I bought 8 feet of 2" SS heavy wall tube, (cost $60) and used that for our small JRC unit. It is bolted to the toe rail and braced to the top of the stern rail. So far (2 yrs) it is standing up well, does have a bit of flex in a seaway but nothing that has caused concern. The unit only weights 7 lbs or so, so there's as much weight in the tube as up top.
My only regret is it's 304 which in our area needs a lot of attention to keep looking nice.
I suspect aluminium may be stiffer. I also did not want the "vertical" strut look so cut and rewelded it at about a 5 degree aft rake.
