Could there be a network or association of clubs that do this that's somehow tied into US Sailing, with some liability mitigation and/or certification process?

My club, CSYC on Lk St. Clair, now has a club Wave and Tiger and looking to get something in between (H16 or T2 or Nacra500 or...). As someone who travels frequently for business, it would be nice to have some reciprocity arrangement set up for boat use/rental at other locations.

FWIW, have not even mentioned such an idea to CSYC officers, but having a 3rd party help facilitate and reduce both risk and cost would certainly help it get off the ground.
