Yamaha and Kawasaki are the best engineered skis. If your going to be in rough water, you cant go past a Yamaha. If you are only riding in calm water a Kawasaki is fine too. The difference is the yamahas have a deeper V hull making for a better ride in rough water. You need to make your own choice about whether a 2 or 3 seater will suit you. Im not sure how much skis are in America but I'm a big fan of any XLT1200's or GPR1200's or 1300's. Ultras are great too but a bit smaller than a gpr but are great in the surf. You need to decide how you are going to use the ski before anyone can recommend
a ski. However, stick to Yamaha or kawasaki.
