Rick, I don't want to be disloyal to you but 45mph (40- kts) seems impossible to hold with a cat.

As it happens, I was out at sea this afternoon windsurfing in 30-40 kts and I could only do that because of a sail of 4 square meter.
Which is about two/third of the sail with 20 kts.

Not to speak of the waves which I encountered far out, they were 5-6 meters and even breaking far out.

With a cat I have had several times gusts of 30 kts but I needed to open my traveller completly then. So 40 kts seems impossible to me.
Perhaps one short blow, but not the weather mentioned here in this thread by Tony.

To make my story of this afternoon complete; there were also kitesurfers with me on the beach and they finally switched to 5 meter kites at the end.
One guy returned from the sea stating that it was impossible for him to go further. He was very frustrated, shouting that he had once kited in 50 kts.

So, I know that in the sailing world there is a difference between the actual windforce and the one you are perceiving or hearing later by the radionews.
