Re: Very Murky Upper Chesapeake Bay and Tributaries
My Micron Extra is still keeping them off of the hull. Just some slime.
As Dave says, my running gear was heavily fouled, and I lost over 1 knot of boat speed.
I used Petit Zinc spray on the running gear two YEARS ago, so I wasn't at all surprised to have to dive and scrape all the running gear.
