noun - Swimmer's streamer (or sarashi or さらし (in Japanese) is a piece of cloth or illuminated material that is runs parallel alongside an escort boat for the benefit of a marathon swimmer during an ocean swim.

The cloth is used during daytime hours; the illuminated material is used during the nighttime hours for easier viewing. The navigational aid is hoisted from the escort boat and anchored in the water so the cloth or material runs 1-3 meters underneath the surface of the water.

Diana Nyad used a swimmer's streamer during her attempted swim from Cuba to Florida.

Advantages

The marathon swimmer can look straight down in the water at the swim streamer on every stroke in order swim straight (i.e., parallel to the escort boat). The swimmer can also conserve energy and improve their navigational course by not constantly looking up at the boat, especially during the night.

Use Around The World

The swim streamer has been used in the Tsugaru Channel and throughout Japan to protect against sharks and other marine life and is accepted as optional equipment by the Tsugaru Channel Swimming Association. It was introduced in America by Diana Nyad during her Xtreme Dream swim attempts across the Straits of Florida in 2011.
