Five years ago, in Portugal
, we had coppercoat applied to our bottoms.
For the first year it looked like it was doing a reasonable job. But after that first year it became increasingly unimpressive. Indeed for the last three years we would have to scrape the bottom every few weeks to remove the growth, which was mostly a very tenacious green weed that would grow to several inches long. To get it properly off took vigorous scrubbing with a scotchbrite. Not easy underwater.
A year ago we had it on the hard
and did another thorough rub down to 'reactivate it' as our last ditch effort to make it work
. It looks the right color. It is nice and smooth. But it does not impede growth.
LIfe Part 2 was in Simpson Lagoon
, St Martin
for 2 months. When we got back the growth slowed us down by a full 2 knots.
This time we left her on a mooring
for 6 months (since March) and came back to a full ecosystem:
We have green weeds, colorful sponges, tube worms, shrimps (including a banded coral
shrimp - never seen one before), crabs, a tiny 2-inch lobster, the tiny shrimp/krill/whatever that get in your hair, ears and everywhere esle, lots of different small fish
, including some that are living in the water
intakes for my toilets - they then get sucked up and smashed up in the intake strainer, thus blocking it. A few barnacles
too, but not a huge number.
Fortunately it all scrapes off pretty easily, like a 1970's shag carpet. and then swe rubbed it all down with scotchbrites.
So on our next haulout we are going back to bottom paint
. Maybe Island 44 hard?
Yes, these pictures are our boat
bottom. The last one is the before and after scraping.
