That's what you get for attaching pages and pages of unsharp hard to read print : I can't even find 3-48 !

A restoring moment (as the term is used in this text) is a moment that tends to oppose the tilt of the boat. Since the boat is tilting clockwise, as viewed, a restoring moment is necessarily anticlockwise. As the diagram shows (3-46, not 3-48), when the moment reinforces the tilt it is called an overturning moment.
Your own diagram shows the boat tilting anticlockwise, so yes, in that case a restoring moment would be clockwise.
