Thank you for supporting a swimmer or relay team for this year’s Boston Light Swim on Friday, August 9, 2024!

Pre-Race Briefing and Dinner

You are invited to attend one of the live, virtual, pre-race safety meetings to be held in late-July and the first week of August 2024. Log in information will be posted here closer to the day and sent directly to you via email and SMS message. It’s not mandatory for you to attend the safety meeting live, but we do ask that you watch the recording at minimum.

In addition to the safety meeting, you are invited to our pre-race dinner at Boston Harbor Yacht Club the evening before the swim. This will allow you a chance to meet your swimmer, other swimmers and boaters, as well as hear a little about the race history (dating back to 1907!), and have. a chance to again review the schedule of events, safety protocol, and ask any last minute questions you may have.

Race Day: Meet Your Swimmer at BHYC!

Meet your swimmer at the dock at BHYC no later than 7:45 a.m. to motor out to the lighthouse for the start of the race. (Allow more time if you expect the ride out to the light to take longer than 45 minutes.) The race begins promptly at 8:45 a.m. We know it’s early, but we’re catching the tide, and there will be less recreational boat traffic on the water early in the morning.

Flags

Your swimmer will receive a packet of flags upon check-in the morning of the race. They will hand these to you when they board your boat. Please fly these banners and flags from your boat for the duration of the swim. They help mark your boat as part of the race and are an important safety aid to other boaters on the course. At the conclusion of the swim, please give the flags to the crew member(s) disembarking at the BHYC. They will bring the flags back to the finish line and the race directors. We need the flags back to keep race costs down!

RD’s Cell Phone

Please note, Race Director Mina Elnaccash is the primary contact for this event. You may call her on 617-216-2274 with questions or concerns. If your swimmer pulls out before the finish, please contact Mina via call or text message to let her know that you have removed your swimmer from the water.

Swimmers Who Withdraw Early

If your swimmer is unable to complete the race, they will need a ride back to the BHYC. In the event of a medical or safety emergency, please contact the race director or the USCG. Regardless of reason, we need to know as soon as a swimmer pulls out so that all participants are accounted for, in or out of the water.

Radio Communications

Please monitor channel 72 for race info and use channel 16 to reach the Coast Guard in the event of an emergency.

Safety Boats

  • There will be three event safety boats on the course. One will be in the front, one will be in the rear, and one will be patrolling the middle of the pack of swimmers.

  • The U.S. Coast Guard will be present and they have the authority to cancel the event for any reason.

Course

See a course map and detailed description here. This swim is unique in that the islands are your markers. Boats will line up in a north-south line extending due south from the Boston Light. Please try to hold this line as best you can so that swimmers have a fair starting point. (See image below)

  1. Georges Island: Stay left of the island, 200 yards or more offshore. Watch for ferries coming in to dock.

  2. Rainsford Island: Stay to the right of the island.

  3. Long Island: Head toward the water tower. Watch out for outgoing boat traffic around the 4-mile mark. Keep Long Island on your right and skirt along the southern coast of the island until you reach where the Long Island Bridge used to stand (4.5-mile mark). IMPORTANT: Head for one of the middle stanchions of where the bridge used to be.

  4. Moon Island will be on your left as you clear the site of the old bridge.

  5. Keep moving straight ahead between Thompson and Spectacle Islands. Thompson will be on your left, Spectacle on the right. Aim a little closer to Thompson, but be aware that for slower swimmers, there could be a slight cross-current from right to left that can push them toward Moon Island. Try to keep on track for Thompson Island.

  6. After rounding Thompson Island (6-mile mark) you have two miles to go. The Boston skyline will be in sight. You’ll see one particularly tall building in the skyline, so head toward that building. As you get closer (within 1 mile of the finish) you’ll begin to be able to see the white handball courts at the L Street bathhouse.

  7. FINISH: M Street beach within the fence of the Curley Community Center. It’s the first walled off section after the public beach at M Street. There will be two, large, orange markers out in front of the walls, a large FINISH banner, tents, people, and an orange mesh-fenced finish chute. Once your swimmer finishes, you can motor back to the BHYC dock to drop off the crew and their bags. The crew will take the boat flags from you and return them to the finishline where they will meet their swimmers. Boaters, if you have a place to safely dock your boat, please feel free to come join us for the afterparty on the beach. (The BHYC is only accessible for dropping off swimmers and crew, not for docking.)

Rules

  • We have a strict 5.5-hour limit on the course. Boaters, if your swimmer is still in the water at 2:15 p.m., they must enter your escort boat and be dropped off at the BHYC.

  • Swimmers may not touch escort boats or crew members during the swim (unless it’s a relay). Rules are all spelled out here.

  • Swimmers must wear the numbered, fluorescent caps we provide while in the water.

  • Escort boats must display their swimmers’ number and the red/white diver down flag. (Please return these flags at the end of your swim.)

  • No wetsuits are allowed.

  • Kayaks may only be used as secondary support; in the event of an emergency or event cancellation, the accompanying escort boat must be able to accommodate the kayak and kayaker for the ride back to shore.

Event Cancellation

The race will proceed rain or shine. We will only cancel the event if the Coast Guard deems conditions too dangerous or there’s thunder/lightning or thick fog that reduces visibility to unsafe distances. If we need to cancel, we’ll notify you via email as soon as possible. Please make sure the race director has a current, accurate email address on file for you.
