Reports by SailViewer App, logs tracked by Vakaros devices
SailViewer app is even more powerful once used by a single team to analyze their own sailing, answer their own questions and compare themselves with others. It is made simple, to be used by the actual sailors or coaches that were on the water.
Race Area
The race area was set with the top mark set more than 10 degrees to the right then the wind direction. This means, with boats that sail approx upwind angle of 36, they will sail almost double the time on port than on starboard tack. So, even though it looks like the left side was the place to go, you need to think about early tack to the top mark, not to overstand it.
Start
The start was set with some pin-end bias, which with the left side paying made it significantly better for the boats at the pin end. Note that the line is set manually based on the position of the boats at the gun and just keeping everyone behind the line. There were no RC or pin boat coordinates provided.
Even though I-7 was the closest to the line, it had 9m of disadvantage to leader I-49. Looking at the 1-minute distance to leader numbers, there was clear gain by the leeward boats.
1st upwind
Pin-end boats have clearly pulled out on the way to the left. I-14 and I-210 struggled to keep an angle and were falling to the sterns of boats to leeward. I-760 and I-12 on the windward side were clearly slower, probably with less wind. The worst time had I-55 with only 5kts of average speed.
But, as it often happens, getting to the front was not the only thing needed. Since the course was skewed, the layline came soon and I-7, which was forced to tack away has made it exactly to the top mark. It is always crucial to check the position of the top mark to the wind direction. In a class with high angles like Scow, this means that the layline can come pretty soon. Also, there was a huge left-shift curve happening toward the top mark. I-14 had a huge lift on the way to the mark, arriving almost to the top mark. It sailed about 170m less distance than the initial leader I-49
I-55 and I-210 had very difficult times at the middle of the course, not having such nice angles. I-210 sailed on average 10 degrees lower.
1st upwind
1st Downwind
The leader seemed to have a good breeze after the rounding and was going pretty fast and low. 2nd till 4th boats were forced to go much higher and slower, allowing the boats from behind to catch up on them. I-14 was gybing twice, after getting rolled by I-49 and still ended up crossing just in front of it. The skewed course was forcing the boats to sail on longer starboard tack first and early gybe did not pay.
I-96 has gybed exactly at the layline. Boats passing behind it could have seen that it goes straight to the gate, still many continued and ended up below the layline. I-14 has lost the most by going furthest.
The compression can clearly be seen as I-210 has sailed the fastest downwind, not counting the leader. Also, in the colored paths the initial loss after the hoist is visible for the leading group of boats.
LW gate
The leeward gate was very biased, with I-12 sailing to the mark that was 31m below the other one. This resulted in a huge loss, as it was just about to be equal to I-414. As soon as the bias can be clearly visible by sailors approaching the mark, it is always big enough that it should be taken.
I-12 started the upwind leg 31 meters below
Huge DTL drop by green I-12
2nd Upwind
The 2nd upwind was much trickier and shifter than the 1st one. I-7 has started it with the loss since the boats behind got lifted a lot. However, even after losing quite some of the lead, they still kept cool and covered the boats behind.
I-414 has nailed two great shifts and has climbed up, which can be seen as the yellow line going up in the DTL graph
Showing that the race area was much more open is a solid gain by I-760 from the right side, catching a huge right shift.
This could be due to the wind bending around the shore.
2nd downwind
The last downwind was also pretty gusty and patchy. By gybing early, I-414 initially gained but lost it after gybing back, being forced to sail much higher angle.
After the initial loss, I-14 has gained quite some meters back through the middle of the course. I-760 lost both them and I-12 that gybed early.
Other than this, there were not many places changes in the last downwind
