Washington (STPNS) -- Two weeks after private whale-watching vessels were hired to provide ferry service on the Keystone-Port Townsend crossing, windy weather and low tides have caused significantly more cancellations than expected.

And with the holiday travel rush increasing the number of people seeking to board the smaller boats, ferry workers have found themselves having to intervene when aggressive travelers push ahead in the waiting line to try to assure themselves a place on board.

According to Washington State Ferries, 34 one-way trips have been canceled between Dec. 13 and Dec. 25, leaving many commuters and holiday travelers to make other arrangements to travel between Whidbey Island and the Olympic Peninsula. In some cases, the number of passengers exceeded the amount of indoor seating on the small tour boats, forcing people to stand in the aisle. And on several occasions during the Christmas holiday travel rush, passengers had to be left behind because the small tour boat was full.
