Every sailor in your program can tack. They do it in practice, they do it in drills, they do it when you ask them to. It looks fine. It feels like progress.
Then they get into a race. Boats around them, a layline decision to make, someone coming in hot from the right. And the tack falls apart.
This isn't bad luck. It's the difference between a skill that's been practiced and a skill that's been learned.
What practice-level looks like
A sailor who can tack has figured out the sequence. They know the steps. In a controlled environment, with time and space, they can put it together reasonably well.
But that skill is fragile. It requires attention to execute. The moment something else demands that attention — a competitor, a wind shift, a tactical decision — the tack suffers. The sailor can't do two things at once because the tack still takes up most of their mental bandwidth.
What learned looks like
A sailor who knows how to tack doesn't think about it. The movement is automatic. It happens while their attention is somewhere else entirely — reading the fleet, timing the layline, watching the pressure on the water.
That's the standard. Not a tack that looks good in practice. A tack that holds up when everything else is happening at the same time.
How you get there
There's only one way. Reps. Not a few reps — a lot of reps. The same movement, over and over, until it stops requiring conscious attention. Until the body just does it.
This can be uncomfortable if you've built sessions around variety. It means spending more time on one thing than feels necessary. It means running the same drill past the point where it feels productive.
But that's exactly where the real learning happens — past the point of feeling productive, into the territory where the skill becomes automatic.
The racing test
The simplest way to know if a sailor has truly learned a skill is to watch them use it under pressure. Not in a drill. In a race, in a tight situation, when the outcome matters.
If the tack holds up there, it's learned. If it doesn't, it needs more reps.
That's the standard worth building toward.
