Indeed ☺
There are many marinas with yards and separate tunnels etc. It works well when people work together, and can get uncomfortable when they don't.
Pump outs, you will probably find the moorers get discounted or free pump outs from a single point, although some marinas have a suction hole on every pontoon.!!!!
Tis a nice place however, probably not quite a large enough marina for the workshop to exist on its own, especially after Valley Cruisers moves elsewhere. Boot Wharf, Alvecote , barry Hawkins yard and charity dock are on the same stretch without even heading up the Ashby.
