Contact the owner of the RIB. GPS receivers typically store position every few seconds into a circular track buffer with about
4-16 thousand entries. The entries in the track buffer are time stamped. The can be downloaded to a PC with appropriate SW and you
can figure out where the boat was when the gear was dropped.

I did exactly this just a couple of weeks ago. Linda lost a dive
light getting out of her gear and we didn't discover it was missing
until we got home. I analyzed the GPS track, figured out where the
boat was at the end of the dive, dropped the hook 30' upwind of
the position, and there it was right under the anchor line and
30' from the hook.
