Left Bank through marina is Hennerton Backwater upstream entry under a very low bridge (lie down in a punt and even duck in a canoe)
The boatyard is on the upstream end of the island formed by the river and the Hennerton Backwater.
Upstream of it is another, nameless? island, with a bridge over the backwater entrance to the marina.

On the LEFT bank just above the George & Dragon was a boatyard which has now been redeveloped as flats. From the Henley Standard, June 2008 -

The Riverstation is situated on the edge of the village, set back from the road on the riverbank adjacent to the St George and Dragon restaurant, and is newly constructed and immaculately presented, with furnishings by Brook House in Henley. Many of the rooms have wonderful river views, with underfloor heating which is independently controlled in each room. The principal living area on the ground floor is arranged around a vaulted central reception hall with a floating wooden staircase, Velux-style windows and glazed doors, leading onto a split level sun deck which overlooks the river, and can be reached from most of the rooms.
