a long inland river. Your broker will know a good skipper who you can hire for a short time to cruise WITH you and teach you the new vessel. The length of time to hire him will depend on how much background you have in boating. I was a complete idiot when I took possession of my 65ft twin diesel. But I had a pro captain help me for a half day and it calmed my nerves, gave me direction and I was (most importantly) self-confident after that.

Hi all. Pictures is in a new album on my profile. Yesterday we did 6 knots on downwind quarter stern in 20 knots of wind.

Nice updates! That swim platform increased the waterline length quite a bit it looks like. Does the boat still like a following sea?

How much total sail area did you have up for that 6 knots? That’s pretty good performance under sail only for such a heavy boat!

If by saying “move” you mean over land, I don’t know. Moving vessels that size over land, outside of the boatyard environment, is not common. I would not consider this an option due to the reasons others have mentioned.

When I say “run” I mean on the water, underway. For example, you find a boat in Bayfield, WI...it can be in New York City in 2 weeks on its own bottom.

Janaconda,


Took a look at your album.. great boat you have there. Did you add the swim platform or was that a previous owner? Looks like she sails well.

Same caution as most Detroits , they MUST use CFII oil to live long and prosper.

Most require about 60%+ of rated power to be used for best fuel efficiency.

NEVER over heat them.

Main, Genoa and Mizzen. Yes the waterline is increased 4 feet.

Remember, your boat is not documented WITHOUT the +4 ft. That might make a difference when you use a marina in your travels.

Never use the words "Detroits" and "fuel efficiency" in the same sentence ! I doubt my old Grays were generating more than 16 or 17 hp per gallon.

"I doubt my old Grays were generating more than 16 or 17 hp per gallon."

Unless you went thru many props with a Flow Scan or electronics your current engines probably are the same in cruise.

The Mfg. tout 20 or 22 but its really hard to get.

 

[Okydowky]

Open-D, don’t take this wrong.
I re read the thread and I wonder do you have any boating experience? Or have you ever owned a boat?

Thanks to everyone’s input on this thread, there is a lot of good info on there for a good read.

I pulled up an old DD spec sheet with power curves and it indicated max efficiency of about 18.3 hp/g-hr
