NNNOOOTTTEEESSS TTTOOO TTTHHHEEE MMMAAASSSTTTEEERRR (1.) A copy of this stability booklet must be stowed on board the vessel at all times in a position where it is easily accessible for reference. (2.) The conditions of loading included in this booklet are intended to represent typical service requirements but different arrangements are allowable provided the effect of such loading on the vessel’s stability is determined beforehand and found to be within safe limits, as explained in this booklet. (3.) All equipment, stores and deck furniture must always be effectively secured against possible shifting due to movement of the vessel. (4.) Before operating all lifesaving equipment is to be checked to ensure it is in full working order, easily accessible and in the case of automatic releases they are correctly fitted. (5.) The crew should familiarise themselves with the position and use of the safety equipment before commencing operations. (8.) The vessel has adequate margin of stability as is demonstrated by the information contained in this booklet provided all operations are carried out in accordance with the precautions stated in this section. (9.) Loading conditions in this book are based on information provided by Land and Water Services Ltd. and are incorporated in good faith.
