Commercial kayaking now seems to have been established at Sandy Balls Holiday Centre, on the River Avon at Godshill, just upstream of Fordingbridge. 

SU148133 A typical Avon scene. Reeds, willows and a fishing jetty
SU148131: There are two weirs at Bicton, one beside the mill, and this one a few hundred metres upstream. We portaged the first weir, easier and more discrete than the hatches by the mill (this would be runnable in a kayak in normal flows)
SU147125: Fishermen's hut
A relatively upmarket fishermen's hut beside the Avon near Bicton
SU147111: River Avon
A swamped boat and a fishermen's hut amongst the willows
SU150100: River Avon above Ibsley. Trees growing at an angle, presumably because of the prevailing wind in this open stretch of meadows beside the Avon
SU150097: Ibsley Bridge
SU149096: Ibsley weir
SU138077: Attractive meanders through Somerley Park. The swirling waters demonstrate that the flow is surprisingly fast for a mature river
SU146056: Not the most attractive part of the river Avon. This electricity sub-station on the east bank, close to the A31 and its bridges over the river, make a stark contrast to the rural scenes above and below Ringwood
SU145056: These hatches, with a bridge above, are beside the busy A31 at Ringwood
SU142051: Old Bridge over the Avon at Ringwood This bridge carried the old road west from Ringwood over the river Avon. The view from the other side is much less attractive, where the two carriageways of the A31 by-pass each has its own concrete bridge. The central support of one can be seen here, through the centre arch
SU141048: Old railway bridge at Ringwood
SU139033: River Avon above Avon Castle
SU138030: Avon Castle
SU133008: Pumping StationThis pumping station is on the west bank of the river Avon, beside the A338. The sign warns passing boaters to keep clear of underwater apparatus
SZ139998: Shooting Hide beside the river Avon
SZ145992: River Avon
SZ149977: Avon Causeway bridge
SZ156964: River Avon between Sopley and WinktonThe gatehouse to moorlands Bible College is the building just right of centre, in this view from the river
SZ160956: Hatches on the river Avon below WinktonThese hatches connect the east and west branches of the river Avon, which divides at Winkton and converges again at Burton. The function of the thatched building is not known to me
SZ157944: River Avon at Fairmile
SZ154940: River Avon above Christchurch waterworks

We saw very few people. A farmer on the Somerley estate got on his mobile as soon as he saw us, a game angler threw a comment after we had passed, a walker said hello, and four Environment Agency workers launched a boat as we passed, motored past us at Avon Castle and were working on the bank as we passed them again. They were very friendlyWe paddled my open boat from Fordingbridge to Christchurch on Monday, 23km as the crow flies but 37km on the water. We launched at 9 and arrived at Christchurch at 4, having struggled against a strong head wind all the way, but with surprisingly fast flow – faster than the stretch we are familiar with around Downton.
All was well until we reached the Christchurch waterworks, where the hatches must be portaged. As we portaged we were challenged by one of their staff who said we were trespassing, and he crossed the bridge to meet us. We launched ahead of his arrival to avoid conflict and were met at the next bridge by one of his colleagues who took photos and told us he would confiscate our boat if he saw us there again. Both were quite unfriendly in their approach and very confident of their position. This is a difficult portage to make discretely and, although the portage across the hatches is on the Avon Valley Path, and therefore a right of way, you have to cross a small piece of their land, the grass bank, to launch again. Presumably they could prevent that if they saw you coming, or threaten to sue for trespass if they knew who you were?
Other than that, a great day out, lots of bird life below Ringwood, and a very pretty piece of countryside. We thoroughly recommend it.
