That's my point.
Rental operators are required to go through a safety training program with all renters. Rentals are often half an hour to an hour. That's all a person wants to spend with them. I'm hearing this from rental operators where I come from. It would end their business if every person who was interested in renting needed to have a personal pleasure craft operator card.
I believe this has been looked at. The current situation, where rental operators must provide training on site on the exact vessel a person is going to be operating, has been far more effective than a PCOC.
