High number of stowaway cases. Each successful boarding of a stowaway represents a failure in ships security; it can bring danger to the ship’s crew and can result in the death or injury of the stowaway(s) if they enter a dangerous location on the ship.  

As well as the safety aspect, stowaway incidents are expensive and often slow to resolve, resulting in substantial costs and disruption for the Shipowners affected. Evidence suggests that the cost of resolving each stowaway claim is also increasing, with the cost to the Club in the first quarter, approaching the same as last year’s total. Also, the stowaways are often coming in larger groups, increasing the complexity of confining them if found and adding to the cost of repatriation 

These incidents can often result in substantial disruption to ships operations and may even result in punishment for the ship affected.
