Our boat has it and I was told that it was from being shrink wrapped
down to the waterline and the numb kid assigned to shrink it using too
much heat. It's on the quarters because that's how far he got before
someone ran up yelling, "You #$%^(*&^$ numbskull!" I could see traces
of the old shrink wrap edge and where it was cut back up to the rail
so I believe the story.

I was concerned about the ones on our boat; especially when I heard
the cost of repair. Someone told me to forget it, I would never see
them in the water, even at the dock. Sure enough, they are
practically invisible. I haven't noticed them once in two seasons and
forgot they were there until your post reminded me.

No blistering below the waterline or elsewhere on our boat either.
Sign of a good layup.

Forget about them and go sailing.

Hi,

I viewed a 1983 Vancouver 32 recently that had osmotic blistering
covering about 4 feet of the topsides below the teak cap rail on
both
port & starboard aft quarters. There are no blisters or signs of
osmosis below the waterline.

I'm concerned as to what might be causing these blisters, there are
no
visual clues. The deck joins the hull underneath the cap rail and
maybe moisture has entered here?

Has anyone seen anything similar before?

Thanks,
Peter
