But it appears there are some that sometimes don't, such as these two stories of RIBs on the Thames which were recently fined for dangerous navigation:
- One was found "navigating on the wrong side of the river near Canary Wharf and caused another vessel to take avoiding action"
- Another was coming "round a bend near North Greenwich Pier and collided with a cabin cruiser which had two people on board"
I'm pretty sure the police (or maybe PLA) response and language wasn't as graphic as in the image above (actually from the Boat Race, go Kevin!), but hopefully the message was clear.
Lets be safe out there.
