I am pretty sure that the vessel discharge regulation started right here on the Chesapeake Bay. It began with pumpout stations few and far between, failure prone, expensive, lots of head refitting, and accompanied by a lot of whining. We now have pumpout stations widely available, our boats are delivered with compliant waste systems, pumpouts cheap to free of cost, better systems, and a cleaner bay.
California should subsidize the installation of pump out stations, and marina waste system installation, it protects a commonwealth. take it out of boating fees. Maryland did, and it worked.
If you can't be bothered to get your boat over to the dock for a pumpout, and don't want to pay for a mobile pumpout, you are not only a lazy skipper, you probably are not legally compliant on a number of your obligations, starting with your MSD.
This is the very reason that I quit boating into Cane Garden Bay, Tortola - the bay is a stinking cesspool.
