“Tail strikes???”
I know the tails are made of carbon fiber which I do not trust. It is in Formula 1 cars and it is incredibly strong but it can shatter like...porcelain? or Corelle dinner plates.
I think the tail fin failed in bad weather or something.
I just recycled a Canoe & Kayak magazine describing a new, 100%, carbon-fiber kayak (for whitewater rapids) that had to be redesigned with Kevlar reinforcement so as not to break up.
(Among some paddlers, Canoe & Kayak is known as Kayak & Kayak magazine). :)
