The PEI ferry Holiday Island is taking time off from its busy Caribou, NS - Wood Island, PE run for a refit at Halifax Shipyard. It arrived in Halifax October 28, and entered the Novadock floating drydock, where it has been high and dry ever since. It is now in the midst of a hull repainting.
The ship is powered by a pair of V-16 engines built by English Electric (Ruston Engine Division), each driving a Voith-Schneider propulsor, one forward and one aft. On June 21, 2013 it was announced that the engines would be replaced, and that may be part of the current work (See the large opening in the ship's hull amidships).
One of the more difficult pieces of ship's machinery to describe in words, the Voith-Schneider propeller can be seen in action on the J.M.Voith web site in a short video:
