On some race craft I notice a bag skirt underneath the hull running from one side to the other, whats the purpose for that? Is it for more stability? If so hows it fed with air?

It is to create a high pressure area at the front of the craft to help stop ploughing in. Some craft have one cross bag, some use a 'Y' shape and some use a 'T' shape.

The bag is usually fed from the nearest feed hole.
