'A' Ocean category is one of the following:-

Design categories (as in the amended Directive)

Category A - Ocean: Designed for extended voyages where conditions may
exceed wind force 8 (Beaufort scale)
and significant wave heights of 4m and above but excluding abnormal
conditions, and vessels largely self-sufficient.

Category B - Offshore: Designed for offshore voyages where conditions up to,
and including, wind force 8 and
significant wave heights up to, and including, 4m may be experienced.

Category C - Inshore: Designed for voyages in coastal waters, large bays,
estuaries, lakes and rivers where
conditions up to, and including, wind force 6 and significant wave heights
up to, and including, 2m may be
experienced.

Category D - Sheltered: Designed for voyages on sheltered coastal waters,
small bays, small lakes, rivers and
canals where conditions up to, and including, wind force 4 and significant
wave heights up to, and including, 0.3m
may be experienced, with occasional waves of 0.5m maximum height, for
example from passing vessels.

Craft in each Category must be designed and constructed to withstand these
parameters in respect of stability,
buoyancy, and other relevant essential requirements listed, and to have good
handling characteristics.

To my knowledge, the only power-cat builder in N America to achieve  EU RCD
category status is PDQ.
That is not to say that others would not achieve the same - it's just that
they have not.
