On which types of vessels is carrying GMDSS equipment mandatory?

Carrying GMDSS (Global Maritime Distress and Safety System) equipment is mandatory on specific types of vessels to ensure maritime safety and effective communication in emergencies. The correct answer highlights that passenger ships engaged in international voyages and non-pleasure craft over 8 meters are required to have GMDSS equipment.

This requirement is based on the understanding that passenger ships, due to the number of people on board and their operational nature, must be equipped with reliable communication systems to handle emergencies effectively. Additionally, non-pleasure craft over 8 meters are also included in this category to ensure that larger vessels engaged in commercial operations meet safety standards, considering their increased operational risks and responsibilities.

Smaller vessels, such as personal yachts and recreational boats, may not always be required to have such equipment depending on their size and use; thus, they do not fall under the mandatory requirement as stated for GMDSS equipment. Similarly, while large cargo ships may also require GMDSS, they are not the only category where this is applicable, as the focus of the question encompasses a broader range of specified vessels. Therefore, the correct choice effectively identifies the vessels that must comply with GMDSS regulations to enhance safety measures at sea.
