R/V Parke Snavely

The USGS Pacific Coastal and Marine Science Center acquired vessel Parke Snavely in November 2007. Snavely is a 34’ Armstrong Catamaran with an open stern and an aluminum hull. Her beam is 10’6” and she drafts 3’9” (1.5 meters). She features a self-bailing welded aluminum deck, removeable boarding, port-side dive door, and internal sea chests. 

The boat is named after Parke D. Snavely, Jr. (1919 - 2003), a pioneer of marine geology research at USGS.

Snavely is principally a seafloor mapping boat, used in many seafloor and nearshore operations:
