More ORC Certs

In the spreadsheet, above, I’ve added a different Olson 30, updated the J105, and added the Tripp 37 and the J44. It looks like both the J44 and the Tripp 37 will be hard to beat. The J105 looks like less of a threat with the updated certification. the other Olson is within a few seconds of us.

One thing that I cannot figure out is why the Performance Line Offshore numbers are so much more unfavorable (for the Olsons) than the windward/leeward numbers. Intuitively, since the Olson’s best point of sail is downwind, and since it reaches for sh!t, you’d think that the other boats would owe the Olson less time on the windward/leeward course. The opposite is true. The other boats owe the Olson less time in the Performance Line Offshore calculations. Is there an ORC expert out there who can explain this? Does Performance Line Offshore assume a straight line course with no tacking? Obviosly there is more to it than hull speed; because a 37 foot boat (the Tripp 37) is rated almost even, depending on the length of the race.

What’s the dealio?
