I have either a CW Salmon River frame or a home-built version of one. I like how beefy it is, but am not stoked
about a couple things.
I run two larger dry boxes. The frame came with a front deck, but I got another box. I considered a drop bag, but didn't go that route. The bays are 13" wide, so don't accommodate rocket boxes. I have to put the groover in the gear pile if I'm carrying it. That's my main problem.
The only other problem is that it was built for someone much taller than I am. If I row from the cooler, the oars are way too close. If I row from the drybox, I have to sit pretty close to the front edge or just have the oars a little too far away.
One reason I think it was home-built is that it didn't have a foot bar. I called Cy and asked about it; he said they never build a frame without a foot bar. I had Timmy at Recretec install one (Thanks Timmy). That helps with the issue of the rower's bay being too long, but doesn't solve it completely. The other thing is I could still read the printing on the galvanized metal. The rubber was 16 years old when I bought it, but that frame sure wasn't. The seller told me it was an aluminum frame; I knew better and showed him with a magnet. He said that's what the guy he bought it from told him, but he was a contractor so should have known better.
I like/don't like the bars that come down inside the tubes. They definitely help make the boat more rigid. They also waste some space that I could otherwise use.
Timmy helped solve the issue with Captains' Boxes, too. We did two things. The second wasn't necessary because the first works so well. The second was a footman's loop attached on the back side to strap to the frame member that descends into the rowers' bay. The one that really eliminated my issue is he welded a small piece of square steel onto each box so they fit really nicely into the bay. They don't move now, and it's more easy to access the cooler. It's still not ideal, but it's totally doable. The harder part is getting padlocks off in the morning when I feel the need to lock out bears.
If I had to buy a new frame, I would definitely consider another galvanized welded frame like Cambridge. I would probably make the drybox bays bigger to accommodate rocket boxes, and I'd make the rower's bay shorter to accommodate my smaller stature.
