pproximate Vessel Travel Times:
(Times vary according to tidal conditions, current, weather,
and individual vessel horsepower)
  • Portland/Vancouver -Astoria: 6-8 hours
  • Kalama -Astoria: 5 hours
  • Longview -Astoria: 3.5 hours
  • Columbia River Bar - Astoria: 1.5 hours

Tide Notes:
  • Tide times are often listed in 24 hour time - for times after noon, subtract 1200 from the time to get regular clock time. Ex: 1300 hrs - 1200 = 1:00 pm)
  • Also, tides are referenced to Mean Lower Low Water, a reference point for depth on many nautical charts. MLLW is the average of the lower of the two low tides in a day, over a 19-year cycle. Minus tides are lower than MLLW.
  • If you're right on the coast, subtract an hour from these times. Upriver, highs and lows happen later. For instance, in Knappa, add an hour. In Clatskanie, add 2 hours and 15 minutes.
Ship Horn Signals
Commonly Heard off Astoria:
  • One prolonged blast every two minutes or less: vessel operating in fog.

  • Five consecutive horn blasts:  warning signal that means literally "I do not know your intention." This generally means another vessel is in the way of a ship in the channel, and is being asked to move before they collide.

  • Three short blasts: Vessel going in reverse

  • One long blast followed by three short: signal for the change of pilots. Soon after this signal, you'll see the pilot launch Arrow II head out to a passing ship, to facilitate the transfer of bar and river pilots.
  • Note: "Pilot transfer" is when a pilot disembarks or boards a ship. Ships generally must by law have a river or bar pilot on board when they are on the Columbia or Willamette Rivers. The bar and river pilots have separate pilotage grounds defined by the Oregon Legislature.

The Marcus G. Langseth is a seismic research vessel owned by the
National Science Foundation and operated by Columbia University.
She spent several months in Astoria in the fall of both 2008 and 2009,
at the Port of Astoria. In early December, she headed to the shipyard
in Portland for some needed maintenance and repairs.
She headed back out to sea in early 2010.
