While on the water drinking fluids is especially important. Remember to bring extra water on the boat with you. We recommend you wear light, loose fitting clothing when you visit. Sunscreen and hats will protect your skin from the sun.

If at any point you feel overwhelmed by the heat, please do not hesitate to request a ride back to the dock. Lower your sail halfway, call 617-248-3850 (Option 5) , or hail “CBI” on marine VHF 72.

Please note we will be rotating our staff through frequent rest breaks for their safety. As a result staff presence may be less visible than normal around the dock. As usual, Dockhouse will always have a staff member available to provide assistance.

Safety Launch Operators will periodically circulate on the river to offer you water.
