46 post verses 50 post

The 50' Post is wider then the 46. I think the bow is lower as well. I ran a 2001 50' Post SF with 900 mans. It cruised at 25 knots if I remember and topped out around 30 knots......

I have a '98 fifty . 820 mans. tops out at 36 knots at 2350 prm. 27 knot cruise at 1800 rpm. burns about 40 gals per hour at that speed - not bad for a 60,000 lb boat. The 50 carries more of it's 16' 10" beam aft to a hugh cockpit. good engine room access.

Don't know about the 47, but the 50 runs fine in following seas - ususually because I out run them.

Between 98 and 02 Post had problems with its gel coat cracking so check during a survey

Yes, the one I ran I think cruised at 27knots. I know it didn't top out at 36knots though.......lower 30's. It did suffer from the gelcoat cracking issue and Post had paid to Awlgrip the boat around 2005. It's been a year and a half since I ran it, so I don't remember all of the details as there's been a lot of yachts in between that I've ran. It rode pretty good.

The MANS are a noticable bit quieter, although vibrate more at trolling speed as they cut out a cylinder bank and stinkier a little bit. Considerably more fuel efficient, quieter and faster then the DD's. Your burning the same as the DD's an hour but going about 5 knots faster......then say a 46' with DD's. The ones I ran on the 50' ran clean clean at cruise. MAN parts cost a lot more then DD's as does the maintanence.

I have an '80 - 46 with 410 Hp Detroits.
19 to 20 knots at 2100 rmp and aout 25 GPH ( average )
The older Posts draw about 3' 6" and the newer one draw about 4'4".
I have never had a problem in following seas, in fact I think mine does very well in them . I pull the tabs up and raise the bow and it is fine.
That being said, I do not have a tender in the bow.

I think the 42's with a tender on the bow really had a problem with the following seas.

If I have a heavy following sea on the stern quarter, then I am very busy on the wheel.

One thing around the upper Chesapeake is the more narrow 46 is easy to get a slip for.
The smaller marinas can't always accomadate the wider beam.

I have 2 friends that went from 46's to 50's and they were real happy with them.
None of us fish the boats though.

What kind of boat do you presently run?

You are jumping up a lot of classes if you're serious about a 50 Post
The 50 is one of the premier battlewagons here in the NE. Will cost about $50K a year to run. Make sure you're knowlegable and ready for such a big jump just now

Good luck in your search

The 50' has engine room access from the cockpit. I am not sure about floor hatches on the 46' in the salon, but floor hatches in the salon will allow smells to get in easier. The 50' I ran had a 14' inflatable on the bow, as well as the davit, and 2 dock boxes for storage. It still rode ok with all of the weight up foward and I would transfer the fuel out of the foward tank as fast as possible which would help. It was only a little bit on the wet side with all of the weight up there. It did run faster and dry without the tender, but still with the weight of the davit and such. It was a nicely laid out 50', with a good cockpit, and was stable at trolling.

I'd say you're close. What about exterior maintanence- washing, polishing SS, waxing etc....... that's 5-10k per year.....
Figure bottom paint/yard at $5k per year because you'll have to do cutlass bearings, recondition props, rudder posts at one haulout or another etc etc......and $2k is light just for bottom paint by the time it's all said and done.....I would also budget $10-15k a year for longterm large expenses- gen, engine rebuilds, paint etc, enclosure/cushions.......

But if you're willing and knowledgable to do a lot of stuff yourself, you can cut it down quite a bit. And of course usage determines some of the maintanence. But, you're fairly close.

I didn't say it well, but going from a 30' foot outboard to any 50' twin diesel is a big jump in class/category of boats. So do your homework, like it seems you are doing.

$50K does it for me on all those items you listed and more.

The 80's 46 engine room access is through the saloon hatches.
I think if you smell the engine room smells like diesel then you prolly have a fuel leak somewhere or a spill.
My 46 does not smell of oil, diesel or head odors...

The biggest problem for me is having two bus engines beneath my white couch and white chairs...Plastic slip covers are good to have if you have Detroits. Thank goodness the rug isn't white too......

The 47's have deck access to the engine room but I do not know what year that started.

Hi,

You are a lot more likely to get CAT or Detroit service in those areas than MTU/MAN Service and the spares will be a lot more reasonably priced.
