My wife and I have had a pair of Tsunami 140's for about 4 years. We chose these boats after paddling approximately 30 different kayaks from several different manufacturers and designs. The Tsunamis were a great fit for us. We use them for flatwater day trips, fishing, and even the occasional river with class 1+ rapids. We have even had them on Lake Erie in 4 foot waves. They have performed very well for us.
