Who needs a motor? These kayaks can go through 8"s of water to those back bays full o' bass!!
You need a good paddle too..I like the MantaRay with aluminum shaft. 2 piece.

For solo, I remove the front seat & just slide the rear seat forward.
I don't claim to know everything..but I know what works for me. Spend the $$$ right the first-time & enjoy the best paddlesport.
