23 is a historic sail-powered fishing vessel, now on display at the Lake Clark National Park and Preserve visitors center in Port Alsworth, Alaska.

Built in 1914, she served in the salmon fishery of Bristol Bay until about 1951, owned by the Libby's cannery and worked by two-man crews.

Despite its use for freight and recreation between 1953 and 1997, the boat has retained much of its original equipment, and was fully restored by the National Park Service between 1998 and 2005, acquiring replacement parts from similar boats and removing an added motor.

It is normally rigged with a mainsail and spritsail, but these are only raised when the boat is taken out of its custom-built boathouse.
