Pearson 33 with pressure dents from jack stands

1970 Pearson 33 Boat For Sale

I'm looking a this 1970 Pearson. Seems like its right up my alley. However, one of the jack stands has clearly pressed in the starboard bow. Its a big soft dent. No cracking of paint or gelcoat that seems to be related. Anyway, I was told that hulls will rebound from this kind of deformation once re-floated. Any truth to that? How serious is this kind of thing? I have no way of easily looking at the stringer locations and condition and such because of the fiberglass insert interior so I figured I'd ask here first.

Please give me reasons for your opinion, not just don't worry, or no way.
Thanks for your time.

i would take a very close look at it from the inside. hulls should not be flexible IMHO.

rdbeales · 14-04-2008, 14:37

Sounds like its only bad. What is IMHO?

gonesail · 14-04-2008, 14:56

IMHO means i am expressing my opinion on a debatable subject. a flexible hull is more than just bad. not being able to look at it because of a fiberglass interior is making it worse. but you don't have to take my word for it ... get a survey.

These things happen. I have seen many boats (including my own) where someone at a yard tightened a jackstand too much or used to few of them and "oil canned" in part of the hull. This used to happen once in a while at a yard I used with my old O'day 302. I would loosen the jackstand back and the dent would come right out on land - or other times would come right out when refloated, just like someone has told you.

But, if you're looking to buy it, you need to examine every clue.

Do as said above and inspect the hull in that area from the inside. Make sure there is no damage or anything funny going on with the stringers/various hull support points at that spot inside.

What he said. Jackstands should be located at a bulkhead so this doesn't happen, but it is not uncommon for a pad to push the hull in a little. The "dent" will usually come back out when the pressure is relieved, but even if it doesn't I wouldn't figure the boat was no good for one "dent" as long as there are no cracks. As long is the cosmetics don't bother you it could be used as an excuse to make an even lower offer.

I always was taught that there should not be much pressure on the jackstands EVER. The vessel weight should be 100% carried through the keel with the jack stands doing nothing but preventing the vessel from tipping over....Now if your vessel can not carry all of it's weight through keel??? Why are your boats carrying so much weight through the jackstands?? Yards that don't have a clue?? Surely not!!

That's exaclty right, Randy. Right on the money.

I try not to let any yard worker within 50 feet of my boat at any time! ha ha

You'd be amazed at the things they screw up.

One thing that really puzzled me about the boat I have now is that they had the refrigerator installed by a reputable outfit in Ft Lauderdale. This "outfit" hooked up the seawater pump to the wrong compressor fan control so that it would start and stop every minute or so. They also put the sea strainer in backwards. I have the reciept for the work, so I know they did it, not the PO.

I say... don't trust anyone to do work on your boat (except maybe a diesel mechanic).

The ground could be settling under the weight of the boat. That could redistribute weight to the stands

It is not uncommon to see some oil canning when the adjustment isnt just right between pads and keel support. Check it out but don't be overly concerned. It has happened with my boat a Cabot 36 made of Airex cored glass and one of the toughest fg hulls out there. If any thru hulls are in the area of distortion, give them an extra look and make sure they are secure.
