A float device which provides an on-demand change in tacking or planing direction without having to retrieve the float or adjust the float configuration. The float utilizes a float body and at least two longitudinal keel members oppositely disposed on the float body. In a first orientation, the first keel is submerged and the second keel is in the air and the float tacks in the first keel direction. A sharp pull on a tether line connected to the float causes the float body to roll 180 degrees such that second keel is submerged and the first keel is in the air and the float tacks in the second keel direction.
