A little checking has shown me that the Lifesling2 does not meet the
requirements of the USCG for a 24" ring buoy to be carried on a vessel
which transports passengers for hire. It does appear that the new
Lifesling3 does meet these requirements, though.

It would be advisable for all to do the appropriate research on your
own, as I am not a maritime attorney and hold no other special
qualifications in this field.
