Loading and Unloading
Loading and unloading operations have a dramatic effect on stability. For example, when a heavy load is lifted clear of the water it has the same effect on the vessel’s centre of gravity as if the weight were actually at the head of the boom. The vessel will also heel. All such operations should proceed with extreme caution.
Heavy icing, especially when it accumulates, will seriously affect stability. In severe conditions it is very dangerous. If icing occurs, all fishing gear should be recovered and secured as low as possible on deck. Speed should be reduced, and the vessel turned downwind if possible. If crew are sent on deck, they should have safety lines attached. If possible, ice should be removed from upper structures.
