Month trip. Bottom Paint?

I know of no other products that can't move between fresh and saltwater and still perform as intended.

I don't think the OP will ever need the paint again being a trailer sailor.

Don't many need to be applied and hit the water ASAP?

If nothing else a well struck waterline might look good when she is on the trailer.

If it were I, for a month I wouldn't worry about it. Most of the growth will be just at or below the waterline. A long handled brush will allow getting it from top sides.

Thanks for the advice Fstbttms. Being a fresh water sailer and using VC 17, I thought that all were like that. I think I would have to sand all the VC17 back to gel coat and start over to change. What is the best salt/fresh combo paint?

You beat me to it. The instructions for the paint I use say the maximum time out of the water is three days before the paint will be damaged.

There is no one "best". It depends on a lot of things. Many of the bottom paint manufacturers have paint selection guides on their websites. You put in various information on the part of the country, type of water, type of boat, etc. and the selector will pick the correct paint for you.

My Contessa 26 had VC17 on it and was in salt water. It didn't seem to be any worse than other bottom paints I had. Of course up here in the PNW the growth isn't like Florida etc.

In days of yore, prior to any type of treated pilings, I understand dock builders would use house paint loaded up with the hottest pepper they could get. Just food for thought about doing it with bottom paint.

The best? Pettit Trinidad, IMHO. But maybe you don't need the best.

I have never heard of (or seen) pilings coated with pepper-loaded house paint. But I can tell you with 100% certainty that it is a wives-tale when it comes to working in anti fouling paint. There is absolutely ZERO evidence that peppers of any kind are a deterrent to fouling organisms.

I'm pushing 73 and I probably heard that 40 years ago from someone my age then +, that had a marine railway. I did it, wouldn't even say it was scientific.
I bought 5 gal of surplus USN paint. Sat on the hill for close ten years launched and sat at my dock in a tidal creek for about ten yrs. Not a whisker of growth.
The paint, the environment or the pepper? You tell me. It was a suggestion since the OP being a trailer sailor if he uses bottom paint alone it will probably be a waste being exposed to air. My humble two bits.

I just did tell you. It doesn't work. If it did, you'd find pepper-laced anti fouling paints on every chandlery shelf. If it did, you'd find $20 an ounce bottles of ground cayenne at West Marine. If it did, every paint manufacturer in the world would be all over it.

But none of that has happened. Because it doesn't work.

As I said. Just my two bits with a very unscientific application. Some one can take it for what it may be worth or not. Was it the paint or the pepper? Most paints don't hold up when exposed to air for 10yrs or last that long with no whiskers In a tidal creek. Someone, in the past said the gov. didn't have access to any better paint than the public. That is probably pure BS so it may have been the paint. Either way go to a gov. auction and use pepper. Harbaneros (sp?) may be better. If I still had waterside and the paint, I'd paint one plank each way and hang them off the dock, just for shits and giggles.

Question, have you tried it?

The military is under no obligation to abide by the same laws and regulations regarding anti fouling paint that you and I are. That said, they have little interest in causing more environmental harm than they already do. So they use the same products that you and I can buy. In addition, many of their international ports of call have much stricter regulation on this issue than the U.S. does, yet the military still needs to visit these places.

So yes, the government can use whatever they like. But they choose to use anti fouling products that are identical to the paint you and I use.

No. Why would I? The true experts, the paint manufacturing industry, have told me it would be a waste of time and pepper. Why not mix vinegar into your paint? Just like peppers, it can be unpleasant to the human palate. But that doesn't mean it would repel fouling organisms.

As I said the pepper was not scientific or a controlled experiment just an observation. Do you really think a paint co. is going to tell you they make paint for the gov. using things band for public use by the EPA years ago? Gov. contracts are big business not nickel and dime gallons of paint. The fewer times they have to dry dock is fine with me. It is my nickel paying for it.

It has some type of bottom paint but it has all but chipped off. Previously the boat sat in an airplane hanger for about 20 years and I'm sure what paint was there cracked and the times I've taken it to our local lake chipped it all off.
My question is: should I just go as is and get scrubbing once a week while on water, sand off what is there, sand and apply a single coat of anti foul, or what? After the trip it'll be back on the trailer. We will have a fair amount of time on anchor so growth is expected.
This is (like everything for everyone) a budget trip. I don't mind doing work however. Any suggestions would be super helpful.

I'm not clear how the boat will be used after your North Carolina trip.

If you will require anti-fouling for freshwater use after the trip, I recommend Interlux VC17. It is a really fast paint. Almost all Lake Ontario (freshwater sailors) use it. Very easy to maintain. Won't build up or require stripping.

We have had trailerable boats that were slipped full season in Lake Ontario, that we took south for various trips (Chesapeake, Pamlico Sound, Pensacola, Keys, etc.) After 2 weeks, in the water the hull was clean as a whistle on haulout, every time.

I have a Lake Ontario customer with a 2007 Beneteau Oceanis 46, that took his boat south to the Bahamas twice, and never changed out his VC-17. Just had a diver scrape it with a plastic blade every three months. That he did it twice, is a pretty good indication that it wasn't a problem.
