Having cross-referenced Master Flood's track with my comprehensive collection of admiralty charts two things have become apparent to me:
1. Benjamin appears to be unable to gybe, and
2. The correct name for this location is "North-West Bank"
HOWEVER, I suspect if I were to ever spend time with the cartographer responsible for this name I would find his company tiresome, he clearly has no creativity let alone social charisma.
I have pondered the issue and and henceforth suggest the names "The Flood Bank", or to avoid unnecessarily inflating any egos, the traditional team for the last stretch of a river "Sea Reach"
