Luna Retires After Over 40 Years of Service
As more powerful diesel tugs and diesel-electric tugs were delivered to Boston Towboat, the Luna was gradually relegated to "back-up" status and was retired in 1971. Plans were made to sink the tug in Massachusetts Bay, but the tug was sold as an office and floating home, until it was acquired by a non-profit research institution in 1979.

The Luna’s fortunes declined over the next 16 years, until the Luna Preservation Society took responsibility for her in 1995. Luna was declared a National Historic Landmark in 1988. Now, the Luna is is being prepared for her role in Boston Harbor as an operating Landmark and educational vessel. (previous)
