ENG Blue eye is an application designed to systematically record data on marine organisms and sea pollution with the aim of increasing knowledge of the sea and its effective protection. Everyone who spends time in nature, on land or at the sea, walking, hiking, diving, sailing, or swimming, can signal an unusual event that endangers the current state of the environment. When encountering an unknown, interesting or potentially dangerous species, you can find out what they are, whether a plant or animal is protected, rare or dangerous. By logging in to the Blue Eye application and filling in your data, you will receive, as soon as possible, information about your observation of nature, an unusual event, or recorded species on the seashore, in or on the surface of the sea. At the same time, with the data recorded, experts get useful information that serves them in further research and in properly informing the public on the recorded species. By delivering photos and information, a person can actively participate and assist in scientific research (Citizen Science) thus achieving a better insight in the movement of a given organism and more effective measures for the protection of the Adriatic Sea. The purpose of the application is mutual informing and education of the public, as well as the effective operation of experts and services in charge in solving possible problems related to the protection of the Adriatic Sea. Mutual information transmission creates a more complete picture of the state of biodiversity and the movements of possible dangerous species.

The world’s most recognized database for production sailboat specifications. This is the must-have app for those looking to purchase a sailboat as well as for DIYers, sailmakers, yacht brokers, marinas, riggers, and all other marine professionals. Unlike our website, the app allows access to our database without the need for an internet connection. After downloading, you can experience the full app functionality for the first 2 hours. After that, continue on with the free basic version or subscribe to keep full access. This costs as little as a good coffee (for a yearly subscription, our cheapest option) and supports us adding more useful features and extend the database. The current features include: • Scrollable list containing over 9,200 sailboat models. • Side-by-side sailboat model compare. • Scrollable lists with all designers, builders, and associations. • The scrollable lists have an alphabetic index for quick access. • Each list has a name search bar which updates the list as you type. • Ability to select sailboats, designers, builders, and associations as your favorite. • Toggle button to quickly switch between showing all or only your favorites. • Ability to add your personal remarks for each sailboat model. • Favorites and remarks are shared between all your devices using Apple iCloud. • Refined search by LOA, LWL, Hull type, Keel type, Displacement, Beam, Draft, Rig type, Years Built and all our Ratios. • Ability to sort the refined search results on any of the search parameters. • Settings to personalize displayed units and other features. As you scroll through the sailboat list and look at sailboat and designer details, the corresponding images are downloaded via internet. Once an image has been downloaded it is stored on your device; the maximum storage used is about 500MB.
