Question 21Navigation General

The correct answer is D) 1:35,000. Harbor charts typically have a scale of 1:25,000 to 1:50,000, with 1:35,000 being a common scale used. This scale provides enough detail for navigating in harbors, ports, and other confined waterways. Option B (not more than 1:25,000) is too large of a scale, while options A (not less than 1:500,000) and C (1:150,000) are too small of a scale to be considered a typical harbor chart scale.
