Month trip. Bottom Paint?

[Cormorant]

We have a trailer-sailer with no bottom paint at all. We spent two months in the Bahamas and by the end of that time there was only a faint green haze beginning to be visible on the hull. I was actually excited to have "bottom growth," which meant we had finally spent long enough in the water to grow some. . . I'm sure it helped that we intentionally grounded her now and then.

Hey guys and gals.
We just returned from our trip and had a blast. We discovered that there was a little bit of splotches of anti foul paint left that seemed to do a little bit. I got out on the third week and gave the water line a scrub and the rudder but other than that I had very minimal growth. Almost the same kinda stuff I would expect if I had the boat at the lake for 3 weeks. I found that the sound stained the hull more than anything. I could tell which side had more coats of wax...
