I have a stock 12.5'x22.5" legend. It's not a light boat, I went with the double chamber design because I want to do high water silly multiday stuff.
Having come from rafts and IKs, I've used an NRS frame for the past 2 years because it is what I had. My frame uses the standard drop rails. I bolted some 2x3 L angle aluminum on as scout bars which works great.
Pros: I can quickly adjust the frame for light day trips, 2 cooler multiday trips, passenger, whatever. I can quicky adjust the geometry for a different sized rower. It breaks down easy. Zero maintenance.
Cons: Heavy. No way round it. The Drop rails fill with water (might be my bad due to the scout bars, but it adds significant weight at the takeout). Bulky bars don't take biners or make good hand holds.
I am picking up (at long last) a Madcatr frame next week. Why? Several reasons:
- I wanted a light minimal day frame for day trips on IV-V water
- I did not want to have cargo bays on my day frame
- I wanted the folding oar towers for trailering multiple boats
- I'm a sucker for functional art, and let's be real, this is as much an aesthetic piece as anything out there
For me, when dealing with the frame issues on the legend, I came to 2 conclusions. First, I didn't want one frame. Just can't do what I want with one frame. So, I went for a rowing module and a cargo module I can use, or not. I have a couple different sized ones depending on what I need to do.
Second: tube rocker and frame length. Because the rocker is present in the top of the tube, it is not possible to get the long frames traditional on cat boats. It's also a bear to trim the weight if you row from the front. I solved this with a packing bar in front of my foot bar that is independent of the tubes, so I can get weight forward when hauling gear.
I don't think I would have wound up with so well thought out a solution if I didn't spend 2 years tweaking an nrs frame and figuring out what I wanted. Protip: the NRS footbar mounted horizontally makes a dope packing bar.
Course, I already had an nrs frame lying around. Don't think I would have bought one new just to experiment for the ultimate frame down the road.
