Professional osmosis treatment

[Bladerunner]

Can anybody on this site give me some idea of the cost of having a professional osmosis treatment done to a Westerly Pageant ?

The blisters have formed randomly from bow to stern and most are approximately 20 - 30 mm in diameter

Many thanks in advance.

A couple of years a go i looked at a boat that had osmosis and priced around to see how much the repair would be the prices quoted where around £3000 that was for a 26ft long keel yacht. Needless to say i walked away from that boat.

G'day Vince,

You will need to look a little further than the price, some do a much better job than others; most use power tools designed specifically to remove the gel-coat.

This results the loss of some fibreglass, but more important, it leaves raw ends of the fibres exposed. the 'better' operators will fill any lows and coat the area, than add a complete layer of rovings to provide protection for the areas left with raw ends just below the coating. they then apply at least 3 more coats of resin with a wash and sanding between coats.

The cost is not small, labour is more than 50% of the total, so you can save a lot if you DIY.

Having said that, no boat has sunk or fallen apart due to osmosis, so if you are planning to change boats in the next few years, leave till then, or take the drop in price for the treatment.

Meantime..............Avagoodweekend.

Those are large blisters and would not form overnight.

Blisters of this size infer a deep plane and so mandate some follow up GRP re-lamination. Adding a couple of layers of laminate bumps up the price of a pro GRP job.

All in all this might not be an economic proposition on a small elderly yacht.

Many thanks for the replies.

I have decided to have a surveyor look it over and see what he thinks.

Hopefully at the end of next week.

Hi.
I am coming to the end of 11 months without a boat due to having Osmosis treated, My boat is a 36' Westerly Corsair and she is coded for skippered charter and the surveyor insisted I had the osmosis treated before my next licence was issued. I am not sure why, but due to other thinks happening last summer I decided to have the job done, its been hell with out a boat, the only thing is I have spent a great deal of time polishing up the topsides and she will look great when she goes back in the water in the next couple of weeks, I think that by the time she is back in it will have cost me £5000 and on my boat value £60,000 this is worth while and means I can continue doing buisness fo the forseeable future, so the cost will be taken care of. But if I was not in buisness I dont think I would have had it done, yet at anyrate, One thing I should have considered was to take it to a yard that have Hot vac system, they promise to have the boat back in use with in 10 weeks its more expensive but in my case that would have more than been paid for, instead of 11 months, There are of course people that say its best dried out naturally and they may be right but my boat would have seen me out without treatment so if it only lasted 15 years I would have been happy after all it has taken it 15 years from new to get to the state it was, so if you decide to go ahead and get it done consider Hot Vac. they use it in Inverkip on the Clyde.
Good luck dont under estimate how much you will miss having your boat in the water,
Mike
