- ✓ Landmarks, aids to navigation, and soundingsCorrect
- C. Celestial observations, current vectors, and tidal predictions
- D. Course steered, distance run, and known starting position
Why B is correct
Bowditch Ch. 1 §103 defines piloting as navigation by reference to landmarks, aids to navigation, and soundings. Option D describes dead reckoning (Bowditch Ch. 1 §102), and option A describes electronic methods. Piloting is specifically noted as the primary method in confined waters where DR alone is insufficient.
