USOA is the sanctioning for underwater sports in the USA.
It is a charter member of the World Underwater Federation (CMAS).  As a member of CMAS, USOA sanctions yearly local, regional and national under water championships in skin diving, underwater hockey, underwater rugby, fin swimming and spearfishing.

Welcome

This is the new USOA website.  The new format will be more accessible for membership, event registration and information. Each club has their own page under the sport.  Dues and waivers for each club can also be collected here.  There is a need for a volunteer from each sport and club to oversee their information.  Please let us know what you think and what you would like to see.
