I have had my Hurricane Aquasports Phoenix 140 for 10 years and could not be happier. Very stable SOT and had The Dinghy Shop in Amityville (sorry, I know thats nowhere near) put 2 rodholders behind me and as Scottie in front. Buy the accessories there and they install for free, or at least they did. I fish the Great South Bay (Lawnguyland) and usually catch more than on my 18' Sea Pro which hardly gets used anymore. There are several decisions to make on a yak, the primary thing for me was the lowest weight for a 14'. I put mine on top of the TracRac on my p/u and thus have to lift and slide the beast a bit. I am 5'8" 160 lbs and get my Medicare card next month so weight does matter. The Phoenix is not made of that crummy plastic like most of the yaks at Dicks but a shiny smooth plastic that is still quite tough. I doubt you will find one used, no one sells them once they get one. Another decision is color. I opted for the brightest that shows up on the bay, and that is yellow, with chartreuse or orange a close second. the bottom is white so the fish probably just see it as a cloud. sometimes I hop off to go clamming in the flats. try that with one of those eskimo sit-ins, lol. Some may say that the sit in is better for colder weather. I just took mine out today with the water temperature at 59. Its a yak, you will get wet, whether from paddle spray or launching. Out for more than a couple of hours ? Make sure the SOT has a scupper just in front of the seat, if you get my drift, no pun intended.
Good luck with the chemo, I got away easy last summer with prostate cancer, just getting radiated 45 times instead.
