A kayak is a small, narrow boat that is propelled with a double-bladed paddle. Kayaks are traditionally used for recreation and transportation by indigenous people of the Arctic regions. A sea kayak is a type of kayak that is designed for use in the open sea. Sea kayaks are often equipped with hatches and bulkheads that allow them to be loaded with gear for extended trips. They also have greater stability and maneuverability than traditional kayaks.
