The "International Safety Society of the Lake of Geneva" is a non profit association with over 2200 members (men & women) who work voluntarily. More than 40% of them are active today.
Its major goals are:
- To bind in a brotherliness and forethought way all the rescuers of the Lake of Geneva.
- To create a link of rescue posts in order to bring a fast and efficient assistance to people and boats in danger.
Thirty-four stations of the "SISL" are positioned around the lake, sharing a surface of 225 square miles.
Twenty-six of them are Swiss and eight French. This international organization of rescuers secures all the navigators (professionals and amateurs) on the lake of Geneva, 24 hours a day and 365 days per year.

The cruising safety fleet includes 47 units (23 patrol boats et 24 rescue boats).
