OK, pulled the boat this morning. Took a look underneath and found something strange. I have a 21 ft flat bottom skiff and just about the the whole bottom sits in the water at the dock. But only the back half has growth and two "stripes" of growth that look exactly like paint roller strokes

I'm wondering if different paint was used on the back and front of the bottom. Shouldn't I have growth eveywhere that is submerged in the water? Anyway I called my dealer to see what he has to say about it. Hoping he'll powerwash it off for $0.
