Having endured two Force 10 storms at sea, here's what I've learned: be as familiar with your boat as you can; know how to fix and have stuff to fix it with for every critical function on your boat; understand that no matter what you plan for - something else will happen.
Every boat is different and will react differently in a blow. When we were screaming downwind in the second storm, one of the seasoned, Great Lakes, sailors on the voyage posed the question: I wonder how my boat (he as a Tartan 37), would handle in these seas. The answer was, fine, we would just be doing something different.
