One of these builders was Luke & co, later Luke Bros, a reputed yard at Hamble from around 1890 to 1945. The river, and its shipbuilding yards have also been used for military purposes, particularly during World War II. Its lower reaches are popular for boating, being known throughout the sailing world as The Heart of British Yachting.
From its source near Bishop's Waltham, the river flows in a generally southerly direction picking up several small tributary streams before reaching Botley, the site of an ancient watermill.
Botley to Bursledon (tidal) - historic sites
Below Botley, the river becomes tidal and navigable. It gains strength from adjoining streams, draining the surrounding areas of Hedge End, Curdridge, Shedfield, and Burridge. This section has been extensively used for medieval shipbuilding, using timber grown locally in the neighbouring woods. Nearby Kings Copse, formerly Kings Forest, indicates the former importance of this area. The river's west bank can be accessed from Manor Farm Country Park, where it is possible to walk through Dock Copse and Fosters Copse. At extreme low tide, it is just possible to see the remains of the wreck of Henry V's 15th century warship Grace Dieu. This section of the river was also home to HMS Cricket during World War II. Some 2 miles south of Botley, the river passes between the villages of Bursledon and Lower Swanwick and is crossed by the M27 motorway, the Portsmouth to Southamptonrailway line, and the A27 road on three substantial bridges.
Bursledon to Hamble (tidal) - modern playground
A further 2 miles south of Bursledon, the river flows between the villages of Hamble-le-Rice and Warsash before entering Southampton Water. A passenger ferrycrosses the river between Hamble-le-Rice and Warsash, forming an important link in the Solent Way and E9 European Coastal Path. The river is also the location for several large marinas, the largest being the Port Hamble Marina and boat yards, situated on both banks as far upstream as Bursledon. In the 1970s and 80s the large number of yachts in this area resulted in significant pollution from tributyltin used in anti fowling paints. By 1988 the area had the highest known level of tributyltin pollution in the UK. With the banning of tributyltin for vessels under 25 meters the levels of tributyltin began to decline towards levels considered harmless.
