Weighing %X The vessel weight is obtained during the incline experiment by observing the draft height on the side of the vessel. This method is the most practical method because it does not require taking the vessel out of the water and it is very simple to perform. This method of obtaining the weight requires calculating the volume of the shape of the hull for incremental draft heights, recording the information for future reference on a displacement curve and placing the draft gage markings on the vessel. Obtaining the vessel weight (displacement) is accomplished by measuring the specific gravity of the water the vessel is floating on using a hydrometer to obtain the water density. The volume of water displaced is obtained by observing the draft gage on the side of the vessel and by looking at the Hydrostatic Curve of the particular vessel. The vessel weight is the multiplication of the water density times the volume of water displaced. The weighing method presented in this paper is a method for obtaining the vessel weight when the Lines Plan, Hydrostatic Curves or hull shape information is not available, scales are not available, the vessel cannot be taken out of the water and placed on the scales or if it is necessary to verify the Hydrostatic Curves. Air, space and ground vehicle are weighed on scales to verify the calculated weight, it would be nice to verify the Hydrostatic Curves of a vessel. The accuracy of the result obtained using this method depends on the precautions taken and the equipment available. %B 64th Annual Conference, Annapolis, Maryland %I Society of Allied Weight Engineers, Inc. %C Annapolis, Maryland %P 15 %8 5/14/05 %G eng %U https://www.sawe.org/papers/3371/buy %9 8.
