Should of gotten a Bayliner?

As a totally amateurish perspective on those flecks in the photo.... is it possible that some tiny particles became embedded into the surface while on a semi-trailer on the way to delivery? Could some tiny lava, sand, or even wood particles have become embedded into the gelcoat on the highway? And then slowly become visible as moisture made them swell...? That might explain why they are on the forward part of the hull, but not on the aft portion, which is more deeply submerged? John
 
Larry has it on a red hull.... so I it's not exclusive to green. Its below water line but only on the sides.... One theory has been that the dark green plus sun through water but then it should be allover.
 
Most of the blisters I have seen or dealt with were all different sizes. These seem to be pretty much uniform in size and shape. I am a little curious about these as well. Might be something else all together.
 
I know what it is: more of those biting bugs that you guys have swimming around up in Puget Sound. These must be the invisible fiberglass eating variety that live in the Great Lakes..

I recall asking about what type of resin was used when I bought my boat and was told the 22's at that time were made from standard polyester resin while the 25's were all vinylester resin. Could there have been a resin mismatch? Would it matter? Different shrinkage on the surface skin during curing?
 
WW|OW>>.. look at the fun I have been missing being off the net for a few days of UNPLUGGED good times.

I too have owned a Bayliner, an 1802 Trophy ENTRY level boat that all my non-Bayliner friends said I would regret...and loose my A$$ on... Well, as thows of you who know and have seen me... that did not happen...in fact... I seem to have found some that some others must have lost. Ya want it back anyone?? And that boat did depreciate, but ya know things just seem to happen for a reason...and when I had just returned from the Gulf Coast, brought her home, cleaned her up and waxed her down good (not near as nice of a wax job as Tony's job)...and a guy at the fuel pumps said he lost a great deal on one and was about to have the local dealer order him one.... Yep... I let go of the pump...and towed the boat to his house right then.... So...my Bayline expeirence was wonderful. No quality problems, many, many hours of great service and use...in a bunch of waters from the Chesapeake Bay (sp?) down to New Orleans, and many waters in between... Yall know I llike to travel...but...I took a ride on a C-Dory...and the throttle and me descided how fast or slow I wanted to go...not the deep v plaining hulll. I often found the speed I wanted was right in between the two...around 8 knots. some things do not change....hence...I love the C-Dory hull.

Engineers and Chemist issue... Humm... Kinda made me ask myself again why in the Army we have the Vetinarians over field sanitation issues, and mess hall inspections.??? Hummm.. Must have been all the time on the farms teaching them that mud and funk of animals is still way cleaner than most people...including the cooks....who....also are trained in sanitary matters... Humm.

Now... Jeff at C-Dory must be running for office... :smile I would vote for him... I can not wait until something is done...and something is said what the results are. Tony... I guess you picked up that C-Dory factory backs their boats, (toss the factory warrantee away...that is just stuff folks in the industry must have...PEOPLE MAKE THESE BOATS,,,, PEOPLE STAND BEHIND THESE BOATS THAT THEY BUILD.. I could not tell you even (or my best friend who just bought a brand new one...) how long the factory warantee really is.. I do not care. I have owned 3 C-Dory boats now. Are they perfect....No. The perfect boat has never been built. Do they stand behind their work...YES.

We brats take them in as if they are family....or at least the parts of our family that we like... :disgust


Relax, go use your boat, and all boats can sink on any given day.... Wow...they should make a movie called Titanic or something.

C-Dory will be there in some manner for you.

I'll bet you hear from them with-in a week.

It is Tues evening and I said the above on Sunday. It looks like you have been contacted by the Factoryguy as of Monday.

So I was off 6 days.

No one likes to have a problem with anything they spend a lot of money for. However, in my experience I would rather have a problem with a C-Dory than just about any other major purchase, ie. cars, trucks, homes. C-Dory WILL take care of it.
 
OK so here it is! The final word. The manufacturing engineer at c-dory says..."blisters below the waterline are caused by penetration of a small amount of water into the gelcoat through osmosis. I am told that it is completely cosmetic and is in no way structural. It is more prevalent in fresh water and around the waterline. It is also more prevalent in colored gelcoat. (green, red, etc) Colored gelcoat has volatile organic compounds that are used as part of the chemical make up that are more susceptible to the blistering."

Dan I did cut one open and there was no water that I could see, not saying that it did or did not contain water just that all I found was gelcoat. Their did not seem to be an air pocket that water could sit in.

As far as the warranty on a c-dory. You can read it if you like but I think you should just throw it away. Because you don't need it! It dose not seem to matter what it says. Jeff and the others at C-Dory will stand behind there boats no matter what the warranty says! I am proof of this. C-Dory has agreed to fix our boat and not only that but has a way to do it so that we would not be confined to bottom painting. :lol: That alone could save us 300-500 a year on bottom paint. We have agreed that if the blisters stay as they are we will do nothing. C-Dory has agreed to fix them if they become any larger. They even put it in writing! WOW

So If you are thinking of buying a Dory or worried about the one you have, Have no fear for Jeff is there watching out for all of us. I know that my Father and I have a renewed confidence in our boat and her manufacture. Speaking only for us this was a vary expensive 22 foot boat, and if we could rewind time we would still buy a C-Dory. We might of saved another year and gotten a 25' but it gives us something to look forward to in the future.

Thanks for all the help in bringing this issue to a resolution, could have been a lot harder with out the help of fellow C-Brats ( even you Hampshire). Dan thanks for your expertise you were right on! ( mabe I shouldn't tell him that it could go to his head! :shock: )
Regards Tony
 
"a way to do it so that we would not be confined to bottom painting."

i have a problem in our lake that requires painting or a lift.

from the statement tony recv. from factory would anyone advise how this works.

boats in our lake can blister within 2 -3 years.

thanks for the help

Jim No I don't think I explained this well enough. The factory has a way to fix the gelcoat pimples on the colored sides with out Placing resin and bottom paint over it. The only other option for me was the resin and bottom paint wich would cause me to bottom paint the boat yearly. We do not need to bottom paint here. Sorry no cure, wish I could help though. I bet that Dan could explain it a lot better. Tony
 
Greetings:

I have been following this thread closely and am certainly glad that things worked out.

I have mentioned Aurora Marine's VS721 sealer/wax/protectorant in the bottom paint thread. Reading about the product http://www.auroramarine.com/, the company claims that VS721 will seal the bottom of your boat and protect it against osmosis. Now more than ever I am interested in this product. Just might order some and give it a try.

In the question and answer section of their site, they give a description with diagram on how to lift your boat off the trailer with blocks and a jack.

Would like any input on any of you who are familiar with this product.

I am certainly glad this all worked out. I figured C Dory would respond favorably given I have never heard of any bad press on the factory. 8)
I know one thing... I am using this thread to TRY to convince my wife a C Dory is for us... more specifically a 25'. She says the cock pit is too small... but I beleive it is just fine.

She has gone so far as to agree to a test ride on one at Cutter Marine in Baltimore. Guys.... keep all your crossable appendages crossed for good luck for me! I will keep you posted!

In the meantime, I want to look into the mechanics of osmosis on fiberglass boats. I always thought (wrongly) gelcoat was impenetrable. If anyone has any sites that they could suggest to get me jump started I'd appreciate it. Thanks all and again... Good going Tony! Butch
 
Thanks Dave! Great articles.
I got one major question answered regarding the application of osmosis to gelcoat and glass webbing. For osmosis to occur liquid must be on both sides of the semipermeable membrane (here gelcoat). I had no idea that gelcoat, resin, and glass ws that porus. That blew my mind... wow!

The other source of blistering is caused by a chemical reaction called hydroloysis, where water, a universal solvent, chemically reacts with a substrate (gelcoat).

This topic has really spiked my interest... as I have never owned a fiberglass boat...

Later, Butch.

The article gave quite a bit of good, practical advice, but minimized the effects of osmosis. My understanding of these blisters is that water slowly diffuses into the laminate (or, if you like, through the gel coat), and if the cured resin is susceptible to this, breaks down (hydrolyzes) the ester bonds that join the resin monomeric units into a polymer. This transforms it from a stable, solid material (the polymer) to smaller molecules, which are water soluble, forming small inclusions of water solutions.

Because the concentration of water "outside" these enclosures is greater than "inside" them, further diffusion of water from outside the hull is enhanced (this is what is meant by "osmosis"). This leads to more hydrolysis, and more water in the enclosure, and it expands, forming a blister. At some point, the greater pressure inside the blister defeats further migration of water into the blister, and the process slows down to nearly a standstill.

Without osmosis, there would be no blisters. With hydrolysis, there will be osmosis. So, whether you shoose to concentrate on the osmosis or the hydrolysis is moot: If any hydrolysis occurs: you got blisters, which will grow with time.

The root cause is the makeup of the resin, so that if some hulls blister, and others do not, the place to look for a cause is the resin.
