The capability is very real. And they don't have to sink the ship, just one Shahed drone exploding on the deck and injuring/killing a sailor is deterrence enough.

The Shahed drone is a 'set it and forget it' device where you program a stationary target and launch it. It would not work well for moving targets, like ships.

Russia has been modifying Shahed drones for quite a while. May be they've shared back or Iran got creative on their own

The Iranians are quite handy at modifying their drones....
