NEW boat reports available!

Interested in only your boat? Go to the leaderboard and click on any boat name. A window will popup w/ the latest track for only your boat + all the obs along the way.

This doesn't subsitute for the data download -- this was mainly in response to having something printoutable for the competitors when they arrive at the finish line.

Comments welcome!

Looks great.

Will be very handy. Would it be easy to resort the positions so the most recent position is at the top of the table?

Also, maybe the start-time needs to be reset now to the actual start-time.

Great idea. Done.

And those are the true start times I've been given. 2 of the classes started at later times (e.g. non-spinnaker), but most were at 8:30 EDT.

Picky, picky, picky, we just want everything, don't we?

Looks great, but it would be nice to have a Distance to Go "DTG" column.

They may want some other data for a final printout. Especially a finish time, which they would have to furnish you, or they could dump your data into a spreadsheet and just add that column for finish time.

It looks like an acurate start time is hard for you to determine other than getting data from the race committee on each official start for each boat. Once you had that, you could plug in the official start location for "boat position" L/L, time of start.
From there you could add a column for "HDG" heading, "SOG" speed over ground, because it isn't really boat speed, is it?
In other words, if they were doing 12kn on the boat against a 2 kn current, you would only show them doing 10kn, right?

Now for really hard core analysts, it would be neat to have a distance between each position report and then add it up at the end to see who sailed the shortest distance. The official race distance on the Rum Line is something like 456km, which would be impossible to do, with wind and current set, heading changes, etc the true distance sailed would be more like 75 to 100 miles further.

Does your transponder take any data other than just heading and position, like a flux gate compass?
Will they eventually try to include true boat speed thru the water and true wind dir and speed? It would mean a lot more electronics for some boats, but possibly you could tap into existing equipment that the boat already has.
That way the captain could sit at home and direct his crew on what heading, etc, just like remote control, ha.



Great job......

I have been watching both sources, mapping and leaderboard and they don't seem to be in sync?

On the map it shows Relativity roughly at 22 / 86 which agrees with the leaderboard, however, the LB shows 1.22nm distance and the Map shows 53nm?
Same with Mango Lat, LB shows 0nm, does this mean they finished? Map shows 56nm?


see ya.....

The leaderboard dist. to finish is interpolated and is computed based on the average speed of the boat over some period of time (I can't remember offhand). So it is most likely to show boats finished before the transponder actually reports it. Otherwise, the leaderboard would be whacko w/ things updating at weird times.

Once the race comm. reports official finish times, I'll plug them into the system, and things will be locked into place. And there is a spot on that report for a finish time -- they just need to furnish it before I can post it!

I misunderstood the original start times, so on the next db sync, things should be updated OK.

TC A, B, & C started at 0851. The spinnakers and non-spinnakers started at 0858.

I can add the dist. from finish, but I'll hold off on all the other computations for now -- although since we have the data, it shouldn't be a problem.

Thanks for the feedback!
