Radar Mounts

[Jeanie P]

On CD22's, I see radar mounted flush to the roof just behind the running light. I see some on their own bracket and some mounted on arches. Is there any problems to flush mounting on a CD22?

Other than being able to slide a dinghy under it, what is the advantage to having a arch? Are they custom made for CD22 or can they be purchased from existing stock? Where is the best place to order?
Thanks.

It's nice to have a dedicated "tool rack" where you can install lots of stuff without drilling more holes in the roof. Even things like the VHS antenna and the gps puck can get in the way when mounted on the the roof handrails. Also a great place to put rod holders. I don't have one, but often wished I did. I think a seach of previos treads will show some recommended vendors.

Raising the height of the radar antenna by 2 feet or so will, (slightly) increase the effective range of the radar; either a mast or an arch can do this. The arch is not inherently necessary for storing a dinghy on the cabin roof, one could tie it down just as well without an arch. In my case the arch mounts the radar higher, provides a place to mount the GPS and radio antennae and is likely going to be the place I mount my MOB retrieval system. Fisherfolk like to put rodholders on the arch. Were I to do it over again, I would still go with the tall arch. Contact the factory and they should be able to help you with a supplier, warning, arches are not cheap.

I have not mounted one flush--just because I want it above the GPS antennas which are mounted flush or on short pedistals. The vertical meam of the radars are about 30 degrees, so you like to have it clear the top of the cabin--thus I like a short pedistal.

Personally I have not had the radar arch--The other antennas fit well on the roof, and less stress in one place. But that is not a huge issue. The arch puts more weight aloft, it makes the boat higher. I don't have the need for a set of rod holders up high--but some folks like those rocket launchers.

I had a 2KW dome on top of my 22, Captain's Choice. It was on a 10" pedestal and I thought it was a little high. I've got a 8" one with a 2 degree forward rake for Captain's Cat to mount the 4KW dome on. Hopefully, next week! There's a mount for a remote "GOLIGHT" searchlight on the front of it and a mount for either GPS or anchor light coming out of the back above the dome. The old one had the anchor light mount but not the searchlight one.

Hi Allan,

Flush mounting radar works fine on my 22’ C-Dory. Since I sometimes carry an inflatable on the roof, I mounted the dome so that its aft end is even with the Nav/anchor light. The dome extends on to the brow with custom made wooden blocks, so there is still room to carry an 8’ inflatable behind the dome with the Nav/anchor light in position.

There are photos of my boat that show the radar dome in
Cruises and Event photos Champlain Foliage , Erie Canal, and Rideau Canal cruises.

My flush mount works fine too although I will be putting an arch on soon.
I have a roll up dingy and like to store it on the roof. While an inflated dingy over the top of a flush mount works fine a rolled up one is apparently too dense and blocks my rear signal. My wife recently got G.A.S. and bought an inflatlable kayak so I need some more room up top.

I rubber mounted my flush mounted so the vibration when broadcasting isn't amplified by the roof. Nothing fancy just some good quality garden hose gaskets worked fine.

Thanks for the replies.
Charlie, let us know how you did after you finish your radar project.
Any problems or suggestion.

Charlie...what mount did you get? I'm going to be using the Seaview 10" aft leaning mount with a light bar and 2 degree base wedge. (Accoding to a chart I found the Furuno has a 20 degree vertical sweep, Raymarine has 25 degrees). I will mount the GPS puck at the top of this light bar.

Did the light bar ever cause any sort of blind spot on your C-22? I know something large like a mast can cause that but supposedly not a VHF antenna or small pole like a light bar.

Matt, it's a SEA SCAN mount aft leaning with a built in downward tilt (2deg I think), a light/gps mount (above the dome) on the back and a platform for a GOLIGHT remote spotlight on the front. Bought it on E-Bay. Never noticed any interference problem with the light support on the old boat.

Nice integrated rig! I was thinking of using Sea Scan as well. There are several brands out there and most look pretty good.

The first thing I did when I got my mount was to make sure the pre-drilled bolt holes matched up to the bottom of my radar. They matched up perfectly but I wanted to make sure before I started anything else! The mounts for Raymarine will not fit Furuno or Garmin for example according to the mount manufacturers.

[Captains Cat]

Thanks Dave. Thought about that and will either put black tape or "paint" of some sort on the back side of the bow rail where it has the potential to reflect back in my eyes. Thought the height would be an asset. Thanks for the comment! The TC bow rail is perpendicular to the front of the cabin top as it goes the width of the wide bow...

C-Dory factory has three different sizes of arches that give the following clearances. 17", 23", 29".
