She is - extremely so due to the fixed paddles (cannot work in opposite directions), very shallow hull, and tiny rudder. Extremely good seamanship by skipper and crew needed to berth her. But even then, will go wrong occasionally - and does.Lovely photos. She aways struck me as a very awkward vesssel to take alongside.

Apparently one solution if conditions demanded was to approach a pier at speed judging the moment to throw her into reverse to gently come alongside. Often he said you'd see folk on the pier retreating somewhat as they saw the initial approach speed then relax as they saw the way being taken off.
I did in fact remark that she "seems to be coming in awfully fast" when she was approaching Gravesend on Monday!
WAs this the Paddle Steamer that was laid up on the River Medway marshes some years back ?
'Allision', allision, old boy. That's what happen here on the East Coast.Ahoy Capt Matt , did you have your camera on 'Camera Shake' ready for the bump /collision , then ?
No, that's the Medway QueenWAs this the Paddle Steamer that was laid up on the River Medway marshes some years back ?
She is. Pretty much every pier she uses has had a ding from her at some time or another. The problem is that she has a very small rudder, and of course, there's no prop-wash over it, so rudder authority at low speed is minimal; she's basically unsteerable until she's got speed up. Also, of course, it takes a little while for the engines to reverse; no shoving the Morse control from forward to back! She looks lovely under way, but she's a nightmare in close quarters. In the Clyde she's well known as a vessel to keep well clear of in close quarters. I had a few worrying moments once in Rothesay Harbour; she was alongside and had to be manoeuvred out of her berth - and I was on a pontoon opposite her berth! All done using warps ashore along the lines of springing off a pontoon. All went well that time, but even then I knew her reputation.Lovely photos.

I understand that there are safety reasons why the paddles on a steamer like the Waverley are fixed; apparently, it is possible to overturn a paddle steamer where the paddles can operate in opposite directions. I've been told that paddle tugs could have independently operated paddles.She is - extremely so due to the fixed paddles (cannot work in opposite directions), very shallow hull, and tiny rudder.

Intended to go into piers that were designed specifically for steamers in the Clyde etc - which typically had room to abort and go rLund again. Rather more problematic when visiting piers designed for modern ferries.
I was given to understand that in the early days, some paddle steamers were fitted with the ability to operate the paddle wheels independently, but that it turned out to result in more problems than it solved, not least dangerous instability. Obviously operating them both on one shaft is mechanically far simpler, too, but there are obvious schemes to do that would not be substantially more complex - for example, instead of having two pistons connected to one shaft, split the shaft and have one piston on each shaft. That would probably come with an efficiency cost. Someone here once pointed out that paddle tug boats sometimes had independent paddles.While it may be a good idea for safety not to contrarotate the paddles, paddle steamers are that way because nobody had worked out how to build a transmission for the steam engines when they were built. Effectively the hull was the crankcase and the crankshaft was installed athwart the hull, generally a two cylinder arrangement with one main bearing amidships and one on each side, The ends of the crankshaft poked out through the sides of the hull into the paddle boxes and the paddles were bolted onto the ends of the crankshaft, If the engine runs ahead, both paddles go ahead and vice versa. to contrarotate the paddles would mean cutting the crankshaft in half! Early propellor driven ships were equally without a gearbox, the propellor shaft being bolted solidly to the crankshaft of the engine, be it steam or diesel. It was a long time before gearboxes became capable of handling ship engine amounts of power, diesels were cunningly arranged so they could be run rotating either way, just as steam engines had before them.

I did this trip last year and would agree with everything you say ,,,,,, although 11 hours was a long day and we were getting a bit bored by the time we arrived at Tower Bridge. The final move through Tower Bridge was quite spectacular, and the highlight of the trip ....... as you say the commentator was first class, and well informedIt's a fantastic day out.
We went from Harwich to Tower Bridge.
There was also a guide on a mike giving all the history of the Thames River and buildings.
