03 480 DB With MANs?

Gary, what do you think of 1200 hp mans in a 58' Viking? I was on a 87' at the waterline Fead sportfish this week it had twin 1500 c-30 s.

Exactly. Bigger engines will allow the boat to maybe accelerate faster, have a higher cruise and higher top end speed but at the end of the day...

And smoke more getting up on plane. With larger wheels On the higher hp diesel it's fun getting through the 1200rpm to 1450rpm range before the turbos kick in...especially more fun if you have to come off plane in an inlet, and then try to get back on plane to counter eight foot brakers :wow:

The reality is I can cruise at 26 knots if there is 1' or less... anything over that and the throttles come back quickly... ocean travel and lower bay travel is usually 23 knots... (2-3 feet)... anything over 3 feet and I'm quickly down around 16-18 knots... These boats are no Vikings...


Can the Vikings comfortably take much more? I thought about chartering a Viking or similar 50-58 foot sportfish just to see how they handle the waves. I have friends with an older early 90's 58 Viking SF (smuch slower boat compared to the newer ones) and in rough seas they didn't seem to do much better. Never the less this has peaked my curiosity lately.
 
I've driven a 63 foot Viking Sport Cruiser with MAN engines... don't remember the model of the engines... it was a really great ride... if you have a cool $3M to dump down on a boat. The only Viking convertible I've driven was a 48' with MAN engines... it was a real battle wagon in the water but the thing burned 95 GPH... no thanks.

The Viking convertibles can... they have an entry like a razor blade on the front. I'll be slopping around on the bay in 4-5 foot waves and they'll just blow right by me... bastards...
 
Mike I love Searay too, but come into reality. Your boat would go down in minutes compared to 50-58 Viking built for the ocean in some of the crap those boats venture out in.
 
While I have never ran a 480 DB with anything but Cats in it, I have run a few Vikings that were MAN or Detroit equipped.

On lake Michigan our waves are very steep and close together and the best riding boat to date that I have run was a 1996 54 Viking Sport Yacht with 800 MAN's, the aft cabin looking model not the sport cruiser. This boat CRUSHED 5-6 waves with no effort, never pounded, and didn't skip a beat at 27 Knots.

The other boat was a 47 Convertible and it was pretty much the same experience but the boat pounded on occasion however very minimal compared to some other boats I have run.

The closest boat I would have to compare to a 480 DB would be an 05 500 DB with the QSM-11's that I actually had a deposit on in 2007. I backed out for personal reasons but the boat ran beautifully in 3-4's that I had it out in. I am assuming that the 480 runs pretty similar since its basically the same hull?

Is that when the four foot hydraulic swim platform tears off the transom? :grin:

I just want to know if their shower doors creek while at speed in heavy seas, or if it's only my boat.
 
WOW - How did I miss this thread!

OK, so I have this boat but of course as Gary said mine is 3 years newer, I have a 2006 52DB, D2876 LE 405 Engines. I am not sure if those are the same exact engines, but mine are not common rail, and they do smoke a little, but not much.

All of the comments here are pretty accurate. I do love my MAN's...

1. You have to find out who can / will service it - They have a limited service network, and I think you need someone who knows MAN's
2. Parts are expensive and sometimes hard to get
3. The engines seems to be built VERY well
4. I cruise at about 26 - 28 knots at about 80% load.
5. At WOT 2300RPM I can get up to 32k on a calm day
6. At cruise, they burn about 50 gals an hour. I don't think that is that much more than Gary's (Gary please correct me if I am wrong here).
7. As far as rough handling, I agree the hull design is the hull design, bigger engines will not help. When it gets crappy, I have to slow down to 16 knots, or my crew and boat will probably fall apart.
8. You need to check on the number of hours and how much ($$$) the next service interval is, I am told that the 1000 hour service is EXPENSIVE!

I am very happy with my engines, and my MAN man has always taken good care of me, and is always there for any question I have. I would not hesitate to get the MAN's (unless there is no one to service them)

Thank you for the posts!

Ryan, that was very helpful to hear from somebody who owns a very similar boat.
