The Adventure was a sloop maritime fur trade ship built by the crew of Captain Robert Gray on his second voyage to the Northwest Coast of North America. The 45-ton sloop was built to allow the trading venture to access smaller inlets the Columbia could not reach. At the end of his second voyage Gray sold the ship to the Spanish Navy. It was renamed Orcacitas (also spelled Orcasitas or Horcasitas) and served the Naval Department of San Blas for some years.
