Yeah, I can imagine in a class fleet it's not going to tell you anything that wasn't pretty obvious on the water. But implemented well I can see it going some way to giving the feedback on your performance that sailing in a fleet does.
If they had mean wind direction, and tacking angles, then they could tell you how many meters you cut off a beat by tacking on the shifts. And by moving to heat maps plus a handful of selected tracks would make the playback a bit more watchable. I'd go to handicap race, not fussed about results, but if it could give me some analytics on my performance that otherwise I'd only get from sailing in decent sized fleets. Basically if they could get to a nice version of RaceQs I'd much rather that. However, I kind of feel that the type of GPS needed to get the accuracy in telemetry is a bit more costly than what can presently be rolled out. Like... I travel a decent way, and pay a decent amount to have one of these on my boom for the day, regardless of results. |

The issue to confront is that even in IMS yachts, which have speeds that vary much less than dinghies as conditions change, using a handicap that varied according to windspeed and direction is extremely problematic and I think it's been abandoned after many years of intensive effort. They tried doing things like "implied wind" scoring (which was sort of like back calculating what the wind must have been based on the relative performance of the boats), having a powerboat in the middle of the course measuring windspeeds, looking at inputting tides, taking figures from the wind instruments on selected competitors, using predictions from the weather bureau, etc. Basically none of it satisfied people. So the first thing would probably be to read up on old Seahorse magazines and other sources, see what has been tried and why it failed, and then try to work out where dinghies could succeed where yachts with fewer lumps and bumps on their performance profiles, more money and lots of instruments and normally sailed in more open water, failed.

The SAP tracking at the 505 Worlds has pretty much every detail you need to work out where you were right or wrong, but would be cost prohibitive for most events I would think.

Agreed sap tracking is way superior. Good laugh for trying to understand why things happened on the course. Costs as much as a mercenary army I expect. Makes no attempt to give everyone a prize for some facet of their race in a modern snowflake manner. Chris 249 is bang on about the ims. Sadly I threw out my early to mid 90s seahorse as part of domestication. Py is the least imperfect way of going non od dinghy racing, any attempts to hop it up just mystify it. Nobody watches this sh*t anyway it’s a sport for participants. Like angling. If you dislike py enough to do it at club or open level then you don’t like sailing enough, and I expect don’t do much of any variety anyhow. Plenty of instances of rating band scrap racing working over 40 pt ranges also, as individual ability usually is a far bigger factor in performance until you get into the top 1 or 2 percentages of the bell curve at national level. |

You must be kidding; fishing on TV is massive with loads of content and channels ... |

certainly for spectators at the venue and interested parties away from it this form of tracking is good, it could be better, but modern equipment allows for live broadcast on several channels like fb and youtube and along with mobile phones on ribs doing the video bit a half decent live broadcast could be made of these sorts of events and OD events too, requires a small team dedicated to it and signal.

For those looking to find out more about the Great Sailing Challenge, Andy Rice and I will be hosting a webinar tonight (19.00)
There is the chance to ask questions, both live and in advance.
