For the purposes of sanctioning and documenting swims across the Monterey Bay, the preferred route is harbor to harbor:
North End (Santa Cruz) - Harbor or Seabright Beaches (adjacent to SC Harbor)
South End (Monterey) - San Carlos Beach (adjacent to the Monterey Harbor)
This course is 25 miles / 40.23 Kilometers
A "bay swim" must have clearly defined boundaries for starting and ending a swim. Swimming from Santa Cruz to Marina, for example, would NOT qualify as a Monterey Bay crossing.
