1. Expedition Kayaking involves long distance crossings, the addition of a rudder allows for ease in holding a course over long and difficult passages.
2. Grand Expedition is built for smooth entry and exit through surf zones even without a rudder. The Rudder provides additional ease of control assisting in and out of surf for safe beach landings.
3. It elevates the control a beginner/intermediate paddler has in Expedition conditions.
This Model had extensive testing by Skils Canada and Rowan Gloag of "The Hurricane Riders"
Verdict: There is nothing that compares to the Grand Expedition for performance, comfort and ease of use for Expedition Paddling.
