A great reference and calculator.

Just got it. Love it already. Love the leeway calculator.

Very Handy

Many more tools than advertised!

Why more info then I thought.

Had it just for a short while now, no crashes. Opens every time and has way, way more info then I ever thought it would have.


One significant issue with propeller sizing: it fails to take gear ratio into account so the result is that the recommended propeller size is much larger than necessary.

Great app!

This was a great app before the newest version, but it is now outstanding! This is the first review I have written for any app, and I have several hundred, many of which I've deleted after not finding them useful or them being the best of a category. This newest version of the app just does so much, and the UI is beautiful and elegant.


Very good basic tool for general sailing. Unfortunately it does not have yet a True Wind Calc which would be very useful for sailing in any environment. Have to say the Air Pilot Calc has it.

Awesome application

This has everything that a boater will ever need. Excellent app and well worth the money.

C . N . S .

Awesome ! Please do one for windows phone !

The ultimate little boating app!

A remarkably useful app! Very informative and practical! Love the interface and page layouts. Keep up the good work!

Everything it claims to be

This app is all it claims to be and more! Exceptionally great quick reference program. Why try to remember formulas and have notes jotted all over when this app remembers everything you'll need for you? For only $2 I can't imagine any boater not wanting this great reference on hand!


Perfect (nearly)


Tremenda aplicaciĆ³n !!!!!

Very good


No bad

Not bad app for boating. It would be nice to be able to change some of the consumption rates in the fuel flow calcs. I was looking for a vmg calc. It does not have one. A vmg calc would be a nice addition.
