Sounds like good cruising advice to me. River City Marina (downtown Jacksonville) has gone through a succession of management over the years.

[Cruisers] heading northward up the east coast of Florida might want to avoid the River City Brewing Co. & Marina in Jacksonville. It looks good in the write up in Dozier, etc, but the bathroom and showers were filthy….chipped paint in the shower off the block walls that had to be a half inch high. Had not been cleaned in days….maybe longer. We greatly enjoyed the trip up the St. John's River….so much different from the hustle and bustle of the coastal areas. Small, county like marinas, friendly and well kept, lots of wildlife….especially alligators. Quiet and peaceful….but do obey the no wake rules in the manatee zones. We are back in Jacksonville now…at Ortega Yacht Club Marina…a very nice facility. Moving northward in the next couple of days. Have a Great Day!!!
