You don't need to make any changes to your forestay to run a non-furling jib. Add a jib haylard block right below the forestay attachment and a cleat at the bottom of the mast, opposite the mainsail cleat. That's really all there is to it. The Jib will attach to the bridle-ring at the tack, the halyard at the head, and the jib-blocks at the clew. You can use the standard Hobie jib with it's built-in forestay, a jib with a zippered luff that attaches around the current forestay (most small catamarans use this method) or a jib with hanks that will attach to the current forestay (better for recreational sailing than racing).
