The Charles River Alliance of Boaters (CRAB) is a coalition of individuals and organizations that use the Charles River from Watertown Square to the Charles River Dam. Our mission is to encourage safe and accessible boating by the entire community on the Lower Basin of the Charles.
CRAB organizations are your access to organized boating on the Charles River.
They are public and private, non-profit, for-profit and school based, and offer a wide range of boating experiences for all boating interests from sightseeing to Olympic training. Whether your interest is with an oar, paddle, sail, motor, or even helping to keep the river clean, CRAB organizations can provide what you need.
In bringing together power boaters, sailors, rowers, paddlers, and others, we can work together to keep the Charles River a healthy resource for the enjoyment of boaters and park users alike.
A cornerstone of our effort is the development of better avenues of communication between and among this diverse community of users.
While here, don't limit yourself to just your favorite activity. Take a few moments to learn about what other people are doing on the Charles.
This web site is intended to be a resource for all the users of the river, including people that are just thinking of getting on the water.
There is a separate page for each of the major groups of users: rowers, sailors, paddlers (canoeists, kayakers, paddleboarders, and dragon boaters), power boaters, fishermen, sightseeing providers, and stewards of the river. On each of these pages, there are links for useful information, including traffic patterns and other safety information. Also on each page are links to organizations that provide recreational and competitive opportunities.
To the right of every page are useful links for that activity. Here, there are links to our blog, our calendar, our contact list, as well as our activity advisories.
With 13 rowing clubs, 4 sailing pavilions, 4 yacht clubs, and several other stakeholders on the river, we don't meet off the water very often.
Most of our communication happens via email to representatives of each river organization.
CRAB emails weekly notices about activities on the river as well as other occasional notices and requests.
CRAB has two separate email list-servers, a private one for club representatives and a public one for river users and the general public.
If you'd like to join the public list-server and get these emails directly, please subscribe.
CRAB will not share your personal information and you can unsubscribe at any time.
While we try to communicate by email as much as possible, hardcopy mail can be sent to CRAB, 20 Nonantum Road, Brighton, MA 02135.
