It is a fact that not only ships, but also seafarers and passengers vanish without a trace at sea, be it in the past or in present times. Several examples for this phenomenon are given. A scheme of the ship conditions found after discovering that single persons or even whole crews had disappeared from board is provided as an orientation, before describing in detail the more than 18 reasons for vanishing from ships for good, giving examples where appropriate. These reasons are in their majority logical, but strange and bizarre reasons also exist. Causes may e.g. be the sea state, crimes, suicide, alcohol, piracy. A chapter concerning passengers lost from large modem cruise ships, especially in the Caribbean, follows. Finally, suggestions are made, for instance psychological aptitude tests, as regards how to maybe help decrease the number of disappearing persons, especially young seafarers, from aboard ships on the high seas.

This literature review aims to provide an analysis of the current trends in at-sea medical evacuations (medevacs), with the objective of providing insights to decision-makers to improve patient outcomes. Sixteen sources spanning diverse research methodologies were employed for data collection. The findings point to medical disease processes outweighing trauma and psychiatric conditions as the primary justifications for medical evacuations in the international maritime community.

Whole-genome analyses suggested a single or limited number of viral introductions consistent with the epidemiologic course of infections. Although some precautionary measures were taken, no social distancing was exercised, and air circulation and ventilation were suboptimal.

Despite millions of seafarers and passengers staying on ships each year, few studies have been conducted on the indoor air quality inside ship hulls. In this study, we investigated the levels and size distribution of indoor particulate matter during two cruises of the research vessel "Xuelong" from Shanghai to Antarctica. The results showed that the particle size less than 2.

Due to a ship's extreme motion, there is a risk of injuries and accidents as people may become unbalanced and be injured or fall from the ship. Thus, individuals must adjust their movements when walking in an unstable environment to avoid falling or losing balance. A person's ability to control their center of mass (COM) during lateral motion is critical to maintaining balance when walking.
