SN was bought out (I don't remember who - maybe Alumacraft?) They continued making the 14R under a different name for a couple years, then discontinued it altogether.
The rib weakness is at the ends at the chine, where the casting transforms from round to flat. The flexing of the bottom causes a stress crack, then failure. Its an easy (but ugly) fix. Don't epoxy them - waste of time. The flexing will make the epoxy crack too.
Its a fine boat and served our family of 4 well for 23 years. I wanted a floor too - that's why I upgraded to a Starcraft with one already installed. Adding weight is never a good idea unless you plan on using the boat solo. Every pound added reduces the capacity.
In contast, my Starcraft is about the same length and beam, carries the same 25 HP, has a 0.100 hull (quite rigid) but the capacity is only 3 people and 400 pounds. The difference is the floor and the livewell.
