There have been a lot of different jib systems made for the Hobie 14, since the original boat didn't have one.
The Hobie Cat class-legal jib is made to be used as a furling jib and left on the boat as long as the mast is up. You can purchase a snorkle, raised with the main halyard, to cover the furled jib with the mast up.
Alternatively, you can rig a halyard system, similar to a Hobie 16, where the luff wire in the jib replaces the forestay when sailing. It's not class legal, but that's usually not a problem.
A third alternative is to have a zipper luff jib like the Hobie 18. That's more complicated, and won't work with the jib that you have.
