Road trailer deforming hull on Jeanneau Sun 2000

[BlackwaterBoy]

I have just looked at a 2006 Jeanneau Sun 2000 with a view to purchasing. The boat has been out of the water on its road trailer for 10 years.
I noticed that on both port and starboard sides that on one set of rollers the hull was slightly pushed in ie not holding its shape. As it was under the anti foul (old) I could not see any cracking or splits.
I have tried to attach a photo but not too easy to see. Is this normal for this type of boat or should I be concerned?
Thanks

I have no specific knowledge of the type, but that looks like a deformation WAY beyond anything normal. What is it like inside? I'd have expected the trailer to have been arranged so that the weight was taken by bulkheads or other structural members inside.

In olden days it was deemed correct for virtually all of the boat's weight on a trailer to be taken by the keel. The rollers (or bunks) were there to hold the thing upright.

I doubt much has changed

That's probably not the boat you ought to buy....

Sadly, that’s probably what leaving it for 10 years on anything does - unless carefully positioned on the bulkheads as AntPilot says.

Sorry, but unless the photo is an optical illusion it looks horribly deformed: far too much weight taken on lower hull sides. Ultimately it's only GRP and this is fully repairable, but not at all a trivial job to do properly.

Who knows what happened over 10 years .....

I've seen boat hulls deformed due to getting filled with rainwater and the props badly placed ....

I've seen people recover their speedboats and badly positioned - have deformation which 'popped out' when boat refloated and positioned better.

The boat OP shows ..... sad ... and needs to be lifted out and cradled properly to allow hull to 'relax' and be checked.

Problem with most trailers are they usually generalised and not for a specific boat unless bought specially. This then means that rollers / supports are at whatever position trailer production decides. For boat like the OP highlighted ... unless its purpose designed trailer for that boat - not a good idea to leave on a generalised trailer for 10 years !

Rollers on a yacht are a poor solution. I would want it on bunks and the main weight on the keel area.
On power boats the hull shape, especially with chines, will be much more capable of holding the hull up on rollers.

Looking at adverts for Sun 2000s a lot seem to be on roller trailers. Seems like a a bad choice to me.

I might not discount it completely - assuming that's an area of hull where there is nothing structural on the inside and there isn't any damage to whatever structural elements are closest to that area, is there a way that you can jack the boat up a little to take the weight off the rollers & see what happens? I don't imagine it would pop back straight away but might visibly start to relax? I've done this with a strategically placed bottle jack before, safe enough if careful and there are three points of contact so it's not going to fall over...

As said obviously bad trailer design. Weight should be mostly on the keel rollers. The dent will most probably just pop out. If you do buy it obviously you need to visit all the rollers and check the load on each. Many trailers have adjustable rollers so you set the pressure hopefully almost nil. ol'will
