I get mud, sandbanks AND mountains & rocky islands in N Wales, no need for either or!
Christ ! I'll be keeping well clear of that then, sounds very dodgy with all that geography going on; round here the major hazard are SS boats ( think of them as an updated version of WWII German S' - Scnell - 'E' Boats out on marauding raids hell bent on causing as much damage and / or upset as possible ) fortunately one learns to spot them and do a reciprocal after a while.
