Fueling Ferries

Many of our customers want to know how often we have to fuel our vessels. The fleet is so diverse that the answers vary considerably. For example, a smaller vessel such as the Rhododendron would refuel about once a week, taking on approximately 3,600 gallons. The Rhody's tank capacity is approximately 11,250 gallons, burning about 30 gallons an hour. On the other end of the ferry spectrum, we have the Jumbo Class ferries, the Spokane and Walla Walla. They refuel about every two weeks and take on approximately 50,000 gallons, using about 240 gallons an hour. Their tank capacity is about 135,000 gallons. It is said that the Issaquah Class ferries hold enough fuel to cruise from Seattle to Japan without refueling.

Port Townsend/Coupeville sailing adjustments for tides

Extreme ebb tide currents, 3.5 knots or more, cause steering and control problems for ferries entering Keystone harbor.

Entering the narrow end of a teardrop-shaped harbor, steering is crucial. Extreme currents can make the boat "spin," increasing the danger of going aground. As the bow of the boat passes the entrance to the harbor, the stern, still in the current, is buffeted and pushed north, making it difficult to maintain course.

The solution to the problem is to find when the current is 3.5 knots or greater, and avoid being in the wrong place at the wrong time. We consult tide and current tables to determine the hours of greatest activity, consider the experience of our captains, then cancel or delay the sailings that would be at risk. Fortunately, we are able to determine well in advance which runs will be canceled on the Port Townsend / Coupeville route due to this tricky tide and current situation.

Does the system work?
Yes. The traveling public understands the concern for safety, and appreciates the opportunity to plan ahead and minimize the inconvenience.
