The Wavewalk 700 is a two-person boat and tandem fishing kayak that’s and assembled from two rotationally molded parts –
1. The Twinhull includes a left hull, a right hull, and a raised platform in between that joins these twin hulls together.
2. The Saddle is inserted into the cockpit, on top of the Twinhull’s raised platform, and it’s riveted to it. The Saddle is watertight and serves as flotation.
Some models in the W700 series feature a Spray Shield.
