Hotlaps 2013 is a sail racing format that lets sailors practice their skills by doing solo laps on a standard ‘test track.’ Skippers can then upload their ‘average, good‘ lap times to a spreadsheet that compares their results against other sailors and across different boat classes.
This round of Hotlaps is just getting going, but so far the response has been great and there’s lots more planned.
In just the first two weeks, 28 skippers entered 140 lap times for 24 different boats. The current list of Hotlaps sailors is shown on the right, and the ‘Color Code’ is a key to the lap times listed on the spreadsheet below (as well as on the pages of the active spreadsheet here).
There are five Hotlaps locations so far: Plum Gut, Breadnut, Linkous, Knaptrackicon, and Sulu. There is a notecard over the raceline at each spot that will give a Hotlaps chart, database links, and any specific instructions.
So far, Plum Gut turns out to be the most popular Hotlaps location, with 88 lap entries. I’ve included a snapshot of the Plum Gut summary spreadsheet below. Click on it to get a bigger table that’s readable.
So far at Plum Gut seven sailors have contributed 15 laps sailing the Melges-24 “index boat.” The results are pretty consistent, with an average lap time of 8:59, and a standard deviation of 0:24. Fearless Freenote at the moment holds the speed record in that class; he logged a rather amazing 8:18 two days ago, edging out Armano Xaris’ prior time of 8:32.
Speaking of speediness, Fearless also showed that the lap time for the WildWind VO-70 is substantially faster than the new Mesh Shop VO-70. Many sailors guessed that was prolly the case, but it’s nice to see that Fearless nailed it. You can see the actual numbers in the table below.
Hotlaps isn’t just about speed though. The lap scores also help generate relative performance factors (a.k.a. “Handicaps“) that compare boats to an arbitrary standard (the Melges-24 is that index boat).
The table to the right lists the current set of handicap factors determined by lap scores at each of the five racelines. In general, all the racelines produce the same handicap rank for a given boat, but there’s still variability in the the actual handicap numbers. That should settle down as skippers sail more laps on all the lines and add their results to the mix.
Nonetheless, the present handicaps have a number of interesting results. For example, Slanty Uriza nicely showed on the Sulu line that the vernerable Tako 3.3 is a close lap-match for the new and shiny Melges-24, and both boats are roughly equal in speed to the ACA33 3.0.
We’ll see how well those numbers stand up in the coming weeks.
Oh, and don’t forget:
You got ten minutes?
You could sail a Hotlap!
