As the Organizing Authority, US Sailing has certain tasks it manages. Event hosts are responsible for others.
As a host of a national championship, you are responsible for all of the “on shore” elements. The national chair is responsible for the “on the water” elements; however there is always some overlap.The host includes the national chair in its planning meetings at least monthly so that communications flow smoothly for both the on and off the water elements throughout the planning process.
