Duke 1956

Our boat is moored in Cropredy Marina (so off the CRT managed waterway which is the South Oxford at that point) Since March 24th the marina has been closed and boaters are not allowed to visit the marina or their boat. Given that the boat is off the system for the time being (and probably for another three or four weeks at least) can I declare it off water and get a refund from CRT? Hopefully yes! Cheers
