Re the pens / points

It's in the SI's that you get a DQS and so drop a fleet. It's documented, if you don't like it, you have two options.

1, Don't sail the event. No one is forcing you onto the water
2, Don't hit people.

Looking at the damage, it was not a "glancing blow", that was a direct hit. It should be avoidable.

The damaged boat is no longer usable, I assume there are a couple of spares.

What redress did the boat that was hit get?

If I was wording the SI's I would have made it a non discardable!

This sort of damage can cause real problems in these sort of events, it's to be avoided at ALL costs.
