Yep, with the asymmetric rocker the boat wants to have the bow in front. A kneeling thwart is an easy and good option. If you paddle with the boat empty you may still find it bow light since kneeling thwarts are usually a bit further aft than optimum to help keep you from getting trapped between the kneeling thwart and yoke. I have a Polaris with an optional center seat (and no yoke) and I love the set-up and how it paddles solo since the center seat is in a better position than a kneeling thwart. The Polaris is similar to your NW16.
