Layout of this really fun challenge took me a while. Also, please note that the solution suggested has port markers as green, and starboard markers as red. The *correct* solution is the other way round. The UK uses IALA A, whilst the US uses IALA B. It's a bit like driving on the different sides of the road.
very nice combination of tools, special and reporting tools, join, union, multi-row, cross tab... I liked it!
