- In one-rating systems, in light air races the J-27 flies and is hard to beat.
- In one-rating systems in heavy wind races, with enough wind to surf or plane downwind, the boat also does well and can sail to its rating.
- In that never never land of 8-18 knots, when the big boats are up to waterline speed, but the J can't quite surf, if your purpose is to win races you might as well stay home. (Edit - Blackadder - I don't really agree with this, the boat exceeds hull speed very easily offwind and surfs where others can't. It just goes faster and faster upwind and is really stable)
- In three-rating systems the boat does respectfully well, especially when the race includes reaching legs, so try and talk your area of PHRF into considering that system. ( Edit - Blackadder - 3 rating systems are the "fairest" PHRF systems as they cater for the differeng performance of boats on different courses)
- Some areas have seperate PHRF ratings for One Design vs PHRF where the ODR rating adheres to strict class rules such as sail inventory.
- Note that eg. on LIS the largest headsail used to be (still is?) a 153% whereas OD and many other regions use 155%
