@REI-LeslieN - I agree with @JasonB... I had gotten a tandem kayak and it was too heavy and big for me to handle by myself. Almost too much for me and another person to get up and off the car where it became a big hassle. I ended up selling it because of that reason and will probably get single kayaks in the future.
If you will be storing the kayak where you don't have to keep transporting it back and forth somewhere the tandem might not be a bad idea!
