mounting Radar Arch 23' Sceptre

[samaha]

Here she is. 1978. Bought last August.
I can mount a radar arch horizontally on the gunwales, or on the vertical surface below the windshield.
Will those who have arches please tell me why you chose to orient your mounting brackets vertically or horizontally. Which way would you mount now?
How sturdy is it? Can you hang off it like an adult jungle gym? Rock solid?
