ABSTRACT:
A land cycle for sailing on land comprising a recumbent tricycle with a first wheel and seat positioned aft of second and third wheels. A boom extending anteriorly of the front wheels engages a tricycle sprint to support a sailing system, which includes a vertically positioned mast engaged with the recumbent tricycle frame between the front wheels. A jib sail is positioned within a butterfly jib boom attached to the forestay and may be adjusted during use by the rider. The mast and combination of forestay, rear stay, mast sidestays and sprint sidestays cooperatively support attachment and use of said jib sail to said recumbent tricycle, thereby allowing a rider to apply wind force to stably motivate said land cycle. Further improvements disclosed and claimed include an independent rear brake, butterfly jib boom sleeve, a tubular jib spar, and a tubular forestay.
