C Class Ferries
From Wikipedia:
The C-Class ferries (also known as Cowichan Class) are a class of five double-ended roll-on/roll-off ferries operated by BC Ferries in the Strait of Georgia in British Columbia, all
constructed between 1976 and 1981. When the vessels were first built, they were the largest ships of their kind in the world. The C-Class ferries are 139.29 m (457.0 ft)
long, with a car capacity of 362, and a crew and passenger capacity of 1500 persons. Each vessel's two MaK 12M551AK engines produce 11,860 HP, which provides a service
speed of 22 knots.
The first two C-class ferries were the
Queen of Coquitlam and the Queen of Cowichan, constructed in 1976. The Queen of Oak Bay and Queen of Surrey were built in 1981.
There are some minor modifications to the design of these two ships compared to the earlier C-Class ships.

The
Queen of Alberni was also constructed in 1976 along with the first two C-class vessels. Although this ferry is considered to be a C-Class vessel, it is significantly different in
layout. It was originally designed to carry only overheight (truck) traffic. In 1984, an upper car deck was installed for 150 non-overheight vehicles. This ferry has a
capacity of 292 cars and 800 passengers and crew, and has a maximum service speed of 19 knots. She underwent a refit in 1999.

The
Queens of Coquitlam, Cowichan, Oak Bay, and Surrey each received extensive upgrades in 2003, 2004, 2005, and 2006 respectively. From engine work to major
modifications and improvements, the vessels were refitted to provide an additional 20 years of service.
