The Spirit 55 is our choice for flat water touring & fitness kayaking that is stable enough to let us recommend it even for beginners. Made in one size this model is buoyant enough to fit paddlers of a wide range of weight. It has a smooth curved hull with a bottom that is flat enough to provide good stability without making the kayak too bulky.

For this the Spirit 55 is also available in "Para version", where the kayak is delivered with an additional paracanoe seat and a rudder locker as well - this locker lets you to fix steering cord so you can keep the line without the T-bar.
