I have a Predator XL Minn Kota. I use it for fishing/trolling. It's a sit on top kayak. Very comfortable seat. Has a 45 lb thrust Minn Kota motor that sits in the center console.
May be a little pricey at $2500 - $3000, but will do 5 1/2 mph and can go all day on a battery charge.
I have 2 canoes. One is 12' and I use it for solo and short trips. The second is a little over 15' and I have an electric trolling motor on it for longer trips. I've always preferred a canoe because you can move around a bit more. A kayak is usually faster but I'm not one to be in a hurry........Noah
A used Ocean Kayak (SOT) Sit on Top should go for $300-500 in good condition. They are stable and easy to get in and out of, practically indestructible and can be carried or dragged anywhere. The Scrambler is popular with divers
