NaAVIC, is a free and downloadable Electronic Chart System app specifically developed for boats of all sizes looking for safe and reliable professional navigation functionality on mobile devices and/or laptops. The app offers a range of features to make navigation easy and reliable, delivered through a clear and intuitive interface designed specifically for navigating at sea. The capabilities cover the range of essential features needed to maintain safety and situational awareness. Separate processes for download and update of the electronic chart data is not required because data is streamed in real-time from a cloud based open source database. The data is supplied to NaAVIC from Nautilus Cloud, a cloud based infrastructure designed for Marine Data, Solutions and Services for Government Organizations, Commercial Industry and Consumers. Nautilus Cloud is a “cloud native” approach and leverages high quality, open source components as its base technology. It uses open standards throughout to build a low-cost system which is flexible and has a much greater degree of interoperability with pre-existing components. A key feature of the Nautilus Cloud platform is the expansion of data holdings into a much wider family of related geospatial data products including the S-100 framework, harmonized metadata, raster and real-time sources. In essence, NaAVIC can operate on real-time and up-to-date information from charting agencies without a separate updating process. This enables the integration of real-time tides, weather, currents and other oceanographic information.

Although SOLAS still requires nautical paper charts on pleasure crafts, more and more sailors prefer navigating digitally. What are the impacts on their spatial abilities? We conducted a field experiment at the Baltic coast and two simulator experiments with altogether 40 sailors. Participants plotted and/or piloted routes either in the classic manner on paper charts or digitally on an ECS. We assessed the situation awareness, the cognitive map, and (for the simulator only) the wayfinding with and without the navigation media. We found that digital navigation significantly impaired the cognitive map. Its impact on situation awareness, however, depended on previous navigation habits: Only sailors who used their paper charts regularly and actively benefitted from the ECS. We concluded that ECS navigation with its high level of automation lastingly alters spatial perception at sea and impairs orienting. With the vulnerable electricity supply on sailboats, this is a safety issue for shipping.

In the article the author attempts to isolate, clarify, systematize, and classify various types and kinds of electronic navigational charts used in electronic chart systems, their specificity, operational status, significance and role they play. In particular he tries to promote internationally standardized vector charts ENCs (Electronic Navigational Charts), and raster charts RNCs (Raster Navigational Chart), as well as military Digital Nautical Charts (DNCs), High Density Bathymetric ENCs (bENCs), Port ENCs (PENCs), Inland ENCs (I-ENCs), Three Dimensional Digital Nautical Charts (3DNCs) and others. He presents general classification of electronic charts data bases taking into account the following criteria: spatial dimension, data types (data format), official status, international standards, consistency, level of detail of bathymetry, data confidence (reliability, accuracy), navigational purpose, and indirectly also the compilation scale of the chart, size and arrangement of cells.

An Electronic Chart Display and Information System (ECDIS) is a highly advanced and powerful navigational aid, specifically designed for enhancing safety at sea. With the growing adoption of ECDIS (ECS) there is an increasing number of Officers who need to be trained in its use. Given the flexibility of the labor market, it is highly likely that Officers may arrive onboard a ship without experience or training. To adequately train responsible personnel, Transas has developed specialized ECDIS Operator Training Equipment. In the papers Jochen Rudolph focuses on the requirements set out by existing IMO regulations for ECDIS operators and outlines the distinctive features of the ECDIS Operator Training.
