Norwegian Blue 11 Posted January 26 Share Posted January 26 Anyone have a set of polars for the 930? Quote Link to post Share on other sites
markm 31 Posted January 26 Share Posted January 26 Best place for polars is probably orc.org sailor services certificate search. Ultraman II and AYE SEA RED both have polars. 1 Quote Link to post Share on other sites

MartinRF 65 Posted January 27 Share Posted January 27 Here is a database of calculated polars. I don't know if there are any Ross 930s to be found there but maybe of interest anyway. https://jieter.github.io/orc-data/site/#NED/NED650 /Martin 1 Quote Link to post Share on other sites

Nope but at the moment I chose a Sunfast 3200 or Dehler 30OD as a benchmark. It would be nice to get something closer. Hmmm anyone splashed the cash on a Predictwind data hub yet and wants to loan it out? Quote Link to post Share on other sites

I can start with these and my MFD will tell me how I am performing against them. They look like class boats but at least that will give me a base to start from and then improve from there.
