I note your ostrich approach to the pin issue and no response re possibility of buying a new hull and rudder system only.
Understand... We read these forums... usually, but don't always get the chance. I don't get a chance to read every post. Especially on long threads, so don't expect that I know about everything you post. These are user based forums and not monitored by Hobie 100%, but we do try.
Fyi... We are making some in-house changes in the near future, Jacques Bernier (jbernier) - Technical Support and Brendan Castile (bcastile) - Warranty Manager will be taking the lead on support issues. They will be the primary persons monitoring and moderating the forums as I back away from warranty and support to concentrate on our parts and accessories sales division.
Since the pins are designed to fail to protect the hull... failures should be expected. As noted... I had not been hearing of grey pin failures. If there are unusual failures, report them to your dealer via warranty. We would like to see samples of any failed pins.
I must have missed the post where you asked if a hull can be purchased. As noted in other threads in these forums, replacement hulls are available to purchase if you desire that approach. You would have to work with your local dealer and they with your distributor (I assume is Australasia?).
