In your post it does not seem like you have spent much time on new the boat ? if that is not the case i have missed something
A week is sure more time to get to know the boat but not really a lot to take such a long trip in open ocean ,Please remenber i am talking about the boats weak points not yous
We will usally spend a week or more doing prep on a 200 mile LIS race on a boat we sail on every week
