After 
4 days of scrubbing, sanding and anti-fouling, we have now a very smooth, black silky bottom. It does look very nice and it was not as hard as we were expecting it to be. I had forgotten how satisfying working on the hull was… you can definitely see the results.
Let’s hope we go like the wind now without having to drag the barrier reef! Wonder if we will now average at 7 knots?
