where
a

line
through
a
tilted
vessel's
center
of
buoyancy
intersects
the
originally-vertical
(but-now-tilted)
line
that
passed
through
the
center
of
buoyancy
when
the
vessel
was
upright;
it
must
be
above
the
vessel's
center
of
gravity
for
the
vessel
to
have
positive
static
stability
(to
tend
to
return
to
an
upright
orientation
if
rolled
to

side,
rather
than
to
continue

Quizzes for review
(physics, nautical) The point where a vertical line through a tilted vessel's center of buoyancy intersects the originally-vertical (but-now-tilted) line that passed through the center of buoyancy when the vessel was upright; it must be above the vessel's center of gravity for the vessel to have positive static stability (to tend to return to an upright orientation if rolled to one side, rather than to continue rolling to an inverted orientation).
