Yes, I loved the way the swivel mount was used.
FWIW I thought there was reasonable concensus that a unit should be clearly visible from (& operable from) the
helm? But space constraints /
history / protection requirements probably spread
electronics around a bit.
People who bought multiple units or repeaters also had one at the nav station. PCs are safer down below.
My preferred solution is a bulkhead mount, only because I have a tiller not a
wheel / binacle. In close pilotage situations I seldom run on
autopilot, and I want the ability to relate the map directly to what I see (without popping up and down the hatch). I also want a plotter in reach of the helm to read details, manipulate the display, read off safe bearings, etc.
That said, my sounder display (which is set to display a bottom profile & huge numbers) is where it can be seen down the
hatch. (For protection.)
