We had a Zanussi washer drier on Sanity but rarely used the drier function, too expensive on water and electricity.
On Sanity Again we have a Zanussi Studio machine, smaller load but big enough for our needs.
On fine days I have a whirligig that fits on the stern (after we've moored up!). On wet days I hang washing on hangers from a rail that Bruce has fitted to the engine room ceiling.
