Wind Power

 Despite advances in power generation, the wind is still popular. Today (July 31) as the offshore installation vessel Orion using its 5,000 tonne crane lifts a wind turbine base component from the heavy lift ship GPO Sapphire, there was a pleasant breeze filling the sails of a few craft in the harbour.

The harbour tour boat Silva of Halifax, a three masted schooner built in 1939 in Sweden, and an unidentified pleasure craft (sail # 51257) draw close for a look at the activity.

Meanwhile the cruise ship Caribbbean Princess called in tug assistance from the Atlantic Fir to depart from Pier 22.

 Cruise ships rarely use tugs because they have multiple thrusters and are thus highly maneuverable (and they like to avoid scuff marks on their while hulls.) However this time the ship needed to do a 360 degree turn off the dock. Because of the Orion and GPO Sapphire activity across the harbour (see above) there was not room to go north about George's Island. Also the autocarrier Sunshine Ace (not pictured) was outbound from Autoport and so the cruise ship could not back out into number one anchorage and turn without blocking its course. The light breeze was likely not much of a factor in this case, but cruise ships are subject to windage and must be handled accordingly.
