RE: Isle of Man Steam Packet Company
That sounds like Isle of Man Steam Packet Company Ships Masters where gauging whether they would have enough draft under there ships to safely get in , its not the top of the wave you have to worry about its the trough after the wave thats more worrying when there is a likelyhood of touching the bottom causing damage to the underside.

At one time until Aberdeen Harbour Entrance was deepened the same applied there , but the big difference is the cost can be equalised out by all the other users of that Harbour , it may not be the same at Douglas.
