BRV does not sponsor kayak rolling sessions, so check out the links below. For canoe rolling, the best bet is to find and old Bob Foote video, ask a capable open boater, and ask around on CBoats.net.
If you do not know what rolling your kayak or canoe means,
you likely need basic whitewater instruction.
Canoe Cruisers Association offers an exceptional, low cost
instructional programs during the summer months on the Potomac River.
