You are not going to find a light kayak than a Sit In siade Kayak (SinK) like the vapor. My daughter has a vapor 10xt and its very stable with lots of room inside. I too use a Commander like Rick, but I have the 120 and I can pick it up and rest the inside of the cockpit on my shoulder and carry it. These kind of kayaks protect you from the wind better but do not take rough water very well.
Sit on Tops are best in rough water areas but have less storage unless its in bags strapped down. I have a Ride 135 in camo and its to be the kayak for taking the dog out as they water she brings in will drain back out. Many of these are perfect hunting boats like the Ride and the Predator, but they are not light as you asked about.
Also, kayak carts are worth their weight in gold. I put it mid kayak, ratchet it down, load up the kayak and start walking. The kayak does not have to be light, as long as you have a clear path to where you are going.
