the accelleration needed is 1/2 g

1/2 G (note the capitization) means a 11,000# strain on a 22,000 # boat.

Capital G is the universal gravitational constant. Lowercase g is the
gravitational accelleration constant, the constant describing the
force which accellerates a mass towards the Earth's center as measured
at the Earth's surface. g is not constant everywhere on Earth because
Earth is spinning and because Earth is not a perfect sphere.

When one discusses forces on a body, one may compare these forces to
the force due to gravity, because gravity is familiar. A 2 lb mass
experiences a 2 lbf downward force from gravitational attraction on
Earth, thus a 1/2 g force (note lower case) would equate to 1 lbf. It
would not be possible to know what a 1/2 G force would be without
knowing the mass of the planet and the distance from the center, which
is why g is typically used instead of G since g already has that
information factored in.

you
got 11,000# chain/chocks/anchor on your boat.
btw, yo-yo, the G-loads can be one hell of a lot higher than 1/2.

The issue is indeed over the forces and whether the anchoring is
designed to withstand them and/or to minimize them.
