It's also the ideal tool for yachting charter companies, rental management agencies, boatyards and marine mechanics.

Whether you take to the water for coastal cruising, leisure fishing, competing in regattas, powerboating or even setting sail for ocean passages, your boat needs to be prepared and checked before leaving port. This boating app can even be used for inland waterways canal boats or leisure craft! Thousands of boaters already track the upkeep of their equipment: engine, sails, inflatable, liferaft, lifejackets, fire extinguishers, stove, batteries, tender, rigging, windlass, outboard, electronics, VHF radio and NAVTEX receiver… You too can monitor it all in one place. Ready4Sea is just as essential on board as a marine weather or tide prediction app, an almanac, a pilot guide or an anchor alarm. It’s the logical next step after getting your boater’s license and buying a boat. — Ready4Sea was unveiled at the last Paris Boat Show, and has since been featured in numerous nautical and yachting magazines such as Multihulls World.
