Question 1970 Deck Safety

The correct answer is D) deck line. Freeboard is measured from the upper edge of the deck line, which is the line where the deck and the hull of the vessel meet. This is the point from which the distance to the waterline is measured to determine the vessel's freeboard. The other options are incorrect because: A) The sheer strake is the top strake of the hull, not the reference point for freeboard. B) The bulwark is the vertical extension of the hull above the deck, not the reference point for freeboard. C) The gunwale bar is a structural element of the vessel, not the reference point for freeboard.
