1.5" tubular stainless rudderstock doesn't exactly sound "massive", to me... However, perhaps the most surprising aspect of this particular boat, to me, is the fact that she carried a pair of 3-BLADE FIXED PROPS... On a half million dollar performance cruising multihull??? WTF?
They had just bought the boat planning to retire on it.
Rudders are by far the most fragile part of sailboats and most accidents and boats abandoned had to do with some sort of rudder malfunction.
This was an weird accident in a sense that it is not a vulgar one, I mean ruder being broke with the boat violently thrown backwards by a wave. That can put a huge stress on a rudder that is not designed to take it but the truth is that not many dissemble regularly their rudders for inspection and changing worn parts. I would say that a rudder should be inspected (dismounted) at least all 5 years, even id it does not seem to have any problem and more frequently if an ocean crossing or extensive offshore sailing is to be made.
That is not very expensive on a spade rudder type and certainly it is money well spent.
