Check with your airline on the CO2 sylinder - United yes, AA no. We have inflatable PFDs with harness on our boat for open water passage like STT to STM. I've never worn an inflatable PFD for coastal cruising around the Virgins. I would just go with what the charter company provides.

If you really want your personal PFD why not just ship it?
