Tymor Marine's breakthrough DRFT MRKS technology measures a vessel's draft from a 30-second, 1080p HD video. It is an industry-leading AI/Deep Learning technology developed to improve the traditional draft reading process. DRFT MRKS aims to allow anyone to read draft marks with the same skill and accuracy as an experienced mariner.
