Re: Repainting the Hull
Sorry, have never tried paint stripper.
Any product would have to be checked to ensure it did not also remove the fibreglass and resin that is what makes the boat watertight.
Careful use of an orbital sander or very careful use of a disk sander is generally the go. Remember that you are working with only 4mm of ply so you do not want to dig into it.
We have also used a heat gun to strip back an old boat. Again great care must be taken not to disturb the glues, resins etc that hold the boat together and stop the water getting in. I think my husband used the heat gun over the middle of the large panels then sanded the tapes areas, plus of course a final sand over the lot.

Re: Repainting the Hull
Hi there.

My name is Ryan and I have just helped my dad strip down an old Sabre. We found that the most effective thing was a belt sander with 40 grit sandpaper worked best. Also if the boat is a wooden one a heat gun and paint scraper also help alot to get rid most of the paint. - Don't go heavy handed with the heat gun near the fiberglass joints as they come undone! - Depending on how much paint is on the boat you could be looking at roughly 50 working hours to do it right.

Well hope this helps...

Ryan

Hello just wanted to give you a quick heads up and let you know a few of the pictures aren't loading properly. I'm not sure why but I think its a linking issue. I've tried it in two different internet browsers and both show the same outcome.

Re: Repainting the Hull
I warn against quick removal tools like a belt sander. A 125 is a 3 ply boat and the outer veneer is very important for structural strength. Sand it to a 2 ply boat and you will have to fibreglass sheeve the outer hull. I only remove as much paint as is necessary to reach a good base. This is quickly and easily done with a random action orbital sander with 100 grit for quick removal and 200+grit prior to final top coat. Sanding scratches from the 100 grit are easily filled with a free sanding marine undercoat/primer, which is then hand or machine sanded to a very smooth finish with 200+ grit. Remember that paint dries with a surface tension action drawing the film to a gloss finish following the contours of the surface underneath. A sandpaper sctatch will be magnified with a gloss finish. Painting is best with a spray gun, but most 125 owners do not have this equipment so hand brush on a cool day out of direct sunlight and remember to draw the paint film out finishing with long light strokes in the longitudinal direction. Work from one end and don't play with the paint once it is starting to dry. Try to keep your "wet edge" fresh.

Re: Repainting the Hull
There are no real shortcuts when repainting a ply built hull. If you use an orbital sander you will have to spend much time re- fairing the hull. Definatley not a good idea. Same goes with paint removers, very dangerous in terms of damaging your boat. You can use an electric sander just to remove the gloss off this top which will reduce clogging of the sand paper when you finish it off by hand. Just remember that its a very hard job to get all the imperfections out of the hull if its first re-paint. Each time you re paint it will get better and better. Have fun!
