CoastalNav

Handy calculators for coastal navigation, at your fingertips!

Featuring:

* Nautical Slide Rule - convert speed, time, and distance by selecting any two known variables! A constant necessity for coastal navigation, our nautical slide rule is super simple and fast.

* Bearing Conversions - Instant bearing reciprocals, and bearing conversions from compass to magnetic to true (and vice versa)! We'll handle the offsets for compass deviation and magnetic variation - don't worry yourself about memorizing more salty sayings about "dull companions just adding whiskey".

* Anchor Scope - A helpful reminder for proper scope lengths, including day anchoring, overnight, and foul weather suggestions.

* Classic Conversions - Ever wonder how deep the "bottomless fathoms below" actually are? We'll convert fathoms, leagues, and Beaufort wind values into more common modern values! You'll also get WMO wind levels and can check quick descriptions of sea conditions for each Beaufort force.
