This file was added to the post with the other polars. Looks very similar to the Expedition file.

J/30 Polars from UK Website in Excel Format

so ok ... i am missing something here?

1. do we assume that the polars going up to 22 kts wind are only using the 163? if not where do they change?

2. if at true wind speed of 6 ... true wind angle of 47.5 ... are we thinking that the tack is 95 degrees.

and then at 14 true, the tack is 86 degrees?

3. and then what is OPT VMG? to waypoint?

Also there seems to be a broken link re J/Boats

Vic - It appears that J/Boats has revised their website. I just sent a message to them asking if we can get the J/30 content restored.

A follow up to the post above about the J/30 content on the J/Boats site. J/Boats updated their site over the weekend to a new format. The portion for older boats did not yet get updated, but is in process and will be back online shortly. If any of the links have changed (e.g. the polars referenced by Vic above), we'll search the J/30 Class site and update accordingly.
