[C320-list] Rocna 15 Anchor Fit on Early C320s - Hull 268

[Jeff Hare]

Hi,

A trick I've used very successfully that would probably work here is to get a spool of quality synthetic waxed whipping twine (not cotton).

Once the bolts are removed you can start at a corner and cut away a little of the adhesive from the forward edge with a x-acto knife to make a slot to get started.  Use the twine to saw back/forth and cut your way in through the adhesive.  

As you get the twine in a little distance, tap in some little wedges or even a butter knife behind it and keep going.   You'll go through quite a bit of the twine but it works.  It's how I release my entire mast step base that was glued to the hull.  Worked slick but did take a little time. No gelcoat damage.

After that, I used 3M adhesive remover to clean up the gelcoat and parts.

Good luck.

There were bolt holes in the new roller, but I don’t know if they lined up with the previous holes. Since the old holes are covered by the new roller, I would have just filled the old holes with caulk and drilled new holes to match the new bolt hole patterns. I either used the old backing plates or made new ones. Again, very easy to access and fit either way.

I just dug out as much material as I could and then wedged a pry bar between the bottom of the roller and top of the deck. Each time the roller lifted a bit I would cut more caulk with a thin chisel. With patience, the gel coat survived. Good luck.
