What type of information do information (non-lateral) markers typically provide?

Information markers, also known as non-lateral markers, are used specifically to convey non-regulatory information to boaters. They provide valuable details that can assist in safe and informed navigation on waterways. This includes information about nearby services, such as fuel, food, and lodging, as well as distances to certain locations. Such markers help boaters plan their trips more effectively and understand what resources are available in the area they are navigating.

In contrast, the other options focus on aspects that non-lateral markers do not typically cover. Detailed maps of underwater features are generally not provided by these markers; such information is usually available in nautical charts. Emergency contact information could be found in specific safety guidelines or signage rather than on non-lateral markers, while safe navigation routes are generally governed by lateral markers that delineate navigable waters. Thus, the primary function of non-lateral markers is to relay essential information that enhances a boater's experience and helps them make informed decisions while on the water.
