On today’s schedule, we have a loaded ship heading downriver, and then stopping part way for awhile, before cointinuing to Astoria and out to sea.
She’s doing something unusual – it’s called two-part sailing. It’s when a ship doesn’t have enough water under her keel at some point in her outbound transit and has to stop and wait for the tide to rise. That’s what this ship is doing for safety. When the rising tide gives her more water under her keel, she’ll head safely out to sea.
Two-part sailing is one of the many ways pilots keep ships safe in their transits on the river.
