Reports Reading Guide

Race Area

Start

With just 6 degrees of bias (which is not so easy to notice) and such a long start line, there is already more than 50m of upwind distance between the ends of the line. The wind at the start is set based on the courses the boats sail on both tacks after the start. 6-degree bias is the one that is good to remember since it creates exactly 10% of line length upwind distance advantage. So for 550m, there is approximately 55m of difference. With such a long line, as soon as bias is noticeable, you need a very strong reason not to go for it.

The same boats were called over by RaceSense

1st Upwind

There were a few shifts in the upwind that could be played. At the very end of the upwind, there was pretty strong left shift that has pulled the boats on the left side forward. No Dramas and MagPie won a lot there. Boats starting closer to the pin end were gaining a bit also on the way to the left. Fumanchu leading for the most of the leg, but lost to left boats at the end.

  1. RC boats headed after the initial lift
  2. Big left shift favoring the boats arriving to the top mark from the left.
Suggested wind direction shifting a bit and then going hard left
Clean upwind sailing, no maneuvers or roundings

Top Mark

Top mark 100m to and from stats. Note that No Dramas didn’t round the gate

1st Downwind

Lisa and First Tr were the only one matching the leading Fumanchu on the 1st downwind. Gybe setting HKG1382 and Aus1463 were gaining after the initial gybe-set loss. Especially HKG sacrificing lots of meters at the beginning of the leg. Jindivik dropping the most meters in the front pack.

Gate Rounding

Huge gate bias. This is a game changer in the race and the windward mark just has to be taken. Just look at Blue and Black boat rounding. Magpie gaining a lot on First Track.

50m to and from stats. Fumanchu gave 19 seconds to First Track. All the boats doing the right turn have lost a lot. First Track sailed 36 more upwind meters of sailing to get back to the same place than Fumanchu.

2nd Upwind

The key was to go left with the initial lift and then play the shifts on the way to the top mark. The leaders did a good job at this with MagPie catching shifts better at the end to overtake Fumanchu.

Nice lift for the boats going left in higher lane and then the greenest were the boats playing the shifts on the way to the mark
Clean sailing numbers. No maneuvers and roundings
