===Refits and renamings===
{{Unreferenced section|date=July 2024}}[[File:Mersey Ferries, East Float, Wallasey - geograph.org.uk - 1405261.jpg|thumb|right|{{MV|Royal Iris of the Mersey||2}} and {{MV|Snowdrop||2}} berthed at East Float, Wallasey]]
The ''Overchurch'' was given her major refit in 1998 at Lengthline Ship Repairers in [[Manchester]], which resulted in a major rebuilding of all decks and fitting of new engines and navigation equipment. She was renamed {{MV|Royal Daffodil|1962|2}} and returned to service in 1999. ''Mountwood'' and ''Woodchurch'' were also refitted and renamed {{MV|Royal Iris of the Mersey||2}} and {{MV|Snowdrop||2}}, respectively in 2002 and 2004. The ferries were re-designed by their original architects - Graham and Woolnough. When all three vessels were refitted, the previously used [[Steering wheel (ship)|helms]] and binnacles with compasses were placed back on the refurbished bridges. The current two ferries have been in service for over 60 years, with 2019 marking the 60th anniversary of the launching of ''Royal Iris of the Mersey'' and the ''Snowdrop''. The refitting of the ferries has extended their working lives by approximately thirty years, and this is steadily increasing with additional repairs that are carried out on the boats on a regular basis.

The [[Wärtsilä]] engines installed on the ferries during their last major refit are much more economical than the previous engines by Crossley Bros of Manchester. They are also much 'greener' and produce much less emissions than the original propulsion units.

The ferries' masts now carry several other navigation lights on their main masts at various points. Prior to refit, they had only a forward-facing white light. This is due to the classification of the ferries.

The ''Snowdrop'' and ''Royal Iris'' each carry two Kockums Super Tyfon TA 100/165 type fog horns. ''Royal Daffodil'' carries two Kockums Super Tyfon TA 100/195 horns. These are the original horns fitted when the ferries were first built. Both ''Royal Iris of the Mersey'' and ''Snowdrop'' have an [[E♭ (musical note)|E-flat]] tone, and ''Royal Daffodil''{{'}}s is in F Sharp. When berthing the vessel, the captain uses a combination of rudder positions and engine movements. The ferries all have twin rudders and propellers, making them very manoeuvrable.

The Mersey Ferries used to operate in fog, however, the service is usually suspended when visibility is very poor.
