Following the guidelines on social distancing and consulting with our safety experts, we are not able to host the July 10th Boston Harbor Relay. Because of the number of participants and volunteers who are on a boat for an extended period of time, rescheduling the BHR for 2020 isn’t an option. Stay tuned for how to support SAA-Boston in 2020!

Relay Schedule

Schedule is tentative and subject to change.

Swim begins at 7:00 am from Rowes Wharf and travels out to the Boston Lighthouse and returns back to Rowes Wharf.

Approximate duration: 8 hours.

Each heat contains 5 - 8 swimmers. Swimmers serving as alternates will be available throughout the day for substitutions.

Heats have been arranged according to swimmer’s 500 yard /1 mile freestyle times. It is important for each swimmer to know his /her assigned heat number. The heat order may change throughout the swim to handle the varying conditions. For instance, the conditions or time constraints may require the substitution of a stronger heat.

Heats run consecutively and are approximately 15 - 20 minutes in length.

Relay Procedure

Start: Olympian swimmers [5-8] begin from dock at Rowes Wharf

  • Navigation boat positions 50 yards off the dock.
  • The Boat stands off ahead of the navigation boat until the swimmers pass, and then fall into formation behind navigation boat and along side the swimmers to position themselves for the first transition.
  • All heats, except for the first heat of the day, will begin from the boat
  • All swimmers are to follow the navigation boat (bright orange buoy off the back). The navigation boat is setting the course and will alter speeds for each heat. If any distance develops between the swimmers and the navigation boat, chase boats will be very close to monitor the swimmers.
  • After the designated heat time, a “finish line” 2 Zodiac chase boats will leave their safety net positions behind the swimmers and come along side each boat for pick up and transport back to the swim team boat.
  • At the sound of the air horn, swimmers will enter the water from the alternating boat and swim towards the navigation boat as directed by the boat captains.
  • Heats end and the new heat begin as the first swimmers of the previous heat touch the “finish line” chase boat and the horn sounds.
  • After completing the heat, swimmers will board a chase boat and be returned to the team boat.
  • While the recently finished swimmers return to the team boats, the new heat of swimmers has entered the water for the next leg of the swim. Smooth transitions of heats are vital for the success of the event and will require all swimmers cooperation throughout the day. Please be prepared when your heat is due to swim.
