Sorry for not having read every post in this thread, and I'm not well read on SSi's Standards and Protocols, but it seems to me that the instructor violated some very important standards relating to OW students and supervision. I'm a PADI instructor. It's very clear in PADI's S and P, that an instructor can NEVER leave an OW student unattended... on the surface, or underwater. SSI instructors care to chime in on that? Is there an SSI method for reporting that?
