With that said, I would recommend the Klingon skirt- its going to be much drier on that boat rim. Keep in mind, that you will need to tighten the bolts on that boat regularly, to keep it dry. Many folks put aquaseal or gorilla tape over the bolts, to help with sealing water out. The Klingon is not your ordinary bungee sprayskirt. The skirt is designed to keep water out, by actually wrapping the neoprene partially around the bungee- so the neoprene creates the seal against the cockpit rim, not the bungee itself. We have also placed a sticky coating to the underside of the skirt, for anti-implosion purposes. If you have any other questions about the skirt, or what size would fit best on that boat, please don't hesitate to get in touch with us at firstname.lastname@example.org
Hope this helps answer your question!
