Is the area of a mast stub (and any gooseneck mounted on it) included in the measured rig area?

Answer

A combined stub mast item and gooseneck that supports the mast spar is a component of the rig but it is not a spar according to the ERS definition F.1.1. It is not rigging, spreaders or corrector weights so the conclusion is that the mast stub and the gooseneck are fittings. Providing fittings are not larger than necessary and are not faired into a spar (CR J.1 (b) ) there is no requirement to include their area in the measured rig area.
