Boston Marina (also known as Boston Gateway Marina) sits on the sunny side of the River Witham in the heart of Boston, Lincolnshire. It offers a convenient access point to both river and sea routes while remaining a short walk from the historic town centre.

The marina provides visitor, short-term, and longer-term moorings, with power and water connections available to all boats. On-site facilities include toilets, showers, and free parking.

Despite its central location, the site retains a notably tranquil atmosphere.
