Coleman Company was the owner of Hobie Cat back in the mid 1980's when the CompTip program was started. They maintained the program through two more owners of Hobie Cat (over 15 years). The current owners have no liability for the older boats. Coleman discontinued the program several years ago. In an effort to soften the blow when having to do a retrofit, you can order a CompTip from a dealer or direct from Hobie Cat for retro-fit use. Hobie Cat encourages dealers to pass the retro-fits through at their cost, but dealers are not obligated, in any way, to do so.
The cost of the tips are between 2 and 3 hundred dollars when used for retro-fit.
