I was getting frustrated enough with advice from members and Hobie which didn't work...that I was just about getting ready to sell my Tandem for whatever I could get for it. But my dealer convinced me to wait and see what fixes Hobie might come up with.
Mate... take heart. The TI is a new product, with much greater stresses than the AI. Yes, it has some issues, especially in the rudder area. So too have some great big maxi yachts!
But rest assured, the Hobie people really do pay attention to these forums... Matt Miller I'm sure regularly passes on our observations and comments to Engineering, and even Doug Skidmore jumped in whilst Matt was in China... and he's the President of Hobie!
Personally, being of Swiss origin, I do like things to work like 'clockwork', but as a realist, I can understand that not everything goes as originally planned and tested (I'm a computer programmer).
However I have full confidence in Hobie's apparent philosophy of fixing stuff that doesn't work as well as they planned. So much so, that I recommended the TI to one of my best mates, pointed him to some of the issues... and Hobie's reaction... and he bought one too.
Fixes for something as critical as the rudder don't come quickly: engineers come up with designs, prototypes have to be built and tested, all before they can manufacture and release a permanent solution. But it will happen.
If the sailing kayak isn't your thing, sell your TI - you won't have any problem doing that! But otherwise, until Hobie releases the final fix, rest assured that if you post any issues you're having with the 'temporary' fix, or other problems, there are many dedicated members here (as well as Hobie staff) that are ready to help you!
