The Black Sluice Navigation, also known as the Forty Foot Drain, offers 31 kilometers (19 miles) of navigable waterway into the western part of Boston, Lincolnshire. This artificial drainage river, which was dormant for nearly four decades, was re-opened to traffic in 2009. It stretches from Guthram Gowt to the Black Sluice pumping station, located on The Haven at Boston, providing a distinctive Fenland navigation experience.

Operating under specific Lincolnshire waterway regulations, the Black Sluice Navigation requires all vessels to obtain a valid registration for use. Boaters have the option to purchase either a 1-day or a 7-day visitor registration, catering to both short-term and slightly longer excursions. To secure the necessary permit and acquire a navigation key, which grants access to moorings, individuals must contact the Environment Agency directly at 0370 850 6506. Further details and mapping tools, including the Black Sluice Navigation useful guide, are available for planning journeys along this unique UK inland navigation.

Accessing the Black Sluice Navigation from the tidal Boston Haven necessitates passage through the Black Sluice Lock. This critical entry point requires advance planning, as the Environment Agency mandates at least 48 hours' notice to arrange staffing for lock operations. Bookings for the Black Sluice lock booking procedure are strictly dependent on prevailing tidal conditions and can only be accommodated during suitable daylight locking windows. To initiate a booking request, boaters should call 07825 503 848.

Navigators must be aware that bookings may be subject to postponement or cancellation due to unforeseen circumstances, though the Environment Agency endeavors to provide as much advance warning as possible. For general inquiries or if direct lock contact is unsuccessful, the Environment Agency Customer Contact Centre can be reached at 03708 506 506 during normal office hours; they will forward queries to the Lincolnshire and Northamptonshire Anglian Waterways Operations Team. Immediately after exiting the Black Sluice Lock, vessels pass under the London Road Bridge, an arched structure with a variable height restriction ranging from approximately 1.7 meters to 3.4 meters, with specific details available in the London Road Bridge profile.

Throughout the Black Sluice Navigation, several bridges present low headroom challenges. On average, at normal summer water levels, these structures offer around 3 meters of clearance. Inverted gauge boards are strategically placed at lower sites to clearly indicate the available headroom, placing the responsibility squarely on the skipper to verify sufficient clearance before proceeding. Beyond Donnington Bridge, access is significantly restricted to small unpowered vessels, such as canoes and kayaks, due to limited water depth, narrow width, reduced headroom, and important environmental and wildlife considerations.

The section of river between Grand Sluice Lock and Black Sluice Lock is tidal, characterized by strong ebbs and flows. Navigating this particular stretch demands extreme caution, especially given that larger commercial vessel Black Sluice traffic may also be present. For enhanced safety, mariners are advised to tune into channel 74 on their VHF radio to monitor boat traffic when traversing The Haven. While there are no permanent moorings along the Black Sluice Navigation, short-stay moorings are available at Boston, Swineshead Bridge, and Hubbert’s Bridge, with a maximum stay limit of 48 hours at each location.

Adherence to UK inland navigation compliance is paramount for all users of the Black Sluice Navigation. Skippers are responsible for understanding and following all Forty Foot Drain navigation requirements, including those related to vessel registration, lock booking, and bridge height restrictions. Current river conditions, including any closures or restrictions, are regularly updated and accessible via Anglian Waterways resources.

For additional information or specific queries regarding the Black Sluice Navigation rules UK, boaters can contact the local river inspector at 07825 503848 or 03708 506 506. Comprehensive information, including a Fens Waterways map and details about the Boston to Peterborough Wetland Corridor, can also be found on the Inland Waterways Association website, ensuring all users are well-informed for a safe and compliant journey.

Lawyers and compliance officers advising clients involved in commercial or recreational activities on the Black Sluice Navigation should review these updated operational guidelines. This ensures adherence to Environment Agency requirements regarding vessel registration, lock booking, and bridge height restrictions, thereby mitigating risks of non-compliance and potential penalties.
