This is much easier in boats like 49ers and 49erFXs, where you have full-battened mains. Those boats can stay really stay still, and you can crab and go sideways. A boat like a 470 is more difficult because the boat doesn’t want to sit. To hold position, you have to work really hard—roll the boat, tack, or scull. We do the same drill in in J/24s, Melges 24s, and J/70s. Heavier boats, such as Etchells, are a little tougher because they keep their momentum so easily. The distance from the mark really depends on how long it takes the boat to accelerate. In an Etchells, the stationary position might be 4 to 5 boatlengths below the line because it takes that long to accelerate. On the other hand, a 470 it takes a half boat length to accelerate in any breeze, so two boatlengths is not a problem. In J/70s in 10 to 12 knots of wind, we do two boatlengths. Same drill. When it’s windier, it gets more difficult to hold position.
