Bestway Hydro-Force 2-Person Ventura Elite Kayak

Well, I was very excited when my kayak arrived yesterday right on schedule. Gave it a practice inflate at the house and then skipped work early to go hit up the local lake to test it out. The bag with the kayak and accessories is easy to carry down to the beach and inflates very quickly. Maybe 10 minutes after pulling everything out and inflating, I was ready to hit the water. I put my shoes behind the seat and my car keys in the seemingly sturdy zip pocket that's attached to the seat. The water was quite calm, maybe a little wind here and there, and the boat maneuvered wonderfully around the marina. I was having a ball. I saw birds perched on the rocks of an island and a big carp splash next to me -- or at least I thought it was a carp. When I returned to shore maybe 30 minutes later, I see that my shoes are missing from the back of the kayak. And it's hard to describe the feeling of dread I felt when I saw that, somehow, the zip bag on the back of the seat was open. And my keys gone. So there I was without keys or shoes, my phone and wallet locked in my truck. My apartment about 20 miles away. Luckily a good samaritan gave me a lift back home and it was maybe 2 hours before I managed to get inside my apartment. All of the 2 staff who work there had gone and there was no easy way to reach them. So what can I say? The kayak itself is everything I wanted. But something is clearly not right with the zipper bag on the seat. I assumed that it was designed to stay closed, but somehow it opened. Maybe it was the centrifugal force of the gently rocking of the water or me adjusting my position in the seat that opened it up. I certainly did not leave it open. I really wish it hadn't happened for a number of reasons. I went to the house of the maintenance guy, who I'm friendly with and who lives around the corner in a house, thinking he could easily help me. Turns out he was slurring drunk at 6pm surrounded by his wife and kids. He basically told me to F-off and nearly had a freak out that I showed up at his royal abode unannounced. The point of those details is to show that I'm probably going to have to take it easy and try to recalibrate my kayaking after this somewhat traumatic and stressful experience. It really was a crappy way to start out and my trust in the boat will take some time to rebuild. If the zipper opens itself under slight forces of the water and gravity, do I really want to trust my life in it?
