J80 vs 7.9

Post by Pete »

Hello all. Any of folks raced against a J80 under PHRF. Is it no contest for the J80 or does the 7.9 have a chance at correcting to a decent result.

We've raced against a well sailed J 92 and we couldn't get close to them. We've also sailed against a pretty well sailed J 27, (during the same event/same course) and corrected on them in half the races. Breeze was light, (under 10 knots) for the whole regatta.

I'm going to state some obvious things, so please don't shoot me for it...

The J80 has to sail some pretty hot angles to get it's rating. On paper the speed of the 80 is significantly faster than the 7.9. This assumes the 80 is sailed in its OD configuration. Some 80s, have added genoa tracks, and equipment for a symmetrical spin to race PHRF. If this is the case, the actual competitiveness of the 80 is quite good (as good as the sailor on it of course)... physically the boat should be much faster than the 7.9 rigged with a genoa and a symmetrical (faster, but again if you outsail them you'll win from behind).

So in OD configuration, in a W/L race, the S2 should be able to kick the J80 keester (even well sailed). If it's a triangle course, the 80 will light up, just off wind, then it'll be a match of sailing abilities again.

The J27 is faster than the S2 as well, and it's a light air machine. If you corrected over them, you likely outsailed them, and considerably at that, as the J27's forte' is light air, moreso than the S2.

A J92 is also a hot angles boat, and in its ODR configuration is still significantly more sail area and waterline than any of the above. Its powered up pretty significantly from any of the above mentioned boats. When winds push you anywhere near hull speed, the 92 likely will eat your lunch, even in PHRF, and even in W/L courses. Because its in a significantly faster class of boat.. which would normally but it into a different fleet than the S2, or close to the next fleet. I'll note that some 92 owners have upgraded to genoa tracks as well. If you think the 92 is a neat boat, you ought to see the 92S (even more sail area).

Yes. On our CRW course we had several A sail boats. As the breeze was light the A sails sailed hot angles and most of the symmetrical chute boats were sailing hot reaching angles as well. It was as if they felt the needed to follow the boats in front, (which were the A sail boats). We found if the breeze was strong enough for us to sail the DDW course with the pole squared back,(up in lulls, down on puffs) board up and go for VMG to the leeward mark that was were we'd make our money.
