om...
Just pull a small sea ray out and didnt belive the green grunge (for
the want of a better word) on the bottom and power washed much as i
could. Still a light green ammount left and looks like a weekend of
scrubbing. I tried checking archive for ideas but grunge didnt come
up. Please would anyone give some pointers on a solution to use to
help remove this; and to clear product i could apply to help stop this
next year. TIA, best regards...

Best thing to cut the algae on your hull is a solution of water and muriatic
acid (the same stuff used for swimming pools). Be sure and wear eye
protection, long sleeves (on a shirt that you never intend to wear again),
latex gloves, and a respirator, if you have one. It's a crappy job, but it
will cut the algae like nothing else. If you intend to slip your boat next
season, you can save yourself this grief for next year by getting your hull
painted with anti-fouling paint. It's the only real answer.
