Would be good to add TVMDC calculator

This app is what every boater needs, terrific!

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

Many more tools than advertised!

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.

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.

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

Awesome ! Please do one for windows phone !
