Jetstreak is a cool little boat. For me, tho, unpractical. I have a 12' 53 "Commander" (I guess) and a 15 foot I think 57 Voyager. The only thing I don't like about the Voyager is that it has two side seats which I guess were designed for storage. (Don't have the original seats). But they are quite low, there is no backrest, and too small for much real storage
The rear seat / spashwell "I thought" was going to be great---spashwell protects boat greatly from swamping, but makes engine access a (an actual) pain for me. Plus the coaming around the back is really too small for some of the larger engines--not enough room to properly tilt them.
I had a 58 "Flying Crest" 16 foot and the rear well was worse. The 75 that was on there could not tilt far enough to lock without crashing the engine into the bottom of the well.
Regardless these are cool old boats
