MOWSA exists to help swimmers challenge themselves and reach big goals in Massachusetts' waters.

Want to do one of the established solo marathon swims we offer or another solo marathon swim in Massachusetts? Start by reading our rules and shark protocol.

If you’re still interested, contact the recommended pilot for your course for availability. (Swimmers must arrange boating support directly with the pilot and pilot fees are separate from MOWSA sanctioning fees. MOWSA will supply an observer and organize necessary Coast Guard and other permits from regulatory agencies.)

Finally, fill out an Application for Sanction of a MOWSA Marathon Swim and contact us to get the ball rolling. 

We look forward to helping you achieve your goal!
