A coastal navigator plots a course in an area with a known tidal stream setting 090° at 2.0 knots. If the vessel steers True Course 000° at an engine speed of 8.0 knots for 1 hour, what is the vessel's resulting Course Over Ground (Rumbo efectivo - Ref) and Speed Over Ground (Velocidad efectiva - Vef)?

1. Ref ≈ 014°, Vef ≈ 8.2 knots
2. Ref ≈ 090°, Vef ≈ 10.0 knots
3. Ref ≈ 346°, Vef ≈ 6.0 knots
4. Ref ≈ 045°, Vef ≈ 16.0 knots
