The show celebrates sailing, boating and all types of marine sporting lifestyle.
In the Craneway, vendors ranging from diesel engines to autopilots to clothing to publications to solar panels have items on display and for sale.
Seminars on all manner of concern to boaters - and those wishing to become boaters - run each day.
At nearby Marina Bay Yacht Harbor, new power and sailboats are on display also.
"We are thrilled to have so many exhibitors, new boats, products and interactive events to involve the community this year," Katie Kelly, Sail America's Association Manager said.
"Attendees will find the latest boat communications technology, boats, and solar panels."
In addition, there are a number of younger participants and activities this year including special events put on by Groundwork Richmond's environmentalists and the West Contra County Sea Scouts. Groundwork Richmond will be teaching kayaking. The West Contra County Sea Scouts will be instructing in rope knotting.
Today free standup-paddle board lessons are being offered by 510 Waterline until 1 p.m.
Also today, at 6 p.m. Cruising Outpost will hold a party and raffle to raise funds for Call of the Sea, an organization that works with the Educational Tall Ships Foundation Project in Sausalito.
