しかも今回は風の入りも良く、タック直後に約0.8ノット上がっています。

Here's a big knock. Tack on a knock to get a corresponding lift on the new tack...

And, in this case, a bump in pressure, too (Note the 0.8 knots gained after the tack)

タックするたびに、1艇身、2艇身……とロスが出ることは珍しくありません。
そのタックが

- 戦略的な判断だったのか
- 戦術的な対応だったのか
- それとも風のシフトに反応した結果だったのか

その“投資”(ロス)は、本当に価値があったのでしょうか?
その答えを知るためには、まず 「どれだけロスしたのか」 を正確に把握する必要があります。

You lose "x" boat lengths on a tack or gybe. Is the investment worth it?

You won't know if you don't first know what "x" is.

“Air behaves like a liquid.”

Looking at the right shift along the southern edge of the island here, followed by a sudden lefty, you can easily picture how the air “pours” around the obstruction.

Course layline vs. wind layline...

Based on the course laid, it looks like the sailor has overlaid by a long way after tack 2 (Course laylines shown in yellow).

Windii's algorithm automatically shows the wind laylines as well (white).
