70% to pass

Entering from seaward, triangular-shaped daymarks are used to mark _______________.

A special purpose areas
B the starboard side of the channel
C an obstruction where the preferred channel is to starboard
D the centerline of the channel
AI Explanation

The correct answer is B) the starboard side of the channel. Triangular-shaped daymarks with their points up are used to mark the starboard (right) side of a navigable channel when entering from seaward. This is a standard navigation rule to help boaters safely navigate through marked channels. The other answer choices are incorrect because they do not correctly identify the purpose of the triangular daymarks.
