Hammerton's Ferry is the only regular service on the non-tidal Thames (running between Marble Hill Park and Ham House) that is not completely shut down for six months, and is the only service on the non-tidal Thames between Hampton Court and Putney which restarts its services earlier than April 1st.

This service runs from early March to early November (£2 each way) and I recall seeing this service in operation during a visit to Ham House in mid-March 2024.

While there is another campaign I am focusing on at the moment, we need to get as many signatures as possible before October 2026 to prevent another six-month shutdown of services on the non-tidal Thames.
