Namely, US Coast Guard field inspectors, TPO or industry can use this online source for Subchapter M compliance requirements and guidance.

The expansion includes two new sections:

  • Appeals;
  • Alternate Compliance Options and TPO and TSMS.

In addition, a new user-friendly functionality includes links to regulatory cites, links to US Coast Guard guidance documents, and a link to a downloadable electronic version that is also printer-friendly.


However, USCG warns that some items are not applicable to every towing vessel. Thus, those using this information should understand how to determine regulatory applicability or use theInspected Towing Vessel Decision Aid (TugSafe) to generate a customized regulatory checklist for a specific vessel.

For this reason, TugSafe Central should not be used as a standalone source to determine compliance with Subchapter M.
