FAQ + Best Practices for MSF Documented Swims
We've gotten a few questions lately about whether single-witness swims will pass muster to be documented by the Marathon Swimmers Federation. I'm pasting in below answers to these questions as drafted by the rules co-authors--me, Donal Buckley, Evan Morrison and Andrew Malinak)
Q: Can my swim be crewed, observed/documented, and piloted/navigated all by a single person?
A: No. Although we are sympathetic with the manpower challenges and expense of marathon swimming, MSF Documented Swims require at least two people to assist the swimmer to cover the three critical roles involved with supporting the swimmer. One role is observer, the second is navigator/pilot/kayaker who charts the course, and the third is the crew who feeds the swimmer. How these roles are assigned across a two-witness event should be based on safety considerations and common sense. If a third person is available, that’s considered ideal because then each role can be given primary attention by the individual performing it.
The reason these roles are split across multiple individuals is because each requires specific skills and attention. It would be unsafe (and impractical) for the pilot or kayaker to be required to also observe a swim. In some instances, the kayaker charts the course and feeds the swimmer simultaneously, but they cannot also act as the official observer, not only for safety reasons, but also because of the potential for a conflict of interest. If the official observer - who is intended to be an independent, impartial witness to the swim - is also invested in feeding and guiding the swimmer, their objective independence may falter.
Generally speaking, the more witnesses there are to a swim, the greater the credibility of the claims.
Q: Can I use a video camera as my independent observer/documenter of my swim?
A: No. Although digital media technology improves every day, we believe it will never be able to completely replace an experienced observer. This independent witness can comment on potential infractions and issues that a camera may not show. Also, GPS devices and video cameras are notorious for failing partway through a swim, and because of this unreliability, raw footage of a swim is not considered authoritative enough to substantiate claims submitted for MSF Documented Swim status as a standalone source. Video is a wonderful secondary substantiation of a swim when submitted with a thorough observer’s report from an objective, impartial witness to the swim.
