36 Convertible Bottom Job

Well, RESPECT is the word that springs to mind!
Having seen what it takes to get jobs like this done properly, tackling it as a DIY project is indeed remarkable.
Very, very well done.

Ref. the blisters patches, let me guess: were they mostly along longitudinal lines, parallel to the spray rails and/or on the rails themselves?
That's what you typically find on many traditionally laminated hulls, and normally is rather superficial, affecting only the gelcoat.
If that is the case, after your treatment, I'm sure it will not be a concern anymore in the future.

Ref. the VC-17, did you already try it in the past? And in fresh or salt water?
In any case, I'd be interested to hear your view about its effectiveness and durability, because I read mixed reports about it.

PS: lovely boat, BTW!

Amen brother, nice job.
Also: appreciate the pictures.

Wow, 2 kts on a not so fast boat (low 30s, I suppose?) is a helluva improvement!
Do you possibly have any reliable indications from someone who tried the stuff also on salt water boats?
Here in the Med, that type of antifouling paint is almost unheard of.

Ref. the blisters, yep, that pattern definitely comes from the original hull moulding.
A bit tricky to explain, but it's mostly driven by the sequence and timing of the manual stratification by roller.
Rather common in traditional moulding, and has nothing to see with what is normally called osmosis.
I mean, it's still possible to find hulls with this kind of blister pattern AND also "deeper" osmosis with resin release, but they are different things, with different reasons.
The former being much less worrying than the latter of course, which in the worst case can even create structural delamination.

Thanks for the "Carolina smile" pointer, I never heard of that type of application.

Interesting to see M66 suggested along the areas more prone to fouling, because that's a rather popular product also in the Med, and widely considered very effective.
On the other hand, there are mixed views on any teflon-added paints like the VC, for three reasons:
Firstly, they rely on being slippery enough that any growth is quickly polished away with the boat movement. But if and when the boat is not moved for long enough to let barnacles stick on the surface, it's game over for self-polishing, and it's necessary to scrub or powerwash the hull again.
Secondly, as I understand, while it can also be applied by roller, it takes airless spray for the best results.
Last but not least, if you should decide to revert to another a/foul, it's necessary to remove it completely, which is a pretty tough job, with any epoxy.

Anyway, I guess it can be a good solution for boats which are either moving regularly, or are often pulled out of the water.
