The story says "Titan RHIB, unexpectedly detached from the trailer hitch while being towed on Highway 19". No clue what system they use to attach the trailer to the tow vehicle, but, i know one thing, they all have "TWO" safety chains to allow the tow vehicle to stay attached to the trailer in the event the hitch system fails. It can be ugly but it'll stop the trailer/boat from taking off on its own. Maybe the chains broke but that seems unlikely. This article in the paper doesn't pass the smell test. Doubt we'll ever know what happened. It's interesting because Campbell River is the only place I have ever been stopped by the RCMP to check my trailer straps. Back in 2017 or so they were on a rage there because of a couple of serious boat/trailer accidents.
