Brilliant app
This is a vastly comprehensive reference source of the various areas of nautical knowledge. The physical book is always close at hand in the pilot house of my boat. And now to have it all in my pocket on my iPhone is a leap forward in convenience. The calculators integrated in the text make it even more useful than the printed book. Indexing and bookmarking are well executed and helpful for retrieving information you need from the abundant material in this app. Applause for the developer.
