PURPOSE
This site is a marine navigation calculator. It provides automated solutions to some common navigation problems that mariners deal with when cruising and in pre-cruise planning. Solving these problems normally requires the use of a calculator, maneuvering board, parallel rules, drafting compass, sharp pencil and a big eraser. Although it's not intended to replace these tools, it can be used to supplement and verify traditional methods especially in cruise planning and practice or study environment.
