Kevin, looking at your hull, I'm guessing you may have a 2007 or 2008 Adventure. It sounds like Hobie has offered to send you a free replacement plus shipping charges. There have been a number of improvements in the hull since then including Click N Go Drive retention system (important improvement), new rudder design (AI version), reinforced scuppers and some minor changes (seat retention system, better side pocket bungees, improved PE, new side handles, hull flotation). It looks like your AI kit is relatively recent (second generation akas) -- you would have essentially a new rig that should be a lot easier to bolt up than our original Adventure (if you could get the AI version sent). This should extend the life span of your boat for more than the 5+ years difference in hulls and increase the value of your rig by at least your out of pocket expenses. Remember, the price on the new models is a few hundred more than your original boat so you're getting more features and a more reliable hull included in this price.
If feasible, and if Hobie would agree to send the AI replacement (I don't see why they wouldn't), this would warrant your serious consideration IMO.
