PROBLEM TO BE SOLVED: To enable easy and inexpensive aquatic exercise in warm water as outdoor and waterside enjoyment in all seasons. SOLUTION: The interior of a boat is changed into a water bath having a depth generally enough to reach the neck of a standing person, and is equipped with a combustor and a filter, so that external water taken in can be warmed up to a proper temperature. A wheel with pedals connected to a screw, oars or the like can be used to drift the boat on the water. A pinion connected to the pedal-mounted wheel allows the boat to move on a rack arranged in the water or on the land. |
