Great answer from the seller but also if you plan to go on a large lake consider few more things: this is not a sea kayak and it sticks out of the water much higher. Consequently, if the wind blows hard you can get quite a ride. Second, if you get in trouble make sure you have a marine radio to call for help... lakes such as Michigan or even worse in this matter Superior can get REALLY COLD even in the summer months once you wander away from the beach and drownings due to hypothermia are quite common. I have surfed Lake Michigan and Superior both when the waves were around 5-6ft in a storm (and if you can handle the boat) it is quite fun but if you are a new to the fun... make sure you learn the basics aswell as how to board the boat should you "go swimming" it is not as easy since the sides are about a foot up above the water- you will want to practice and be in good shape...big bellies dont help.
