Nope, sorry. You can tell that it's wrong, because if you put 265° under the index and 59 kt under the centre dot, the wind mark gives you a right drift of 30°, which means that you are tracking 265° + 30° = 295°, instead of 300°.
This is how I did it with the wind-down, initially putting 300° under the index:
1) tentative drift = 19° --> heading = 281° --> new drift = 26°
Not good: old and new drift don't match, and indeed, if we steer 281°, we drift 26° to the right, that is we track 307°, instead of 300°. So let's try again with 7° more of drift correction:
2) tentative drift = 26° --> heading 274° --> new drift = 28°
Almost there, but if we steer 274°, we drift 28° to the right, that is we track 302°. Let's repeat adding 2° more:
3) tentative drift = 28° --> heading 272° --> new drift = 28°. Nailed.
The TAS then turns out to be 56 kt. I've double-checked with the wind-up method (in one step, of course
) and the result is the same.
