Whats that green juice?
 

Many of the fiberglass/plastic boats I've seen here in the shipyard
have blisters that when you pop them like a zit are full of green
juice.

Just what is that green juice you plastic boat people deal with?

Joe

The call it fiberglass rust.
Bwahhahahhahahhahahhahaha.

Joe,
Not sure what it is but I've heard from reliable source that its
corrosion from steel hull boats mixed with salt water

GRP, boatyard, lay-up workers are all fans of chewing Skoal, Copenhagen, etc.
They can't carry their usual spit cup around with them when in the mold doing the
lay-up work. So, they spit the juices into the mold and lay-up as they work. These
juices are what one sees as a green substance coming out of some GRP hulls.

I hope this helps.

That is because you move in poverty stricken circles. The type of boatyard
that you visit is filled with incredibly cheap boats, that are owned by
life's failures. I'm quite confident that they wouldn't let you into my
marina.

Yeah right, your boat is so cheap the floorboards do not fit.
IE: The Bent a toe nickname given to your cheap production boat.

The boat I was poppin blisters full off green juice was a Tartan 37

Never seen or heard of green fluid running out of blisters. Maybe it's
from the chemical gunk in your harbor.

Actually Doug i think it's copper leeching in the osmosis blister from
the bottom paint...thats just a guess. Ive seen it on many fiberglass
boats

OK, that sort of makes sense if the boat has a really copper-heavy
bottom paint and rather porous gelcoat. I've never seen anything like
this but apparently you've seen a lot more blistered boats than I have
(easily possible, since I haven't gone looking for them).

Well this marina has a shipyard with the average of 20 boats on the
hard all the time. Every evening Skipper and I walk thru the marina and
see what new and happening.

If Skipper is a dog, keep a close eye on him around the boatyard. A lot
of stuff is very toxic, and dogs don't have good sense about what they
should or shouldn't eat or drink.

Getting back to blisters, I have seen blisters that were oozing water,
and some that were oozing a stinky yellowish gunk. Never green though. A
couple of years ago we saw a Hunter with blisters you could hide a
softball in. All over the hull, I couldn't believe that they didn't go
all the way through. Made me think twice about the oft repeated line
that blisters are never a threat to hull integrity, but then, that was
the worst I've ever seen.

Yeah Skipper is a Schipperky dog. I never let him run loose in the
Shipyard. However he still manages to grab gear adrift all the time.
Never let him drink from puddles ect.

Yeah Ive seen some pretty bad boats myself. The worst are usually
Hunters and Bent-a-toes and many different 70-'s era boats. Its a
fiberglass rust for sure. Good thing about steel it tends not to rust
underwater, the water line and 6" up area is where I focus most efforts
on hull preservation. Oh and carver powerboats are the worst Ive ever
seen.

Don't worry Joe, *he* won't rust.

Not a rust problem, Just all the bottom paint in the yard. They have
been tenting boats and putting tarps under them for a year or two now,
but still he shouldent be drinking the water, playing with rags,
chewing tape balls ect...........

I'm always very paranoid about our dog any time we're in a boatyard...
since my wife & I both like to walk around looking at boats, it's not
uncommon.

I've read that in the early 1970s they switched formulations in
polyester resin because of increasing prices, and the cheaper stuff was
a lot more prone to blisters. OTOH I've also seen some blisters on some
pretty high-dollar boats that supposedly were immune.


... Good thing about steel it tends not to rust

Really? I guess that's why sunken ships never rust?

My impression has been that the worst rust problems are always in the
bilge inside the hull.... possibly because that's where the poorest
access for rust removal/prevention is...


... Oh and carver powerboats are the worst Ive ever

Haven't seen enough Carvers to say that, but I haven't seen much about
them that's great either. Lots of crappily built powerboats out there,
worse than sailboats IMHO. If you ever want to check out a truly
magnificently built boat, look at a Fleming... the motor world's answer
to Oyster sailboats...

There is a 65 foot fleming in the yard right now. Its plush.

See if you can get an invitation to check out the engine room. It's more
than plush, it's a first-class job in every detail.

The boat looks it. Made me think it might be nice to live on a trawler.
If I bump into the owner Ill see if he will let me tour the vessel.
