I like AAA
AAA makes Clavey's frames so Clavey looks like AAA?
I imagine they are cheaper because there is no middle man. I am having them make me a frame shortly. the main reason I went with them, (although I am using DRE oar towers for width) is because their frames are much more adaptable. Since they use 4 detachable corners as opposed to two full width bent pieces (unless you're talking full diamond plate), you can add or subtract your lean bars, floors, without having to plan ahead and have all the fittings added before bending or incur a hefty "retrofit charge" if you already have your main frame, this won't apply. I am building my frame a bit at a time, so this was a big deal for me. also it is easier to change frame width if you use it on another boat in the future.
I am having them make me a rear anchor frame with internal rope routing like the DRE and Riverboat works. I also think their floors seem grippier, but haven't tried them on the water.
Also, they are super custom and will make anything you can dream up for a very competitive price. I am still in the process of figuring out the details, but they have been great. Plus, they always give me a beer when I come into kick tires. I am having them make the outside rails, and rear trailer frame, and the bent AL parts for the floor, but will use Rowframe.com fittings, and kickbar that I already have, and they are totally cool with that. i'm considering making the wood parts myself.
I do like their front lean bar better (less material to do the same thing, and very stable) but I am not springing for that quite yet.
In the end, you will be really splitting hairs, because all are great shops/frames, (Ron was very helpful when I spoke to him on the phone, but in the end wanted to use someone locally) Maybe there is a lot to say for a couple of unexpected beers?
