58 MY Questions

[exsailor]

Although my goal has been a late model 53ED, I have looked at some very nice 1510 58 MY's on Yachtworld. Since I know some of you have this model and participate on this Forum, a couple of questions. With the engines in the same locations as the 53, what about the props? If they too are the same, how does the boat handle? What about in reverse? Any other handling issues?
Is a thruster desired? I feel that the 8V92 is a great engine .... any comments about this application?
Thanks for any feedback

The 3sr 58 ('74) with 12-71s is a breeze to handle with no thruster. Ive done some tight maneuvering and rarely need to use the throttles. I do wish the rudders were about 25-50% bigger in area tho... ws

Sanctuary, which is a 58, is a pussycat. Heavy, with a keel, and props big enough to move her around with no throttle. With only a few trips out on her, she makes me look good when I approach a dock, or have to deal with close quarters maneuvering. I honestly don't see a need for thrusters on this boat, unless perhaps, you're live in a place with a very strong cross-current when docking.

The marina manager, who moved her for a storm once, said she had the nicest manners of any boat in the marina.

We've not had her out of the inlet yet, but I'm going to go out on a limb based on physics and a narrow beam, to say that without stabalizers, I'm expecting her to roll a bit in beam seas. We plan to avoid that when possible!

the 8v92 has it's quirks, like the wet liners, if you even come close to an overheat, you can lose the seals and coolant will wind up in the oil, which will quickly wreck an engine. The high HP versions don't live particularly long if run hard. If you run them modestly at the 1900 rpm continuous duty rpm, and keep the coolers cleaned out to prevent overheating they will last a long time. I put them in my boat and have always been partial to the 92 series. In my opinion the 8v92 is better suited for 50' and smaller boats, you could use them in the 58 if you run slower speeds, but the 58 is a heavy boat and I think the 12 cylinder engines would be better suited for that application. if you plan on running hull speeds then any engine would be ok, but if you plan to turn it up then you need the larger engines. Boats are severe duty applications and a boat places large demands upon our engines. My boat weighs 48,000 lbs the 58 weighs around 80,000 lbs and the later model 58s top speed with the 8v92 650 hp was only 18 knots wot, cruise is much slower. Most have to run at 2100 rpm to keep it on plane, but If you run it past 1900 for extended periods you are asking for trouble. Anyone with a 58 want to jump in and shed some light on this one?

Is a sub total displacement?? Surface running at 1600 gives 12mph on the gps.
Hardly on plane, but when yer chasin' fresh water tuna, and the canyon is out at the breakwall, speed doesnt mean a thing ws

That's interesting that you say that. I have always thought that most of the motoryachts that Hatteras built had very small rudders. I agree with your assessment, Bill.

But as far as a thruster goes, I see no need for one. My ED handles great without one.

 

[Boss Lady]

I tend to agree with Bill about the small rudders too. But we shall see how they do at the faster speeds Boss Lady will be doing when she goes back in the water.

 

[yachtsmanbill]

Rudder size has a direct bearing on a boat with "way on". Steerage and speed go hand in hand though. For maneuvering I still like to lay the rudders over for that additional 10% advantage. The fresh water tuna start running in May up here

 

[Boss Lady]

for slow speed the bigger rudders would be nice, plus you can do some tricks with them when docking.

Bill, insert photo of SS United States rudder here....three stories tall, actually had machinery etc inside it, plus electrical and plumbing...and probably not the biggest one built by far.

I think the 36Cs rudders are too small for good low-speed maneuvering. At speed she responds promptly, but not with lightning speed. I suspect they could easily be larger and work better. As far as low speed goes, I have never been able to walk the boat sidewise despite diligent attempts for years.

From everything I've heard (getting back on topic) the 58 is a very good handling boat- admittedly this is not a neutral group here, but we do tend to readily acknowledge the warts as well as the beauty spots.

Wheres the rudder pix? I always liked climbing around in stuff like that, and engine crank cases and hydrogen cooled generators. Theres a couple of cool barge unloaders (HULETTS) here on the river that are now on the historic landmark list. The operator would ride up and down with the load in a cab in the bucket.
