I'm in Abaco right now and I will say that the level of competency demonstrated by bareboat charterers in BVI would be entirely inadequate here. Cruising here really underscores that there is very little valid reason to run aground in the BVI, despite that being a regular occurrence. There is no comparison.
As an owner, I can't say that I'm unhappy about it and I wish they would institute this requirement in the BVI, it might give some of the least qualified some pause.
That said, the IPC is very easy to get if you have the ASA courses, I just got mine in anticipation of going to Croatia next year.
