Cautionary Procedures: Taking on fuel at a dock can be dangerous if caution isn't taken beforehand. Please extinguish all fires, close all vents and place the metal nozzle firmly against the edge of the fuel tank intake pipe. Please follow any special fueling instructions given to you by a dock attendant. He or she has safety in mind.
Diesel: Diesel fuel is available at many but not all public docks. At some docks, diesel delivery can be arranged through the dock attendant when advance notice is given.
Credit Card Use: At most state-operated harbors, Visa, MasterCard and Discover will be accepted for all services. However, when fueling your boat, some harbors accept only credit cards of the company providing the fuel. Prior to fueling your boat, please make certain that your credit card can be honored. Some harbors accept dockage fees on credit cards only when fuel is purchased.
Boaters are asked to please use charts for the areas in which they boat. By having the information presented on charts, many unmarked hazards can be avoided. Charts are available from many commercial marinas or by mail order from agencies on page 14.
The latitude and longitude for each harbor entrance is printed on each individual harbor page, which begins on page 23, for electronic location systems use. In most cases, the stated location is in the lake near the breakwater entrance. For each harbor that is located up a dredged channel, two locations are given: the lakeward end of the entrance channel and the marina itself. For Bay City (Saginaw River), the listed channel entrance location is where the buoyed shipping channel intersects the 12-foot depth line on the chart.
Boaters are encouraged not to rely solely on any one navigational method or technology, including the location information provided in this guide.
