Need to hear from owners of these yachts as to their reliability.
Reliability how? I've run several Princess yachts. Their gelcoat has a VERY nice shine to it, they ride fairly well, build quality is average or above average BUT definitely a step below Sunseeker in ride, performance, and build quality. When comparing UK boats.
The sliding door from the helm to the Saloon is a PIA to work on when the rollers fail or screws start coming up into the tracks.
Managed a 58 for a while with V12 MANS.
Skinny room between them. A/C pump & strainer was down between them. Another PIA to service.
Some additional breakers hidden behind the breaker panel. ie; A/C pump breaker.
Nice trim and fit. Ran well, level & straight in a sloppy chop.
Oh, Strange shaft and prop nuts. Looked normal but the nuts kept jamming and gnawing on removal. Squared end, metric thread.
We feel the metal in the shaft was strange and distorting threads between the two prop nuts.
Boat went back north several years ago and owner moved up.
I do miss her, fun to drive and the interior was finely done.
Brands have different characteristics over the years. Most haven't even been under the same ownership. It would really help if the OP would indicate what time period he's talking about and then poster's indicate the same.
Isn’t saying the Viking Princesses indicate a time period?
I have a 50 ft Viking Princess flybridge that I bought 9 years ago, and the boat was 9 years old when we bought her. We have taken the boat from the Chesapeake to S. Fl and back several times and at least 15 trips throughout the Bahamas. We have covered about 25,000 miles and typically spend 80 nights or more a year on the boat.
By now I have replaced most of the electronics due to age, the ice maker, one refrigerator, canvas and other consumables. Items like the auto pilot pump and ram or a leaking line on the upper helm steering pump were replaced, but most of these were done at the first sign of a leak or wear and were replaced proactively and has been a key to having a reliable boat.
I would say the boat has been very reliable and only one trip was messed up due to a failed fuel injection pump, so not really a problem due to Viking Princess. Key reliability points have been the electrical system. I find the entire circuit breaker layout and wiring to have been well organized and never had a single electrical problem other than I replaced the original main contactor when I first got the boat as it had a slight buzz that turned out to be from a 50 Hz breaker in a 60 Hz application, and has been silent since.
The plumbing is all Hans Grohe and is all original and nothing leaks. The port holes are all Trend and none of them have ever leaked. Things like windlass, AC systems, bow thruster, vacuflush etc. are all quality products and have been very reliable. I did have to replace the holding tank a few years ago.
My model allows access to all simple engine checks, fuel filters, and fluid changes directly from the engine room hatch. For anything more involved I easily role up the salon carpet and in 10 minutes the floor comes up for complete standup access to the engines. This is well engineered on my model.
I have had my props on and off many times and never had a problem with the nuts. I did lap the nuts and props so they seat properly and on my model a standard hardened shaft material was used. I did replace the rollers on my salon sliding glass window which was easy and has been flawless since (Viking had the replacement parts in stock). I did have my entire set of front windows resealed, but I think that is normal as a boat gets 15 plus years old.
Viking Sport Cruiser parts in New Jersey is very helpful and one of the reasons I went with this manufacturer. They will contact Princess, get factory drawings, have access to the build sheets and have a nice stock of model specific parts.
Regarding ride, I find the 21 degree transom deadrise, with a sharp entry and an especially sharp forefoot to make the boat handle well in chop and following seas. We have hit rough weather many times and I find the boat to inspire confidence.
Guess it narrows it down, but that was a long period too.
Could it be British standard thread ? There is British pipe and standard ,they have 55 degree pitch compared to 60 degree pitch in American threads. And of course there are Metric threads also.
The machine shop commented on the thread pitch when they made the new nuts. Years later now, I can't remember what the final figure was. I'm sure it was just square end and metric.
Can't be pipe threads, as those are tapered, and wouldn't allow the nuts to seat the prop correctly onto the taper of the prop shaft.
I believe they are a special British thread. I did replace a shaft once and we had to cut the end off and send it off to ensure the correct threads were used. Mine has a castellated nut with a pin, not a lock nut. And clearly they are not a pipe type thread.
