Uxbridge: Where the Grand Union Canal Meets the Colne Valley
Uxbridge marks a significant waypoint on the Grand Union Canal's journey from London to Birmingham, positioned at the edge of Greater London where urban development gives way to the green spaces of the Colne Valley. This West London location serves as the gateway to the canal's rural character while maintaining excellent transport links to the capital, making it an ideal base for both residential moorings and cruising boats exploring the network.
Strategic Position on the Grand Union Canal
Located 18 miles northwest of Brentford and 119 miles from Birmingham, Uxbridge sits at a crucial transition point on the Grand Union Canal. To the south, the canal maintains its urban character through Hayes and Southall. To the north, the waterway enters the Colne Valley's parklands, meandering through countryside that feels remarkably remote despite lying within Greater London's boundaries.
Uxbridge Lock (Lock 88) marks the beginning of a northward lock-free stretch extending to Cassiobridge, allowing easy cruising through the Colne Valley. This extended pound proves popular with day boats and cruisers seeking relaxed navigation without the demands of frequent lock operations. The lock itself features the wide 14-foot beam characteristic of the Grand Union Canal's southern section, accommodating widebeam cruisers and traditional narrowboats alike.
Cowley Peachey Junction and the Slough Arm
Just south of Uxbridge, Cowley Peachey Junction represents a significant navigational decision point. Here, the 5-mile Slough Arm branches westward from the Grand Union main line, offering a completely lock-free cruising experience to Slough Basin. This arm provides an attractive weekend destination for boats based at Uxbridge, with the round trip achievable in a long day or leisurely weekend.
The junction area features the distinctive Packet Boat Marina, one of the premier facilities on the southern Grand Union Canal. Originally developed around the historic packet boat services that carried passengers and mail, the marina now serves pleasure craft while maintaining connections to its commercial heritage. The site includes the Packet Boat pub overlooking the junction, a traditional canal-side establishment popular with boaters and walkers alike.
Marina Facilities and Moorings
Uxbridge offers several mooring and service options:
Packet Boat Marina: The area's flagship facility, located at Cowley Peachey Junction. Provides secure berths, diesel, gas, pump-out services, and chandlery supplies. The marina specializes in narrowboat sales and brokerage, with a wide selection of both new and pre-owned vessels typically available.
Uxbridge Boat Centre: Situated near Uxbridge Lock, offering mooring, boat repairs, and engineering services. Particularly valued for its engine servicing capabilities and electrical work—essential for maintaining older narrowboats common on this section of canal.
Denham Marina: Located just south of Uxbridge, providing additional berthing options and services. Serves as an alternative for boats unable to secure Uxbridge moorings.
Canal-Side Moorings: Visitor moorings exist at several locations around Uxbridge, typically with 48-hour or 14-day limits. These provide convenient access to town center shops and services.
The Colne Valley Character
The Colne Valley gives this section of the Grand Union Canal its distinctive personality. The River Colne runs roughly parallel to the canal, with multiple channels creating a complex wetland environment. Nature reserves, gravel pit lakes, and water meadows line the canal, supporting diverse wildlife including herons, kingfishers, and seasonal water birds.
This rural character influences boat cover requirements. Tree coverage creates shade that protects boats from summer UV exposure but deposits leaves and sap requiring regular cover cleaning. The valley's microclimate can produce heavy dew and frost, making waterproof, breathable cover materials essential to prevent moisture accumulation and mildew.
Boat Types and Cover Requirements
Uxbridge moorings accommodate diverse boat types reflecting its transitional location between London and the Midlands:
50-70 Foot Narrowboats: The most common type, ranging from traditional working boat replicas to modern cruisers. Most require comprehensive cockpit tonneau covers and winter bow protection.
Weekend Cruisers: Shorter narrowboats (40-50 feet) owned by Londoners using Uxbridge as a convenient base for weekend cruising. Often feature canopy extensions providing outdoor living space during summer months.
Residential Boats: Year-round liveaboards requiring robust cover systems for weather protection. Full-length canopies and winter covers prove essential for comfortable living.
Hire Fleet Boats: Several hire companies base fleets at Uxbridge marinas, providing beginners with well-maintained boats for exploring the Grand Union Canal and Slough Arm.
Cover specifications must address Uxbridge's particular conditions:
- UV Resistance: Summer sun exposure requires fade-resistant materials like Sunbrella or equivalent marine-grade fabrics
- Waterproofing: Heavy rain and valley fog demand superior water repellency with sealed seams
- Breathability: Prevents condensation buildup in the valley's humid environment
- Secure Fixing: Wind funneling through the Colne Valley can create sudden gusts requiring robust fastening systems
Hillingdon Canal Club
The Hillingdon Canal Club, based near Uxbridge, represents one of the area's key boating organizations. Established in the 1970s, the club promotes canal use, organizes social events, and maintains portions of the canal environment through volunteer work parties. Members receive reciprocal mooring rights at other clubs nationwide, extending cruising opportunities throughout the network.
The club's presence ensures high standards of canal maintenance and boater behavior around Uxbridge, contributing to the area's appeal as a mooring location. The clubhouse provides social facilities including a bar, meeting rooms, and information resources about the Grand Union Canal and wider waterway network.
Historical Context
Uxbridge's canal history dates to the Grand Junction Canal's original construction in the 1790s. The town already served as a major coaching stop on the road from London to Oxford, so the canal's arrival reinforced its role as a transport hub. Warehouses and wharves developed along the canal frontage, with narrowboats delivering coal, timber, and manufactured goods.
The packet boat services that gave Cowley Peachey's marina its name operated express passenger and mail services between London and Birmingham, overtaking slower freight narrowboats and maintaining strict schedules. These services continued until railway competition made them economically unviable in the mid-19th century, though their memory persists in place names and pub signs throughout the canal network.

The No VAT Postal Service
Our boat cover service provides Uxbridge boat owners with maximum convenience through our postal collection and delivery system—no VAT charges on all orders. Whether moored at Packet Boat Marina or on Uxbridge's canal-side visitor moorings, simply post your old tonneau cover, spray hood, or canopy to us. Within six working days, you'll receive an exact reproduction crafted in marine-grade materials suited to the Colne Valley's conditions.
We understand Uxbridge boats often feature specific color schemes matching traditional working boat heritage or modern aesthetic preferences. Our pattern-copying method ensures perfect dimensional accuracy and, where possible, color matching to maintain your boat's visual appeal.
Seasonal Considerations
Spring (March-May): As temperatures rise, boat owners return from winter hiatus, often discovering cover wear requiring replacement. Spring also brings tree pollen and blossom debris that can stain covers if not regularly cleaned.
Summer (June-August): Peak boating season sees heavy use of Uxbridge Lock and moorings. UV exposure intensifies, testing cover materials' fade resistance. Many owners cruise north to explore the Midlands or south to visit London via the Paddington Arm.
Autumn (September-October): Excellent cruising weather with fewer boats on the water. Falling leaves from the Colne Valley's extensive tree coverage can accumulate on covers, requiring regular removal to prevent staining and moisture retention.
Winter (November-February): Wet, cold conditions test cover quality. Frost can damage poorly protected boats, while extended periods of rain test waterproofing. Our 6-day turnaround service ensures boats receive replacement covers quickly, even during the winter months.

Cover Maintenance in the Colne Valley Environment
The Colne Valley's combination of waterside location, tree coverage, and variable weather creates specific challenges for boat covers:
Tree Sap and Residue: Regular cleaning prevents permanent staining. We recommend monthly cleaning during tree-growing seasons using approved canvas cleaners.
Moisture Management: Breathable cover materials prevent condensation while maintaining waterproofing. After extended rain, allowing covers to dry completely before storage prevents mildew.
UV Protection: Despite tree shade, UV exposure remains significant. Quality marine-grade fabrics with built-in UV resistance last significantly longer than economy alternatives.
Secure Fastening: Wind gusts through the valley can lift inadequately secured covers. Double-check all fasteners before leaving boats unattended, especially during autumn and winter when storms become more frequent.
Our postal service has served Uxbridge boat owners for years, with customers appreciating the convenience of sending covers from Packet Boat Marina or Uxbridge Boat Centre via standard post. The 6-day turnaround minimizes the time boats spend without protection, while our VAT-free pricing provides better value than high-street alternatives.
