Worth the money to buy. ### 5/5 — Outstanding reference guide! *2018-01-17, version 4.1.0* I’ve had this little book for about 15 years now, and while it may have been updated to reflect current technology, the basics will pretty much always be there. I’ve done a fair bit of offshore sailing and (you may think this weird), I read various sections of the book regularly as a way to pass time. E.g, the section on clouds - I can never remember the names of the various clouds - we’ll, there they are! I can’t speak highly enough or this reference. Thanks to the author!! I just bought this on-line version for my iPhone. There it is on the screen now. Also, if you’ve never seen or bought Grog’s knots - do so. Fabulously easy to fathom how to tie knots. Well done! ### 4/5 — Useful for Boaters *2017-08-07, version 4.1.0* Still exploring but I like what I've seen so far. ### 5/5 — Great App *2017-07-24, version 4.1.0* This has an incredible amount of information that any boater whether beginner or advanced.
