Abstract
An amphibious sled has a body with a flexible frontal portion which is deformed inwardly and rearwardly to improve operational characteristics of the sled. In the water version, the flexible frontal portion is deformed downwardly, inwardly and rearwardly to act as catchers for waves and to aid in the propelling of the sled with water power. In land use, the frontal portion is deformed inwardly and upwardly.
