First bottom job I have ever attempted. My Cal 25 II has been in fresh water for 3 years with noticable blisters.

Any help on the procedure repairing these once I''m out of the water or where to look for the information. (Having it done is pretty expensive !)

Depending on how extensive the blistering is the repair can be accomplished by exposing each blister with a small drill bit, drying and filling. Extensive blistering will only be properly repaired by plaining the entire area drying, filling and applying gelcoat.A cheep good reference is West System''s guide to glass maintenance.
Good luck

Last winter I handled the blisters on my ODay DaysailorII by sanding the bottom smooth (but not down to matt) with a Makita sander with coarse to medium sandpaper, then applying two coats of West Marine epoxy, then three coats of bottom paint. The boat spent the entire summer (5 months)in the water this year without any further blistering. An employee with fiberglassing experience at my local West Marine was very helpful. Wear a mask.

Instead of a drill bit, a burr type bit for the Dremel tools works very good. A miserable job! I''m glad I''m done. The most frustration is trying to dry out the blisters after they are ground out. Mine kept weeping orange goo for about a week. I used the West barrier system, but I believe that Interlux is better.

I have had very good luck removing bad laminate with a sharp wood working chissel. If you are only dealing with a few localized blisters this is a fast and easy way to go. Of course you have to grind out the divit before you actually start filling the spot.
