This could quite possibly be the fastest polyethylene sit-on-top that I've paddled! This boat has a low deckline making it less susceptible to crosswinds, but also compromising storage area under the huge trapezoid shaped hatches. There is also a small round hatch just in front of the cockpit that can be accessed from your seat. There is no molded in water bottle holder, nor is there anywhere convenient to place a drink. Lateral support is good even without a backrest (there is a removable, molded backrest that came with the boat).
Tracking is great even without a skeg system attached. The stern of this boat is flat, so a skeg or rudder system would be an easy installation. Primary and secondary stability are excellent with this boat. Mine is a '99 model, and does have a large "oil can" dent in the hull, but I notice no negative effects from this.
There are two drain holes in the cockpit. The ingenious part is that there are no plugs required; Hydra used a one-way scupper valve (a thin rubber valve) that only lets water out of the boat. Works great!
Overall, this boat is very fast and extremely stable, but has minimal covered storage due to the low deckline.
