In a statement issued through Kent Police, Mr Wallace’s family said he “deserved a better end to his life than this”.
They said: “He had been married for 63 years, was a father of three, a grandfather of four, and recently a great grandfather.
“He sailed his boat up and down the east coast, and across the Channel to France, usually single-handed. He was a bell-ringer at the church on Gillingham Green. He was a Samaritan for many years, raised money for the NSPCC and undertook several European cycling tours to raise funds for Marie Curie.
“The residents and postman who tried to help in Grange Road were compassionate and kind. Our thanks and appreciation go out to them.”
Kent Police has further confirmed that, during the course of inquiries into the fatal crash, officers attended an address in Dartford which was found to contain a cannabis cultivation, with a man arrested at the scene.
Ronalt Kamami, 28, of Dale Street, Chatham, was later charged with production of cannabis and appeared in court on Wednesday.
He has been remanded in custody until his next appearance at Maidstone Crown Court on 26 January, the force said.
