Golfman, I'm no expert when it comes to anything "boat", but I can attest to the maneuverability of the Assault compared to the Watermaster as I have owned and rowed both. I believe the rocker design of the Assault is the key. The Watermaster, lacking the rockered hull, may give a sense of a bit more stability on the water as there is simply more boat on the water, but I never felt like the Assault was unstable by any stretch of the imagination. Had I been a more experienced rower I probably would have gone through the area where we pulled out, and even as an inexperienced rower I was tempted, but the consequences of a missed line would have been ugly at best. With only a couple of floats under my belt I can say I'm very happy with my purchase of the Assault.
