Sudbury to the Sea (S2C)

Sudbury to the Sea (S2C)

This popular event takes place annually over a weekend in September. Participants navigate the 24½ miles (37km) of the River Stour, from Sudbury to the Cattawade Barrier, enjoying its many delights and seeing parts of the local countryside that are inaccessible by foot or road.

It has been part of our calendar in one form or another since the 1970’s and was for many years known as ‘The Length of the River Cruise’. In 2005, it was re-branded Sudbury to the Sea although it is most commonly referred to using the acronym, S2C. The event was originally designed to ensure that the Navigation was used and to note any problems on the river. These are still important aspects but it is generally regarded as a social paddle.

Experienced and novice paddlers travel from all over the UK (and sometimes further afar!) to take part. The River Stour Trust provides help and advice along the route, a safety boat following all craft, and checkpoints at various points along the navigation. Participants must provide their own craft, personal safety equipment, transport at either end of the event, accommodation for the Saturday night (a camp-site at the midway stage), and food and drink. However, there will be some food and drink available at various places along the route.

All craft navigating the river and taking part in S2C must be registered to do so and all participants will be expected to abide by the rules of S2C.

About the River Stour Trust

The River Stour Trust is a registered charity (No. 257806), led by volunteers dedicated to the restoration and conservation of the River Stour Navigation for the benefit and enjoyment of the public.

You can help whether you choose to join us as a member, make a donation, and/or support our activities and events. This river has a long history which we hope you will help us preserve. We could not exist without our members and supporters – find out more.

For generations the River Stour occupied a central position in the lives of people living on its banks, both in work and play. It is one of the most attractive rivers in the country, winding through a wide pastoral and wooded valley past towns and villages of great beauty and with many historical associations.

We seek to reinstate through navigation, improve river access points and campaign for a change to the byelaws in order to permit electric boats on the whole stretch of the River Stour. We actively encourage use of the river and particularly promote the use of small and electrically powered craft that are silent in operation and environmentally friendly. We organise many river-based activities and fundraising events on or near the river, we operate river trips for the public and hold regular working parties to maintain the locks and structure in our care.

We have undertaken several successful restoration projects – Flatford Lock, Dedham Lock, Great Cornard Lock, Flatford Barge Dock (in association with the National Trust), the Quay Basin at Sudbury, Gasworks Cut at Sudbury and The Granary building at Quay Lane, Sudbury. We are currently working towards the restoration of Stratford St Mary Lock to open a further three miles of the navigation. We have built a Visitor Education Centre on the site next to Great Cornard Lock which enables visitors to learn about the history of the River Stour Navigation, its importance in Britain’s industrial and cultural heritage and the Trust’s own role in promoting use of this historic waterway. We rescued an original Stour Lighter which has been fully restored under the Managing a Masterpiece scheme.The next stage of its life will bring it back to being used on the River Stour as a trip boat and ‘floating classroom’ to be enjoyed by future generations.


A river with two names, is it pronounced Stower (rhyming with myrrh) or Stour (rhyming with hour)? The first thing to grasp is that the name of the river can be pronounced two ways and much debate rages on this topic! If you have a strong Suffolk accent then you will insist on Stower but there is really no uniform pronunciation. There are many other River Stour’s in England with the origins of the name deriving from Saxon times and referring to a “strong or mighty river”.

During the reign of Queen Anne in 1705, an act of Parliament was passed making the River Stower (Stour) navigable from Sudbury, Suffolk to Manningtree, Essex. This was one of the country’s earliest statutory rights of navigation. Between 1705 and 1713, work was undertaken to enable passage for barges, boats, lighters and other vessels. A public right of navigation remains today and is administered by the Environment Agency. However, many of the locks have disappeared and through navigation from Brundon Mill, upstream of Sudbury in Suffolk, to the sea at Brantham in Essex (a distance of approximately 25 miles) is only achievable to lighter craft such as canoes and kayaks. Scenes of the Stour busy with all kinds of boats have been immortalised and made famous by the renowned landscape painter John Constable (1776-1837).

The River Stour Trust was set up on 12th September 1968 to protect and enhance the right of the public to navigate the River Stour. We seek to reinstate through navigation, improve river access points and campaign for a change to the byelaws in order to permit electric boats on the whole stretch of the River Stour.

These barges operated on the River Stour from 1705 until the early part of this century carrying cargo up and down the river including bricks, grain, flour, manure and coal.

Most of the boats were made in a dry dock or Basin at Flatford although others were built on a boatyard at the top end of the former Gasworks Cut near the The Granary, Quay Lane. Sadly, its remains were destroyed in September 1997. However, the Basin at Flatford was restored to full working order by the National Trust with assistance from the River Stour Trust in the late 1980’s. John Constable’s famous landscape painting ‘Boat Building at Flatford’ (c.1815) shows a lighter under construction.

The lighters are unique in that they operated in pairs, being permanently shackled bow to stern, rather in the style of an articulated lorry,with the rear lighter being used as a rudder for the pair. The stern vessel had a single hold with a small cabin at the back. Each boat measured approximately 10 feet wide and 46 feet long with a depth of 2.8 feet and was able to carry a load of 13 tonnes. The crew consisted of a captain and a horseman, often a young lad, and the total 26 tonnes of cargo were towed by a single horse. The horse was trained to leap on and off the foredeck whenever the towpath changed from one bank to the other and jumped many obstacles that were encountered along the towpath. John Constable is well known for his paintings that depict the working life of the River Stour during the early 1820’s. ‘The White Horse’ (c. 1819) shows a horse being ferried across the river whilst ‘The Leaping Horse’ (c.1825) depicts the horse jumping over a barrier on the towpath.

The journey from Sudbury to the estuary normally took about 2 days, with an overnight stop halfway at Horkesley where a special bothy or bunkhouse was provided for the lightermen. The lighters continued upstream to Sudbury until the 1914-1918 War, when fearful of a German invasion, it was decided to scuttle the entire Sudbury fleet of 14 lighters in Ballingdon Cut. However, two separately owned lighters continued to operate on the lower part of the river until about 1938, when they were eventually abandoned.

One of the lighters (No.13) was recovered in the 1970’s by members of the River Stour Trust and was later the subject of a year long job creation scheme, where it was finally restored by a gang of five previously unemployed men.

In the 1980’s it was not only vandalised but also damaged in the Great Storm of 1987. It was moored at Great Cornard for many years in much need of funds to restore it to its former glory.

The John Constable Lighter is on the Historic Ship’s Register as being of regional historical interest and the River Stour Trust is proud of having preserved the lighter for posterity.

The River Stour Trust is delighted that this 140 year old vessel has been restored to full working order as part of the Managing a Masterpiece scheme. The next stage of its life will bring it back to being used on the River Stour as a trip boat and ‘floating classroom’ to be enjoyed by future generations.
