I actually own more kayaks than guitars TF.
The SOT I took on the float was a Wilderness Systems Tarpon 12, a gift from my co-workers when I retired 6 years ago. I built my first kayak (skin-on-wood frame) back in 1969 and at last count have owned 28 different kayaks over the years. Like you, as I got older and my bad knees made it harder to get in and out of my SIKs, I switched to SOTs about 10 years ago. I still have two SIKs hanging from my garage ceiling (Perception Acadias) that my wife and I used to paddle. My first SOT was a 12' Native Watercraft that had good storage capacity and a good paddler, but I wanted a shorter boat for some of the tight,rocky streams I fish so I bought a Wilderness Systems Tarpon 10. I liked the boat but it had those annoying "ankle biter" foot braces. A couple years later my local boat shop (owned by one of my paddling buddies) offered me a deal on the newer Tarpon 10 with adjustable braces so I bought one. When I received the Tarpon 12 as a retirement gift I now had two 12' and two 10' SOTs so I gave a couple to my son and his wife. With the birth of a son a couple years ago they never get the chance to get out and paddle and really don't have storage space so recently he asked if I minded taking them back.
Sooo...... I now have 2 rec SIK, 1 WW SIK and 4 SOTs hanging from the garage ceiling, along with a 16' river canoe, 17' lake canoe and two rafts.
Choosing a yak is like choosing a vehicle - everyone has different opinions. However, from my experience SOTs are a lot more comfortable to paddle and fish from (easy to enter/exit, sit side-ways and hang your feet over the side, access your cooler and gear easier, etc) but they are much heavier and if you run the steep, shallow, rocky streams I tend to float, rocks will eventually damage the area around the scupper holes, especially in the area under the seat where most of the weight is concentrated.
At least once a year I put new kevlar patches on the hull cracks but since kayak hulls flex more than canoes, the patches eventually fail or crack from hard impacts with rocks. On my recent float I took shoe goop, contact cement and some flexible hypalon (raft material) patches for emergency repairs. Besides the kayak damage and guitar bridge failing I also needed to repair a cracked paddle blade and my Keen wading sandals. The goop and glue did a pretty good job.
PS - The guitar was on old beater "river guitar", but I should have it playable again by the end of the week.
