What does SES mean in SHIPPING & SAILING

A Surface Effect Ship (SES) is a type of watercraft that utilizes an innovative design to combine the advantages of both conventional boats and hovercraft.

The main advantage of using an SES is their ability to travel over land and sea by utilizing air cushion technology. This allows for increased mobility with higher speeds than normal boats or hovercraft can reach, as well as improved stability in comparison.

Depending on the size and construction model of the SES, top speeds can range from 40-60 knots. For example, larger models such as Super-Cats have been recorded at reaching speeds in excess of 60 knots during trials.

An SES utilizes air cushion technology to achieve lift above the surface of the water by creating multiple channels of air along its hull which essentially functions like a series of hovercrafts on water - hence the hybridization between traditional boats and hovercrafts.

Yes, operators should be aware that due to its air cushion lift system, crosswinds may cause instability while operating an SES, so they should take caution while driving one in these conditions. Also it should be noted that some locations may require special licenses or permits for use depending on local laws.
