Nothing, it seems is paper-only these days. (Then there's those, like Sail-World, who are digital only). The latest nautical aid, the Sea Safety Guide from the Royal National Lifesaving Institution (RNLI), has gone digital and interactive as well.
Sea Safety interactive guide from the RNLI
The information too, is new and updated, and has just been launched this week.
The Complete Guide is the RNLI's handbook of essential information and is a 'must have' for all those who go to sea.
Its new, interactive format means that sea safety is available on mobiles, tablets and laptops and at the tip of boaters' fingertips.
Tony Wafer, RNLI Coastal Safety Manager, said: 'We recommend that all those who enjoy the water follow some simple guidelines: get some training, tell someone where you're going, check the weather and tides, wear a lifejacket, check your safety equipment and carry spares, and carry a means of calling for help.
'The Complete Guide gives more in-depth advice on how to follow these principles and stay safe on the water. It'll cover everything from how to plan your time on the water, what safety equipment to take and how to use it, and what to do in an emergency.'
It's easy to use too, just the ticket for the digitally literate cruising sailor.
