Im almost done doing the restoration work on my Windrose 18 sailboat

and am doing the fiddly bits now. Im needing to mount a fishfinder,
gps, cell phone etc etc and other small equipment and need some ideas.

I would like to mount everything on an articulated arm inside the
cabin that would swing out through the hatch and be visible/usable
from the cockpit, and when the day is done..be swung back into the
cabin and secured inside the cabin...out of sight and out of mind.

I dont care which side it would go on..it just needs to stick through
the hatch and simply show the face of the equipment to those in the
cockpit

Mount instruments in the cabin and run a waterproof phone outside with
USB camera attached?

You're going to want those instruments to pivot both down and way over
to the side so it leaves the entire hatch clear, I'll bet.

Just need a 3 part arm...so it will swing from the back wall of the
cabin (now beefed up with 3/4" marine plywood with a 1.5" gap behind
it and the actual cabin wall, mounted on SS standoffs) and then swing
around the edge of the hatch out into the open and out of the way..
Think of a "U" with the gear on one end and the mount on the other. Of
course..it could be an "S"
(Grin)


Any ideas how to construct an arm?

Articulately. groan (Sorry, hadda doit.)

Google "pivot arm", "ball mount", and "ram mount" for some excellent
ideas built by current companies. I've seen arms built with CRS bar
stock bolted together with large ball bearings welded to connection
hardware. Not pretty but usable. You'd probably be best off using a
rubber style ball mount like Ram makes since you'll be around water.
But they're damned pricy.

Ayup..they certainly are pricy. Hence my desire to build my own. If
the first one works well enough..Ill do it on all of my boats.

Ive got about 10' of 4x 3/4" aluminum slab I can whittle something out
of on the mill. Lots of chips and machine time...was hoping for some
ideas of something more time effective.

Thanks!
