Recently, I was 5 miles off shore with my wife fishing when suddenly the fwd left AkA detached from the the fwd crossbar. Fortunately, the winds and seas were calm and I was able to reinsert the AKA back into the cross bar. We aborted the trip and when I got home I played with the AKAs and determined that it only took a short, sharp tug on the fwd, left AKA to have it pop out. By coincidence, a few days later I received a new fwd crossbar from Hobie, due to a weld crack on the mast receiver. By looking at the old and new cross bar and playing with different possibilities, I determined the failure was due to the AKA retaining clip on the fwd crossbar. I believe these clips wear out and need replacing. I my case, my old clips had lost about half there outward spring ability and was not fully engaging the AKA knuckle. Below is a picture of the clip:
I have emailed Brandon at Hobie to identify a part number and order new ones, but he has not yet got back to me. I recommend everyone check this item for potential failures.
