Haven't sailed there, but have run powerboats
there alot. I usually launched from Windsor Beach in Lake Havasu City, AZ. Upper part of the lake is shallow, the channel into the Colorado is usually over on the California side going upstream. The lower end of the lake is deep and more wide open, some very pretty areas. Unfortunately seems like the winds are usually pretty extreme, either glassy or blowing like snot. The section of the Colorado upstream of Havasu thru Topock gorge is like a mini grand canyon. If you got something you can launch at Moab State Park on CA. side and drift down at about 5 to 6 knots, great for canoes, small powerboats etc.
