About this app

This App enables any Master , Mates and Surveyors to conduct an instant Draft Survey and ascertain the Cargo on Board. This App is not limited to any Ship Size. Draft Surveyors can work on a particular range of drafts , they do not need to use the complete hydrostatic table loaded.
There is no limits to number of ships or draft observations.
The accuracy is based on the Hydrostatic Table . The closer interval the more accurate the result. The App provide this factor. The minimum is 1 cm interval.
For an upright ship a total number of 6 data is required from the Hydrostatic tables.
If a particular range is not found the App will provide ad hoc inclusion.
A complete working version video is available to users on YouTube.
WHAT IS A DRAFT SURVEY
A Draft Survey is a method used on board ships to determine the weight of cargo loaded or discharged by measuring the vessel’s drafts before and after loading. This process involves reading the draft marks on the ship’s hull, correcting for factors such as trim, water density, and ballast, and using hydrostatic tables to calculate the displacement. The difference in displacement before and after cargo operations gives the cargo weight. Draft surveys are commonly used for bulk cargoes like coal, grain, and ore, ensuring accurate measurement for commercial and regulatory purposes.
