Norbert Obenauf Great Auk

The Great Auk is a roomy, fast and stable kayak and tracks very straight. The long water line and clean entry permits it to cut through the water with a barely visible wake. The flared bow gives a very dry ride, lifting over most waves with little effort. This is one of my more stable single sea kayaks. It is one of the easier designs to build, with a fairly simple shape. This is a good all-around boat for someone wanting a stable, efficieint kayak. This boat is designed to accept a rudder but it is not required.

Beginner kayakers will find this design to be comfortable and reliable. While not a stiff tracker, it is well balanced and with a little practice novice kayakers will be able to take this boat a long way. It will not be a design you outgrow immediately. Larger paddlers will find this design roomy and capable. It can easily carry quite a substantial load so heavier paddlers will still find it usable for multi day trips.
