The OPV trend. This's just my personal OPV's opinion, but I do tend to think OPV's should belong to Coast Guard and not Navy.
Coast Guard is in reality already become quasi Navy anyway. Still the duty of coast guard seems more appropriate for function of OPV's handle by them and not Navy.
I know not all nation has capabilities to build decent Coast Guard, and some who has seems decided not to build it due to organization issue, don't want to differentiate maritime security jurisdiction, and also Manning issue.
Again it's just my personal opinion, perhaps because I tend to differentiate the Navy to focus on defense while other maritime security and SAR function done by Coast Guard.
