I had two Hobie 18s from 1980 until 2000, the second one being a 1985 Magnum. It had a large open crack on each hull under the main beam and no reinforcing plates. After substantial repairs, we added the plates and had a dry boat again. Get them, they are worth the effort. I also repaired the centerboard case by mixing epoxy with microballons to a peanut butter consistency and then filling the bottom flange in all around on both hulls. That stiffened the whole case up substantially and stopped the leaking. It is fairly easy to do if you take the hulls apart and put them up on saw horses where it is easy to work on them with your (gloved) fingers for application tools.



Good luck,
