Regarding comparisons of the fictional SWALLOW and AMAZON as to their sailing ability, let me quote a few lines from SD CH35, the race around WCI and back to Beckfoot. It shows a difference as to how they manage a good wind.

----------

"They'll get smoother water that side of the island," said
John to himself, "and smooth water suits Amazon best. But
there's more wind outside and Swallow wants all she can get."
-----

A black patch of wind-combed water was sweeping down the
lake marking the track of a squall coming down from the
mountains.

"They'll be getting it first," said Susan.

"Amazon won't like it," said John. "She's not as stiff as Swallow.
Besides, all together, we must weigh more than them. Look, she's
feeling it already."

They saw the little, white-sailed Amazon, far out in the middle
of the lake, heel suddenly as the squall struck her. They saw her
luff and come up into the wind with sail shaking for a moment.
It filled a moment later, but again she heeled over and again she
came up into the wind.

"They've got all they want," said John.

"We'll be having it in a minute," said Susan. "Here it is."

"Hang on, Susan. Don't ease unless you have to. She'll stand it
all right. Keep her down to it. Good little ship."

The squall whistled down on them. Swallow heeled over,
picked herself up, and shot forward, the foam spirting from
her bows. There was not need for her to come up into the
wind. She was glad of the whole force of it to send her flying on
her way.
---------

Looks like Nancy understood the possibility of instability in sudden gusts of wind, and rather than using the wind to shoot the ship forward faster, she has to spill some of that wind by heading a bit more towards the wind source. I guess that comes from practice, knowing her ship.
