Sources disagree
The crossing established the first successful Channel swim by a woman and surpassed the previous men’s time.
CSA and the specific museum record give 14h39m; historical durations and clock times conflict.

How this record was checked
CSA record 2236 identifies Ederle, United States, solo France to England and 14h39. CS&PF historical entry 442807 names the CSA as ratifier and gives the same elapsed time. The Dover swim entry records independent observation followed by CSA recognition on 16 August 1928. These sources establish the crossing and its registered duration. Accounts disagree on the clocks.

Supports · Contemporary account of Ederle’s crossing, Kingsdown landing, Alsace escort and a reported 14h 31m duration.
Limitations · A contemporary magazine narrative, not a timing log. Its duration disagrees with CSA’s 14h 39m and other published times.
Dover Museum: Records and Firsts
Checked 2026-10-31
Supports · Identifies Ederle’s and Abertondo’s pioneering swims, but prints different elapsed times.
Limitations · Retrospective summary prints 14h 33m for Ederle and 43h 05m for Abertondo. Those figures are not adopted over the individual CSA records.

Supports · Contemporary named report gives 6 August departure 07:09 and arrival 21:40 at Kingsdown, with 14h31m elapsed.
Limitations · Original newspaper scan visually inspected through University of Oregon Libraries. These clocks and duration conflict with the museum record; this is press reporting, not an original timing log.
