I've built 6 mini fishing boat frames (for trib 9.5, mini me, minimax) 4 of them for me. I learned a lot in the process. I'd skip the outcast boat and build a simple nrs frame (48" seat bar and fishing seat bar only, 8" towers and 7.5-8' oars) and stick it on the trib 9.5. The material is twice as thick as the outcast boat, no janky "frame" and you could build it for the same price and about the same weight. Put a basspto shops plastic quick release swivel on the fishing seat and you can remove the bulkiest item of you kit for travel or storage.
Plus theres a good chance you can find a lot of he stuff used. I never paid more than $1000 for any of the rubber listed above all used from either the buzz or craigslist.
If you have to breakdown for travel (i keep My little frame assembled and transport on the roof rack) Just loosen the 4 corner lopros and its disassembled. I used a Cordless impact driver to assemble frames on the river it makes it a breeze.
