What occurs when entering from seaward regarding a starboard side daymark?

When entering from seaward, a starboard side daymark is designed to assist mariners in navigation by indicating safe channels. The important aspect of such daymarks is that they are typically colored green, with even numbers assigned to them. This numbering system, where starboard side aids have even numbers, helps to provide orientation and assist with the understanding of the channel layout, enhancing the safety of navigation.

The relationship between the color (green) and the numbering system (even numbers) is also established in the lateral system of buoyage. This adherence to uniformity in markings and numbering is crucial for ensuring that vessels can easily recognize navigational hazards and safe passage routes. The rest of the provided options do not accurately describe the characteristics of a starboard side daymark when approaching from the sea, making the even-numbering system the correct indicator.
