@Infoseepage @SoftwareTheron @WellsiteGeo The problem is that drug smugglers also know about using sail boats, so there's already a massive infrastructure of coast guard patrols detecting, tracking, and intercepting them.
But they have a zero percent success rate in intercepting submarine narco subs. Zero percent.
And Iran has midget subs that are more sophisticated than the relative junk drug smugglers use.
