osmosis again

[sjw]

Interested in a 1994 28ft Maxum the broker supplied me with a survey done on the boat at the end of August , great condition except for about 20 blisters per sq mtr which hace been previously been repaired with filler, he says that the filler needs to be removed ,re filled with an epoxy filler and re antifouled , obviously enough to put the survey client off the boat.The boat is now back in the water,so getting an estimate for repairs will cost me.any suggestions how much remedial work will cost so i can possibly have the purchase price adjusted to suit.

Worth speaking to Osmotech at Hamble Point Marina. They'll give you some idea of the cost and maybe inspect the boat if it's close

I had a Freeman 32 done by one of the International Paints franchises, under supervision of my surveyor.
Gel coat from waterline down removed using a "peeler", dried out in heated and dehumidified shed from Oct to April, Int' Gelshield applied.
Superb job.
Cost in early 1990's £3500.

Strangely, not sure cost has changed significantly.

At the sort of "blister coverage" you allude to, I would suggest you need to remove the whole underwater gel coat as we did.

Do you really really want this boat? It is the hardest thing ever to walk away but there must be a few other 28 ft Maxums somewhere in the UK.Even if you deduct cost of sorting the prob,suspect due to work load no one will be able to sort problem until 6 months time and boat will be unavailable for summer months while hull coating is ground off then drying out then recoat and then all the normal takes twice as long as should type delays.When you sell boat adding "recently treated for glass pox" will not add to the must buy list.

Dont mean to sound negative, however I agree with the "oldgit" it would have to be a fantastic price to justify the time and trouble to repair. I dont pretend to know much about the technical side of this matter but would the repair have any guarantee ?

The other way to look at it is you could pay full price for a boat that shows no signs of osmosis then a few years down the line it develops the problem and you're footing the bill yourself. At least this way I would assume that the seller is going to pay for it (by way of price reduction) and so you'll have a warranty for the work so hopefully 5 or 10 years of no worries (in that department at least!)

This was the approach I took when buying my (1981) sail boat

Not an expert,but this sounds a bodge job has been done once to sell the boat.Can you imagine the work involved filling that number of blisters.Maybe if a boat is gonna get the big O it will prob get it early in its life.?
If it has not shown up by 10 ish years reckon it is not going to show in the next 10.
As indicated on Dave Pascos www site a poorly done job will just result in a later reemergence .My reading of his articles indicates that like 10 year house damp warranties,the interesting bit comes when asking the repairer to redo his previous work.
Curious that USA boats appear to be prone to this problem.Poss something to do with heat or humidity during layup.

Yes - good points and certainly I'm no expert either. I agree the homemade fix doesn't sound great.

Odd about the US boats on that site that appear to be affected so much. Some real horror stories there!

Yes you have found your drean boat.....but..........
I also had a similar problem, although nowhere near as bad, and did a lot of research, I wont go into it here but I am afraid that I would agree with Oldgit … do you really want this boat.. it sounds like a bodge and will cost quite a lot to repair and then get an epoxy job done, which will probably not work, or at least not solve the real problem. Also as she is quite a young boat I would strongly suspect that she has more than just a surface problem...the bige 'O' is a real possibility, but after all is said by me or the pro's who look at the boat ... no one & I do mean 'No One' will give you a guarantee or tell you the truth.
A survey and a lift out is going to cost say £250 to £300 and the surveyor will ALWAYS err on the side of caution, & unless you can negotiate the price down to a sensible level I would walk away.
Now the good news....
It is a good time of year to buy as you have a 3 to 4 months of viewing boats at reasonable prices with a lot of them being on the hard.
Have a look at the recent PBO article regarding buying second-hand boats.
Also you must look at this:

Scary but very sobering stuff
