Mounting Garmin 18" radome on 2002 310 question

[amajamar]

I am purchasing a 2002 310 which already has a Garmin 4208 chartplotter. I am going to add the Garmin radar to the system, but I am wondering if I need to put a wedge under it.

Also, due to a low bridge clearance at my marina, I want to keep it as low as possible (so probably want to mount it directly to the arch), and also make it removable for bridge clearance during astronomical high tides and for road transport.

Any info and ideas would be completely appreciated.

Thanks in advance!

I added a wedge when I put my radome onto my 2005 340DA. It is different for each boat. I called SeaRay and found out what wedge the factory used for their factory radome installation and went with that. Seaview had a radar mount that is hinged so you can lay it back down off the arch for clearance. Check it out online. I used Seaview on my install, top quality components.

Here is the hinged adapter that will fit Seaview mounts. This is a great way to go if you need it removable. http://boemarine.ecomm-search.com/r....com/seaview-pm-h7-hinged-adapter-map-272-00/

As an aside to my own thread... Jim, I just noticed that your profile indicates that you're from Kent Island MD. My boat, (which I can say as of last Thursday is now mine!) was purchased from Knot 10, so kinda' in your neighborhood!

Anyway, back to the topic... I have a low bridge clearance at my marina (11') and based on my calculations, the Garmin radar mounted direct to the arch would total about 10'-5 1/2", and would be fine most of the time. To use a bracket as you describe, I believe that I need to also use a strut long enough to be able to tilt down below the arch, effectively making it need to be tilted down on a regular basis.

My other idea was to use a flat plate of aluminum under the dome which would be larger than the dome, and use a threaded stud from the inside of the arch which would be held down by knobs at the top. That or use a very short strut (2") and use the same idea. That way I have clearance for all but the highest of astronomical tides, and the radar can be quickly taken down if need be.

Does that idea make any sense? Or are there issues that I'm not considering?

5.5" isnt much clearance,as a six inch wake from another boat could make you hit the bridge iron.I would consider the fold down and put a reminder on the helm near the key switches.

This should work.
