The USGS Pacific Coastal and Marine Science Center acquired research vessel (R/V) 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.

One of the unique features of our “big little boat” R/V Parke Snavely is that it can be towed by truck and trailer.
