Reachers, Screachers and Code Zeros

These are different names for gennaker type sails that are generally found on more high performance cats. They are always flown off a centreline bowsprit. They have a relatively straight luff incorporating a luff rope which allows them to be used free flying but with a roller furler, ie, they are not attached to a stay but are hoisted and then unfurled for use.

The above image shows the straight luff and radial cut of a Cuben fibre reacher being flown from a bowsprit.
