Good information
Great basic comprehensive information. Somewhat dated but a very good reference.
Don’t Waste Your Money!
Just bought this and within minutes realized I wasted my money. Found incorrect and incomplete info. Very hard to work. Referenced illustration that wasn’t there.

A Fantastic, valuable reference work. Well worth the price.
Best boating app there is!
This app is fantastic and should be in the device of every boater.
A valuable App for every boater!
This App is my go to for any question on boats from operations to conversion tables! Worth the money to buy.
Outstanding reference guide!
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!

Great App - wealth of knowledge
This is a wonderful app. Has a great depth of knowledge. I'm not sure if this is an abridged version of the hard copy book version, but this has great tables and the various in-app calculators are great. Information is accurate and well organized.
