Coast Guard Investigative Service

MSIB 1-23

Reporting Sexual Misconduct on U.S. Vessels

***See attachment for full text***

Sexual misconduct that occurs onboard U.S. flagged vessels harms mariners, interrupts safe operations, and often leads to accidents, lost careers, and a lifetime of trauma for the survivors who endure the abuse. The Coast Guard is committed to investigating and pursuing appropriate enforcement actions for all reports of sexual misconduct on U.S. flagged vessels. This MSIB supersedes the Assistant Commandant for Prevention Policy’s MSIB 11-21 “Reporting Sexual Assaults on U.S. Vessels” issued on December 16, 2021.
