Field notes
The stated input is a 3D vessel model plus a profile drawing; listed outputs include a deadweight-survey worksheet, wind-heel check, and collar-puncture cases. The page anchors its method to 46 CFR provisions, Coast Guard Marine Safety Center notes and procedures, and ASTM F1321, while saying updates follow revised guidance. It also offers help if owners lack accurate drawings, though the excerpt does not explain the review or delivery process.
