Default Mounting Radar on T-top without Mounting Plate

My t-top doesn't have a mounting bracket. Other than bringing the boat to a welder to add a mounting plate, anyone have any ideas? I thought about mounting a piece of starboard between the two braces with u-bolts and then the radar to the starboard.

The pic is looking forward from helm.

You could have a mini-arch made that connects where the legs meet the t-top on each side. Figure @ $400 for that option. I've seen aluminum plates thru bolted right on to the cross-bars as well - starboard w/ u-bolts gets you the same thing w/out having to drill thru your tubing.

How heavy is your array, and do you think the two crossbars are strong enough to support it?

I'm looking at the same thing right now - my top has a plate, but it is not big enough to mount my radar. I'm thinking about building a support for it that goes across the top to each leg, for extra support, out of 3/4" starboard.

I did exactly what you described. I purchased the U bolts from McMaster Carr. I used a soldering iron to burn holes thru the Sunbrella for the U bolts.

I fabricated the entire mount out of Starboard. I have more pics in my photo album "radar mount"

BW23..... That looks great! My original plan was to mount a big piece of starboard all the way from bar to bar front to back, side to side, but your idea appears to be a better option. My only problem is that I would only be able to catch 3 u bolts at the T intersection. Do you think that would be enough support? I have an open array. I will weigh it when I get home from work.
Thanks

I think 3 U bolts would be fine ...especially if you use 1" Starboard like I did.

That looks great, BW!

moto - I've got a 48" open array, and it weighs 48 lbs (pretty sure). It's a lot more weight than a dome.

Personally, I am hesitant to mount it directly to my crossbars (which are 1" x 1.5" tubes). I like the idea of carrying the weight directly over the t-top legs. What I am thinking would look like the base part of BW's (the thick SB) cut in half w/ each side having the vertical support. I would mount those directly over the t-top legs to the aluminum plate (same as yours), w/ a 3/4" piece of SB spanning between them to mount the radar on.

Ideally, I would just get a mini-arch made for it, but I am about out of boat budget right now, and I already have the SB kicking around...
