what does my hull number reflect?

about time · 05-06-2010, 05:32 PM

I have a 1980 46' post sportfisherman. It has hull # 023 stamped in numerous places. Does anybody know what that means? I know post started in 1957, mine is a 1980, 23 yrs, hul #023???? Maybe 23rd 46' boat produced??? Maybe 23rd boat of that year??? How many boats did post build a year? Were they considered "custom", before becoming a "production' boat company in 1988? There is no HIN number stamped on the stern. I was told that this is typical for this time period???

Every boat built since 1972 should have a 12 digit HIN.

Is there a standard in the industry besides on the starboard side transom? I have seen other boats without a HIN # visable on the stern. Any suggestions on where else to look?

SeaEric · 05-06-2010, 07:40 PM

On my 1981 Post 42, I think the HIN was in the center of the transom just below the rub rail. As I recall, it was hard to read. It could also be on the lower stbd transom corner just above the boot stripe.

Has your hull been painted? Sometimes the HIN disappears during a paint job.

I will look closer at the transom area. Thank you for your reply. Any inclination on what the hull number might reflect? What was the hull # of your 1981 42'?

SeaEric · 05-07-2010, 06:42 AM

My 42 had HIN# PMC42194M81H. She was Post hull # 194 which you can see in the HIN. I had always assumed that she was hull 194 of the 42's.

About Time

Aside from the HIN. Post refers to its boats for their own use by size and hull count. for instance when I request info, I tell them my hull is 50-042. which to them means its 50 feet and was the 42nd hull of that length manufactured. I would guess your number with Post is 46-023.

I believe Post keeps info on every boat it manufactured by using this system

Possibly your hull maybe had blisters, was shaved and repaired and never got the nubers re-engraved into the new repair ?
I know of one other boat with that scenario.

Yes, you have the 23rd 46 they built. This timeline: http://www.postyachts.com/a_pgs/pgs_prd.htm may help you. Your boat is 2-3 years into the 46 run.

Almost every Post I have looked at in the water (being nosy) has the plate on the starboard transom just below the rub rail.

Your HIN should be like SeaEric referred to: PMC46023?80? Another 1980 46 HIN will probably have the same letters as yours to fill in the question marks.

Is your boat documented? HIN has to be on that blue certificate you receive each year.

Nope. I looked on the net. His CG Doc says Hull # is 46-023.

about time · 05-07-2010, 06:27 PM

yes my documentation says 46-023. Is that wrong? Do you suggest I get that fixed? I still can not find a HIN on the transom. I know the hull has been treated with Interlux interprotect but it has never been painted above the water line. Does anybody know approx. how many boats post built a year? Thank you all so much for the great info so far.

Mine hull # is at the water line beneath the boot stripe.
Mine is # 21 built in 1980.

Thank you Chesapeake46 I found mine on the starboard side right at the bottom of the bootstripe. Our hull numbers are #21 and #23 of 1980. I would assume we have the same power (6-71 J&T turbocharged?) I purchased my Post after she burned pretty bad. For 2 years now I have rebuilt her, almost done. I have yet to run her and was wondering what speeds and fuel burn to expect. I am told 20-21 knts on the pegs and maybe 17-18 cruise. Burning around 30gal/hr. @ cruise. My research has shown a wieght of apporx. 48,000 lbs, and drawing 3.5 '. How do these figures compare to your experience?

chesapeake46 · 05-10-2010, 07:37 AM

Congratulations on fooling yourself into believing you will EVER really be done !

I have 410 Hp, 671's with turbos.
They are rated at 2650 rpm no load and 2550 at full load.
I run mine at 2250.
Depending on the wind and the tides and the sun and the moon, I run at anywhere between 20 and 22 knots@2250.
At 2100 rpm I run around 19, 20 knots
I burn about 25 gals per hour consistantly.
My starboard tank always takes about 20 gallons more than my port tank which I attribute to the genny.

I generally do not let the tanks get less than 1/2 full and more than likely top off after any long distance travel because I like the boat heavey in case of rough seas. This is my own opinion.
I run the genny whenever I run the boat to keep it limber. ( 7.5 Kw Onan )

At 17 knots and below the boat does not respond well.
It is on plane but seems almost in transition, it wallows in a sea.

3.5 feet draft is the same as mine.

48000 Lbs is what I always quoted lift operators but I do not think it ever tipped the scales on those same lifts at that much.
I never wrote it down but I think the most she ever weighed on a lift was 42000 lbs. that was full of fuel but no water at all.

I only have 80 gallons water storage after removeing the original tanks that had split and replacing them with bladder type tanks.
This is adequate for my use around the bay.

Also mine is the galley down model which has a rinky dinky sized dinnette and long isle style galley.
The salon is pretty big and comfortable.
This boat layout is perfect for two of us.

I wish you the best with you Post.
I have enjoyed the heck outta mine.

Where will you keep the boat ?

chesapeake46 · 05-10-2010, 07:53 AM

About Time, a question for you....

why did the boat burn ?

I had an aquaintance that had a 46, (1979 I think ) that also burned.
It did not realy burn so much as get completely full of soot.
This was attributed to the trubo falling off of the exhaust manifold due to loose clamps.
The hot exhaust gas melted the cabling into a giant molten mass that would not budge.
The engine was trying to run at 2000 + rpm but with no turbo boost, it was a giant carbon pump.

The skipper could not move the emergency kill cables from on the bridge.
When he opened the hatch in the salon the back smoke ( soot ) poured in the boat.
Also the Port engine and genny were now breathing in sooty air.

He could not get to the fuel solenoids to manually shut the boat down and in the end he had ( I think it was his kid ) crawl up from the rear hatches to shut down the fuel valve to the motor.

A real mess and a real miricle thet saved the boat and people on board.

He did go on to rebuild the boat better than when he got it.
As I recall it was black and purple inside if anyone has seen it.
The skipper sold the boat I think a few years ago.
I cannot for the life of me remember the name of that boat but we ended up calling it " Velvet Elvis " because of the black and purple interior........

PS. I check those same clamps annually.
