"Your Majesty, there is no second."
In the AC or Olympics, if you don't win, you're not a success. Period. Harsh? Sure, but it's reality. Top 10 is not winning, it's a list of the top nine teams that lost.
I have no problem with the splitting (unless it's complete desperation), but if not well planned, results in poorly executed (and extra) maneuvers, which is a horrific idea in fast boats that turn slowly.
Am I a world-class sailor? No. But I'm friends with more than a few, and have seen first-hand that extra tacks or gybes rarely work out on cats, and leebowing is a concept that is a complete joke on a catamaran. Anyone who tries it (leebowing) should be immediately removed from the course, along with the tactician and anyone else responsible for the decision, and never allowed back on a cat. Ever.
