Cape Town - Travelling by the sea makes for a wonderful holiday escape from everyday-life as we know it and for many around the word, things like ferries form a vital part of their travels.
Deciding to be a passenger on a ferry or cruise vessel in the noughties is often an amazing little holiday on its own, explains Marine Log.
Modern day passenger cruise ships are water castles and wonders - offering activities like parks, ice-skating rinks and even rock climbing in the middle of the sea.
Smaller passenger vessels, like ferries, aim to move about freely and with ease. In 2015, there was a need for environmental change in the sea travel industry, forcing passenger ship owners to evaluate their ship's designs - pushing companies to become more innovative and "incorporate greener technologies" says Marine Log.
