Hi i am new to this.I am looking at an RL28 who's keel will not extend fully becaues of corrosion.i am on the Gold Coast, can someone give me an idea of whats involved in removing the keel and having this fixed and who would be the best person in my area to do the job. also any idea of cost? Thanks Paul.
It depends on how severe the corrosion is. I have had a similar problem. There are rust "nodules" that form on the board where the coating has been damaged and these break off and can jamb the board. I found the best way to get them out is with a metre rule slid down beside the board from on top and push them down while dropping the board, rather than bashing away at the board from the top with a hunk of timber as some people do. If the board is in reasonable condition you could just drop the board down and treat the visible part. If it is in really poor condition I guess it should be removed, but I haven't tried that.
The recommended way to treat the board is to sand off all the rust and coat it with rust converter. Then a good two-pot tar (such as Norglass Epoxy Tar) and then a two-pot epoxy undercoat (such as ShipShape Epoxy Primer). So, provided most of the board is in reasonable condition, none of this is difficult and with good preparation and this treatment it should be good for another 20 years.
Have just done some work on mine. Last year after cleaning I coverd it with 2 coats of a sealer given to me by the owner of a steel yacht who used it on most of his boat. It held up well but some areas wee gone. This time I removed some rust with a wire brush and after a wash applied 4 coats of Epoxy Primer and then 2 coats anti foul. Scraped a little off when raising and lowering the keel in the yard but it moved ok. Hope this helps a bit.
