Her Story

The CWB Marquis was the third vessel of the Equinox class and the first of two vessels to be constructed for the Canadian Wheat Board. She was launched on July 8, 2014, and arrived in Canada on January 8, 2015. She entered service on April 2, 2015 at the start of the 2015 shipping season.

The CWB Marquis changed ownership in early 2016 after Canadian Wheat Board was sold to Global Grain Group. She was renamed G3 Marquis before sailing for the 2016 season.

The G3 Marquis is active in the Seaway grain trade.
