This ferry is a vital link for users to travel from Kuala Penyu in Sabah. This is proven by the existence of this ferry crossing the Kuala Penyu river. The ferry operates only during the day until 3 pm.
The ferry is powered by diesel engine which will pull the attached steel chain crossing the river. Just imagine what happen if the ferry's engine malfunction, then the ferry service will be disrupted. Or what happen if the engine fails in the middle of the river and just guess what can happen. I think the operator of the ferry has thought of all of the consequences and they might have been prepared.
