what we do best

Over 30,000 ports & terminals

We provide sea distances between any port of the world in any country, marinas, oil terminals, bunker hubs, off-shore terminals, oil-gas fields, anchorage areas and more. Our sea distances software serves over 30,000 sea/river ports & terminals worldwide. No other marine software covers such a broad and detailed water navigational network!

Detailed sea routing network

We didn’t follow the pre-calculated port distance tables root; instead, we created the most analytical & thorough sea-routing network to date, and we serve it brilliantly and on-the-fly! Our sea routing is based on many years of data analysis from navigational charts & NASA satellite ship-tracking statistics, thus bringing clarity to the maritime & shipping industry.

Fast & clever algorithms

Sea distances are not as easy to calculate as the routes on land, since the sea routing combinations are billions. Therefore, our sea routing software’s algorithms have been developed by very experienced and specialised software engineers. They are fast & they cleverly exclude certain areas based on draft and other navigational restrictions.

Fully customisable routing

Other than nautical distances between ports, Seametrix offers co-ordinate to co-ordinate routing, by allowing users to insert any co-ordinate or just click on any point on the map. Thus, you can customise your itinerary as you wish, start/end your voyage, or pass by any waypoint you want your vessel to head through.

Great Circle VS Rhumbline

Seametrix is the only sea distance calculator that offers correct and real-world Rhumbline & Great-Circle nautical mile calculation results. Each navigation method is calculated by a different server, with different data sets and algorithms, and offers highly accurate nautical mile calculation results, for either navigational method.

Over 1,000 routing points

Sea routes followed by Masters in shipping are usually the shortest. Nevertheless there are various exceptions, thus our sea network contains over 1,000 alternative routing points! Combined with the option to make any waypoint function as routing point on the fly, your route can literally be 100% tailor-made as your itinerary requires!
