markm 30 Posted July 3, 2019 Share Posted July 3, 2019 Only data I have is from a couple of Canadian 930s in ORC scoring tables, not perfect for loading into instruments but should be a reasonable starting point for you. Can't upload an xls so try link http://www.racetrack.org.nz/XLS/ross930.xlsx Quote Link to post Share on other sites
splat 55 Posted July 3, 2019 Share Posted July 3, 2019 Why do those look slow to me? Quote Link to post Share on other sites
markm 30 Posted July 3, 2019 Share Posted July 3, 2019 Think the upwind and downwind boat speed is VMG Splat, they look pretty close for that. Think I have the maths lying around somewhere so will hunt it out and update to include both. Quote Link to post Share on other sites
markm 30 Posted July 3, 2019 Share Posted July 3, 2019 Now updated. My those 930s are quick, best hope no handicappers are looking at this. Quote Link to post Share on other sites
splat 55 Posted July 3, 2019 Share Posted July 3, 2019 Ahh that explains it...only skimmed it. Quote Link to post Share on other sites
Fish 0 Posted July 4, 2019 Share Posted July 4, 2019 Why do those look slow to me? I'm very surprised that no Elliot or Young boat owners have offered their thoughts to this question of why Ross polars look so slow... Quote Link to post Share on other sites
Y88 Association 8 Posted July 4, 2019 Share Posted July 4, 2019 We like the expression ... "the rising tide lifts all boats".. 88s have great tussles with 930's especially upwind. The turbos are harder to hang onto and off the wind in a breeze a 930 will surf right on by. Thread steal..... @MarkM, if you have some up to date 88 polars I am sure they would also be gratefully received? What we have in the Young 88 Google Drive is from our friends at SailOnline Quote Link to post Share on other sites
markm 30 Posted July 5, 2019 Share Posted July 5, 2019 Have info for Pistol Dawn, Young at Heart and Venue www.racetrack.org.nz/XLS/young88.xlsx Quote Link to post Share on other sites
Fish 0 Posted July 5, 2019 Share Posted July 5, 2019 Is the bump to do with sail polars? The transition from head sail to gennacker to spinnaker type of thing? Sailing too deep with a gennacker is slow, sailing too high with a spinnaker is slow kind of thing? There is an optimum speed and angle for every sail, which is reflected in the boats overall performance polar. 1 Quote Link to post Share on other sites
vic008 17 Posted July 5, 2019 Share Posted July 5, 2019 Whats happening to CC? Is he crook? A lovely bloke. Quote Link to post Share on other sites
Fish 0 Posted July 5, 2019 Share Posted July 5, 2019 DOH!!! Yes of course that makes perfect sense, unusual in your case but hey every dog has their day I've been having one of those days and I should have got that myself. Maybe stressed about all the boating tomorrow, a lot on and all of it wrangling sails boats not on one, bummer! Gee, looks like I'm starting to make a habit of making sense, who whaddathunk? Your not going to play with guns tomorrow as well are you?....................... Quote Link to post Share on other sites
S.M.U. 15 Posted July 5, 2019 Author Share Posted July 5, 2019 Thanks for the info. So now have some R930, Y88 and Far East 28R polars to play with. Quote Link to post Share on other sites
