The Parasail was developed as a variant of the Parasailor, and is a great light wind performer. With very little tendency to roll, it is ideal for small crews. It can be used with a spinnaker pole but it is not necessary. The Parasail has a single-skinned wing as opposed to the double-layer wing of the Parasailor.
