Since the mid 1990′s the United States Coast Guard has published several notices concerning proposed regulations involving propeller guards & other propeller safety devices, and requested public input on those proposals. While much of the focus has been on propeller guards, other propeller safety devices have also been discussed. Among them are swim ladder interlock switches, backup alarms, mirrors, swim gate switches, kill switches, virtual kill switches, starter delays (beeps for a few seconds before starts), and rear view cameras.

A few notices have only requested comments, however, most of them refer to a proposed rule. When notices of a proposed rule are first published, they are typically marked as a “Notice of Proposed Rulemaking” (NPRM) or as an “Advanced Notice of Proposed Rulemaking” (ANPRM).
The process appears to have been less defined prior to 1998. The Coast Guard was using its own set of docket numbers and reused one of them several times as a rental boat propeller safety project continued to evolve. USCG opened and closed public comment periods numerous times, renamed the proposal a few times, then finally renumbered the proposal under the new docket system in order to archive the records.
In this post we bring all those notices together and post them as a timeline. Read More→
