One of the Open 70's had a dismasting, she's anchored right of Palapa marina with the top half of the mast hanging by the rigging - that'll be expensive to repair. I'm not sure about the round-the-island-race but that was the only one I'm aware of. There was only one other big incident, a medical emergency on the start where a crewmember lost a finger (which I gather was successfully re-attached in surgery). We had a lot of barging and some of it left scratches/dents and broken lifelines. But that's it - the winds were perfect and only picked up after the Regatta ended.
