in my stumblings around I have seen a few potential boats that do not have outside or flybridge helm positions, makes for lower air draught potential for Euro canals which might be an attractiv idea.
When we had our live aboard 47ft trawler here in the USA, I never helmed it from the lower inside position except once on the original survey sea trial. How feasible is docking from lower helm position where a quick side to side look is less easy. We still have some nifty warlike-talkie 2 way headsets but sadly SWMBO, if line handling outside, has no positional awareness to say for example 'you are 2ft off the finger ' or 'shove the back in a bit closer' If she were doing the driving same applies, I could say move to starboard 2ft and she has no idea how far/not that is, cue a hard landing!.
So is this an imagined or real problem please? I'm talking about boats where you cannot stick your head out of a roof hatch or cover, but has solid side windows, with or without opening bits.
