Data fields:
Time: duration of selected sailing
Dist: distance sailed
Updist: distance sailed in the direction of the set wind
Mans: number of maneuvers and total loss in them
SOG: speed over ground
VMG: speed in the direction of the wind set
ATW: angle to the wind set
Heel: heel (L/W, degrees)
Heel Tr: travel of the heel in degrees per minute (stability of the boat, lower numbers are more stable)
Course: bearing between the 1st and last point of the selection. Used mostly only when need to see the shifts, when a straight line segment is selected.
Race Area
The race area was set at the same place as race 1. It was still skewed to the right from the wind direction. The right side of course is covered by land and therefore probably not the place to sail.
Another reason why the left side pays is that the wind hits the land below the start line and on the east side of it. Wind hitting the land directly usually decreases while it piles up on the land. I don’t know the exact configuration of the leeward shore, so cannot estimate how much it blocks the wind. While the left side of the course has the wind flowing freely to leeward shore in the distance and lets the wind pass easier.
Start
The wind direction was a bit more right than in the first race, so the pin bias was smaller.
I-7 went back after the start. The app shows the tracker 2m behind the line, but the RC and pin position were set manually, so not full accurate. If I-7 was over the line, most probably I-760 was too since they were even a bit in front. Of the other boats, I-14 had the worst start at 25m to the line. I-414 and I-12 were also quite behind.
1st Upwind
I-96 was gaining in the first 2 minutes of sailing, having done the highest amount of upwind meters and went from -5m to the leader to 2m in the lead.
Once again, the skewed course proved to be an important factor. I49 and I55 ended up too far in the corner and since this race was also about playing the shifts, they had no room to play any of the shifts anymore. They also had a header coming on the way to the left on which they didn’t react. So like this, they ended up behind the boats above and with no options left in case they got covered. I-55 got heavily covered and suffered all the long way to the mark. I 49 tried to tack but had to tack back. If the plan is to go toward the top mark, they should have ducked and shot through. Leeward position on the long way to the mark could be a strong place to be.
I-96 was doing good on the way to the left. They tacked and ducked I-760 and ended up below on the way to the mark. Ducking a boat means that you are most probably in front of it once the ducked boat tacks, so is always a good move, better than waiting and ending up over the layline. So I-96 was in the lead on the left side.
I-760 and I-210 had a nice lift on the way to the left, but after the tack have lost some meters to I-96.
I-414, on the other side, was using shifts after the bad start and gained to everyone.
I-14 also played a few shifts. However, just at the mark approach, they tacked too close behind the boat in front of them and didn’t lay the mark. A few meters more before the tack there always is a better option to be safe. This way I-14 fell to the stern of the boat in front and fell below the mark. They also forced I-210 to tack so they both lost quite a lot.
I-7 sailed some solid shifts at the end of the upwind and has caught up a bit on the group.
1st downwind
The first four boats got a nice shift and gust to go lower. I-210 and I-49 ended up pretty high and in a vulnerable position after the gybe. Close to the corner, the leading boat was slowing down and the fleet compressed a bit. Looks like there was more pressure behind. So I-414 gybed on top of the leading I-96 and managed to roll them. Also, I-14 and I-7 used that to gain on the opponents.
1st LW Gate
The leeward gate was again a lot biased. It was more than 30m of upwind distance difference, meaning that the boat that goes to the leeward one needs to do 30m of downwind sailing and then 30m of straight upwind sailing just to come back to the same level where the favored gate is rounded.
2nd Upwind
After rounding the mark, I-96 sailed in the header, and after the tack lost quite some meters to I-414 and I12. It is clearly visible that I-49 and I-210 have sailed much higher course after the mark rounding.
Looking at the 1st upwind typical course on the starboard of I-96 was 178degrees. After rounding it was 168degrees and they have sailed like this, in 10 degrees header, for many meters. After the gate, it is crucial that the course gets said and compared to the previous upwind so that the boat gets into a good shift rhythm. They have missed this and have lost a lot.
I-210 has lost all the gains by sailing long port tack behind two other boats. I-14 had some strange tack in a big lift at one point. Otherwise has played the middle quite OK.
I-414 used the shifts and stayed in good control. I-12 got a big left shift after the gate and has managed to tack just in front of I-96.
I-7 was in the back and ended up doing the fastest 2nd upwind of the fleet, followed by I-49.
2nd downwind
2nd downwind shows a bit more right wind direction than before and also early gybes were paying. So I-49 has caught up on I-96 and I-12 and also I-14 has gained on its group of boats. Apart from I-414 which had by far the fastest leg, those two were the best. I-55 could only do 7.5kts of speed and has lost a lot.
2nd LW Gate
Not to repeat already mentioned, just look at the DTL graph drops of respectively blue, black, red, and brown boats. Note that the graph scale is in hundreds of meters just to realize how significant the losses are.
3rd upwind
Very interesting is the comparison between the different modes of three boats I-12, I-96, and I-414 on starboard tack after the gate rounding. each of them sailed pretty different wind angle, but in the end, their VMGs were almost identical.
Speeds were in a range from 6.67kts of the slowest I-12 to 8.04kts of the fastest I-414 and angles went from the highest of 33.10 of I-12 to 45.03 of the lowest I-414. Their VMGs were 5.59, 5.61, and 5.62. You can also see the three sets of dots in a polar graph at almost identical height up the screen.
I-49 and I-210, however, sailed pretty low, but with not much-increased speed and were losing to the other three boats.
The wind was in almost 10 degrees more right values than in the 1st upwind, probably changing the game a bit. An interesting battle was between I-96, I-12, and I-49 with a close finish at the end of the leg.
A great job was done by I-7 which has had the fastest last upwind together with I-414 and almost caught another boat after a huge loss at the start.
