What element is NOT typically included in pre-departure checks?

The element that is not typically included in pre-departure checks is passenger heights. Pre-departure checks are focused on items that directly affect the safety and functionality of the vessel as well as the readiness for the trip. This includes ensuring that safety equipment is on board and properly functioning, assessing weather conditions for safe navigation, and checking fuel levels to ensure the vessel can complete its journey without running out.

While it may be important to know the height of passengers for things like safety gear fitting or stability calculations in specialized cases, it is not a standard check for most vessels. The other options are critical components of ensuring safe operation. Safety equipment ensures that in case of an emergency, the necessary tools and gear are available. Weather conditions are vital for planning the route and avoiding dangerous conditions on the water. Fuel levels directly impact the ability of the vessel to travel the intended distance. Therefore, passenger heights are not considered a necessary part of the pre-departure checklist.
