Research vessels (my favorite kind of unusual boaty type things):
Oregon State University's R/V Elakha, outbound from Newport, OR
NOAA's R/V McArthur II
"The ship conducts oceanographic research and assessments, throughout the eastern Pacific, including the U.S. West Coast, Central and South America. McArthur II is involved in studies in several of the National Marine Sanctuaries on the west coast of the United States. The 224-foot ship engages in measurements of chemical, meteorological, and biological sampling for several large scale programs within NOAA."
The Monterey Bay Aquarium Research Institute's R/V, um, Whatsername, Moss Landing Harbor, CA
R/V John H. Martin & R/V Sheila B., Moss Landing Harbor, CA
These research vessels belong to Moss Landing Marine Laboratories, which "administers the Master of Science in marine science program for California State Universities in northern and central California."
