How is the black water being treated? Treatment systems are available but somewhat expensive and even their use is prohibited in some areas. For most of us, unless we are more than three miles offshore, we need to have the holding tank emptied on shore or by a pumpout boat.

As for long hot showers, that's what marinas are for. Shower water is commonly discharged into the waterway but you're not likely to have the fresh water capacity or the heating capacity for long hot showers.
