Recently used the Thames Clipper service, and was a little surprised:
The ships can go very fast through the water but large amounts of time are lost at the frequent stops, where the crew have to tie ropes to mooring bollards, deploy a boarding ramp, and then wait for long queues of passengers to file on and off;
The mooring/boarding situation with Thames Clipper seems to vary. Sometimes they fully moor up and use both ramps, sometimes they only moor the front or rear and then use a single ramp (often with no consistency on whether front or rear is used), other times I have been on them and they have slowed down for a pier, checked if anyone was there, then continued if they don't see anyone. The latter used more at nights.
The queues for the Clipper aren't helped by single file ramps (wider ramps may speed things up slightly) and slow Oyster readers which are often set just to the side too, so it's not a quick tap and go situation.
Timetabling might be difficult as there are probably big variations in patronage (many more on nice sunny days) making it hard to allow the right amounts of time for loading and unloading.
Thames Clipper suffers from a godawfully complex timetable. The 'routes' are useless as almost every single trip calls at different piers, such as the RB6. And on Saturdays, the RB2 some trips stop at Westminster Pier, some don't. For the sake of an extra 2 minutes to the journey time, they could have a lovely and simple timetable. The clipper timetable couldn't be much worse if it was timetabled by First Groups new AI bus scheduling software!
Time was also sometimes lost due to waiting in midstream for other ships to leave enough mooring space at piers.
Not helped by often TFL seemingly allocating minimal boarding spaces for Clipper. 1 space just isn't enough given the number of trips using some piers.
I left wondering if this service is a too-uneasy compromise between the 2 functions of providing a scenic cruise and providing a commuter service. For the tourists, the Clipper service is cheap; but a slower but less frequently stopping service on purpose-built tour ships with better visibility would be preferable. For the commuters, the Clippers are expensive and on some routes slow, compared to alternative modes like the Tube.
Clipper do what they want due to no competition and seeming lack of care for customers. Clipper clicked onto the fact that many people were using them as a cheap tourist ferry and so their fares are now expensive. Want to travel in the central zone, one way? £9 please! Absolute rip off. Sadly the tourist ferry operators haven't tried to welcome more types of travellers, (instead only wanting tourists) and so, as always happens with companies with no competition, they are generally nowhere near as good as they could/should be.
Clippers timetables are a mess, reliability can sometimes be really poor (Every time the Thames Barrier is up, Barking Riverside and Woolwich get abandoned, rather than keeping a ferry on the other side of the barrier to provide a basic shuttle, nope, you just get no service and the alternative transport modes aren't really there either (not exactly useful for passengers), sometimes lack of capacity. Too slow in some areas, I agree. Lack of updates on cancelled trips or late trips. Complex fare system where fares change quite a lot depending on where you buy your ticket (Oyster isn't always cheapest too which makes it even more confusing)
It's a network that is now seemingly operated just to rinse tourists and irregular travellers, rather than provide a lower priced, frequent, useful riverbus service.
The Hamburg ferries manage fine with n
o ropes and an automated ramp - however they don't have to content with the formidable tidal flow of the Thames.
The manual ramp will likely quicker, and being shore mounted, I know it was in Merseyside.
