Doesn't go fast enough even with two guys paddling?
I measure the speed of a kayak as speed relative to effort needed. The prism, my single yak, is fast. A few strokes and you go from stopped to moving and moving rather quickly. With the Zuma, the first several strokes go to overcoming inertia and then she starts to move. Once you have a little forward momentum, you can zip around.
As an example, I used to do a lot of canal touring. Wed take the yaks and a bunch of booze and some fishing gear and paddle through the neighborhoods of Kendall, checking out people's cool back yards, drinking, acting stupid and a little fishing for peacock bass. The fridge was always loaded with all the booze and the two worst paddlers but they kept up with the two singles.
