I have tried to complete the sevensurveyor project and developed one simple software for draft survey calculation named 7S DraftSurvey.
This software is made for automatic draft survey calculation such as; quartermean draft, trim, fore and aft draft corrections, Displacement, TPC, LCF, MTC, 1st & 2nd trim corrections, density correction, and deductibles. The software could be used to determine the total cargo loading/unloading on the shipboard.
It is very simple and helpful to cut down the time for draft survey calculation. What you have to do is just inserting some data in the initial draft survey and get easy calculating for any intermediate and final draft survey with insert the reading draft, density, and sum of deductibles only. This software designed to handle the ship with reading draft marks up to 27.00 Meters.
