While most of you are getting your 424’s ready for a summer of sailing,
I’m prepping mine for a season on the hard. Silverheels will hibernate
in dry-dock storage while I go play in the mountains for a few months.BTW, I just had her bottom stripped down to the gelcoat, which is
peppered with small, superficial, now-decapitated blisters. None of
those penetrated beyond the gelcoat into the fiberglass. There are only
6 small, “real” blisters in the entire hull, and none of those go deeper
than the GRP cloth skin; none got into the woven roving. Pretty cool
after 32 years.One surprise was the discovery that the rudder isn’t gelcoated at all.
Either a PO stripped it, or Pearson skipped it.Tor

Rich,
Maybe Pearson didn’t gelcoat the rudders, then. I wonder why. Anyway, it
doesn’t seem to have done any harm. I had no blisters in the rudder.Tor

I faired the trailing edge of my rudder by adding a bit of fairing compound. This makes the rudder about a half-inch longer but wasn’t done to increase control. Extending the length sounds like a lot of work. The rudder is pegged with blocks at about 45deg to each side. I wonder if you would get more control by extending the travel a couple if inches by moving the stops rather than extending the length.

Moving the stops would put the autopilot in danger and would just make flow
disattach sooner with no gain in control. I thought about that first as it’s
the easiest thing to do.Bob
I’m not being terse. This is from my mobile.

Interesting report about the blisters. When I bought my Pearson in 2009 the haul for survey revealed 25 years of accumulated bottom paint and thousands of blisters. I popped a number of the larger ones and none seemed to be deep at all. When I got it back to FL I had the bottom pealed and found none of them went past the gel coat. Basically the bottom looked really good as soon as we hit the first layer of glass.
Barrier coat starts going on in a couple of weeks.
I didn’t look closely at the rudder to see if it was gel coated or not. Will check that tonight.

I just had the bottom pealed on my 1980 ketch. There were a few small blisters and I also had several coats of old bottom paint slaking off. Once we got down to the glass, she was perfect. Epoxy fairing, 4 coats of barrier and some heavy duty paint and she’s beautiful. She sails better than ever.
Even better news, the tsunami hit while she was on the hard!
