Many years ago my parents took me on a trip on the Waverley around Rothesay and the Kyle of Bute. While they spent their time admiring the scenery, I was in the engine room!
Me too! For a period of about 10 years, from age 5, every year I went on the Rothesay trip, and I always spent most of the time being mesmerised by the engine.
There is something hugely satisfying about seeing things revolving and hearing and sensing the throbbing power of the motion! The 'Ernslaw' on Lake Wakatipu is another of the same ilk but different machinery.
The paddle beats like the human heart ❤. That's why I like this boat. Not to fast like a lightning bolt but the way the wheel is spinning always make me felt a live.
I went on this yesterday and even though this is old technology I couldn’t believe how fast it actually went. Modern ships may be more fuel efficient but they don’t have their inner workings on display to the same extent, so it’s a great education too.
I went on the Waverly from Newhaven many years ago with my father. An amazing trip around the IoW despite loosing a playing card down the back of the seat and the worsening weather.
100 years ago, there used to be a large number of sidewheelers like this on the US Great Lakes. My mother took a trip on Seeandbee, a night stateroom boat, and my mother in law went on the Tashmoo, a legendary fast boat on the Detroit to Port Huron river run. Both had the same inclined triple expansion design. Also, there were some sidewheel rail car ferrys traveling across the Detroit River, Detroit to Windsor. One of them, Lansdowne, had the sidewheels not connected, with 2 separate engines, so she could steer like a Bobcat. I watched Lansdowne at both the Detroit and Windsor docks. Eventually, she blew a cylinder head, and was moved by a tug after that. During WW-II, 2 of the large sidewheelers were converted to small aircraft carriers for pilot training on Lake Michigan out of Chicago.
I enjoyed my voyage in The Bristol Channel ..This year .June 2023....Clevedon to Ilfracombe ...Loved it ...She is WONDERFUL...Waiting for her River Thames itinerary...Fingers Crossed...Douglas F Vick...Cheltenham Spa....
For those, like myself, who have little knowledge of the way in which paddle-steamers are operated, the following comments (from someone who served in one) might be of interest: ""With a paddle steamer one has to come in quickly - too slowly and one loses steerage. OK with a screw ship with the propeller next to the rudder which is quickly activated but on a paddler the propulsion is amidships and takes a long time for the flow of water to reach the rudder. I can well recall when I myself was Mate of a large paddle steamer in 1966 the Captain calling the Chief engineer to the Bridge and telling him that from the time he touches the engine telegraphs the paddles are to be turning in 3 seconds not 5. (Sometimes there was a harbour wall or similar directly ahead of the pier). Also when reducing speed, say from Half Ahead to Slow or Dead Slow Ahead, then the engineers should give the engines a blast of Astern steam to ensure that the engines are going at the ordered speed. . Also you will notice that in a paddle steamer the engine telegraph has TWO distinct sounding bells - one for Ahead movements and one for Astern movements. Screw-propulsion ships, IF indeed they have telegraphs which today they do not, just have the one sounding bell. However on screw-propulsion ships, if indeed there are telegraphs (as today manoeuvring is controlled by the Bridge directly) the engine telegraphs are there as a reply, so when the Bridge give the order then the engineers also move and ring their telegraph so the bridge knows the engines will turn the correct way. On paddle steamers, TWO distinct sounding bells are fitted to the engine room telegraph, so there will be no confusion at all as to which way the engines should be going. . Paddle steamers can stop very quickly - I know that the Bristol Queen , whose service speed was about 16 knots could stop in about ¾ of her length (if Full Astern was rung). BQ was built as an esturial steamer for the rough waters of the Bristol Channel - you will note she has portholes instead of windows, also her paddle floats were of steel as opposed to wood of the Waverley. However if a steel paddle float is damaged then that is a dry dock job whereas if a wooden float breaks, as happens from time to time, then the ship can proceed ok and the engineers will fit a new one when time allows. Bristol Queen was an excellent Sea boat whereas Waverley is really a river boat and not so stoutly built. I still have some pages copied of our Deck Log book. I can still recall proceeding down channel (Cardiff to Swansea) light ship ie no passengers in a full Westerly gale force 8. As you can imagine, in the BQ we got a little wet on the Bridge ! Waverley is not allowed to proceed if the wind force is 5 or above. BQ would have been the one to preserve but sadly she went to the scrapyard after only 20 years. The age of preservation had not yet then arrived. You will note that the BQ has concealed paddle boxes - not a particularly good idea as they easily become choked. When there were no passengers on board and we were proceeding in rough seas, the paddle box doors would be left open and the excess water would come in to the alleyway and out through the scuppers ! The MCA would have a fit today if they saw that! . Also in former times their were many pleasure steamers on the R Clyde both paddle and screw. A 16 knot paddle steamer could maintain the same service as a 21 knot turbine steamer, because the paddle steamer takes less time to dock and pull away - an advantage on short hops Also paddle steamers had a much shallower draft."
I wondered about the jacking gear, hadn't seen it before. Good to see they're keeping after her. First time I noticed that the crosshead shoes travel about an inch past the end of the crosshead guides. Suppose that's a way to shed dirt? We'll probably never get across the pond to see her, so these videos are a great substitute. Waverley is the closest we'll ever get to the long-gone fast Tashmoo, and the big sidewheel night boats on the US Great Lakes. These boats had the same inclined triple arrangement. Wonderful video, keep doing them!
SteamCrane When I worked on her, the engines were turned with block and tackle fitted on eyes in the sponsons, and attached to the float arms and turned by pulling the chain while standing on the narrow bearing platform directly above the water. It was hard manual work and you'd easily work up a sweat. My glasses fell off, much to the smusement if the chief: and are prop still there yet at the bottom of the river.
Wow! That's crazy. Wonder why they didn't have one from the beginning. You know you'll need to turn the engine sometime to do any work. Thanks for the info!
The crosshead guides travel past the guide itself in order to dip into the oil bath below on a vertical engine, probably the same on this one though you can't see the other end of the guide. Usually around 90% veg oil, 10% mineral oil, with a bit of water to emulsify it and make it stick to the guides. On many ships it was collected in the bilges and pumped out at sea (if an ocean going ship) or landed ashore, as it was a total loss system. Pumping out at sea would not be allowed these days even if it was 90% veg oil, but then, there are no ocean-going steam reciprocating ships left.

Very interesting this Reconstruction, very fine video. I think it's good if we do not let our technical history die out. Already too many old steamships have been killed. If you can not sleep peacefully without steam, you can also visit Germany. We still have nine really old side paddle steamer in Dresden (Elbe), one in Lauenburg near Hamburg (Elbe), one in Kiel (Baltic Sea) and one in Bremen (Weser). They are all well 100 years old, and in one ship (Diesbar) runs even the oldest, still in use steam engine in the world from the year 1841. ruclips.net/video/P31ZpP27Oyw/видео.html
At 1:00 Order "Ahead Stand By" means Astern (dead slow)? Cause that is the order, and that is what the engine looks like it is doing. What's up with this? EDIT: at 3:10 I was thinking the "New Turning Gear" would be an electric motor that replaced a steam engine,.. But I was wrong. Looks like one must engage that worm and lick it, then bring out the Crank. I am sure it is easy to crank though. Only need to move it at most one rev, and occasionally. I wonder how they positioned the engine before this was installed? Based on description, I guess the boilers had to be up and one had to slightly power the whole engine. But what if one needed to pull the first piston out? Interesting. The crank is the wtg.
Wonderful to see. But I’m curious about the crank throws, as a three cylinder, are they actually at 120 degrees out from each other? It appears, to me anyway, that there is a difference in the phasing of either outer journal when compared to the other using the center as reference. Thank you for posting, large steam engines are fascinating.
With the 3 cylinders in the same plane, the throws *should* be exactly 120 degrees, especially since the engine is reversible. On a non-reversing engine, the angles could be fudged for some performance reason. There is a massive sidewheel German river towboat, Oscar Huber, that the cylinders are *not* in in same plane, so the cranks are probably not at 120 degrees. I watched Waverley's engine turning from the cylinder end, and counted the time for each crank to go over top, and it *seemed* pretty regular. Possibly somebody in the engine crew could answer.
I am a complete ignoramus but fascinated. Can someone explain to me please why I can’t see the crank shaft? I don’t see particularly what the middle one is turning? Please help a fool and explain.
Oh it s there, where you see the three crank rods connected, that is the crank shaft. It extends out either side and is directly attached to the paddle wheels. This is why paddle steamers can be particularly difficult to manoeuvre at close quarters as both wheels either turn forward or astern together.
While not ocean-going, the Waverley frequently travels in open seas such as on the west coast of Scotland. On her trips down south to England she makes her own way down the Irish Sea, Bristol Channel, stopping at various places, before heading up the channel to SE England.
@@ryantimm9748only with a hurricane behind her on trips in 1947 when the engine was new she could do 18.5 knots at 56 rpm she could probably still achieve it today if pushed. Go on the last sailing of the season that is traditionally when they open her up.
@@srfurley Good question Stephen. I do not know the answer to that but believe it has to be pre heated to atomise in the burners so must be a heavy grade oil. I see someone who worked on the ship on a day out sometimes and will see if he knows or can find out for you
@@joewoodchuck3824 it has been very well preserved and it is muched loved here in Scotland and the rest of the UK. The summer day trips around the west coast of Scotland are fantastic.
Check out this video of the PS Maid of the Loch's engine for a simplified description of how the machinery works. Although only 2 cylinders as opposed to the Waverley's three, the theory is much the same. ruclips.net/video/yda4STR1Pe4/видео.html&spfreload=5
Yes, it's a triple-expansion engine. The steam is first admitted to the high-pressure cylinder, and after it has done its job is passed on to the middle one. Because the steam has lost some energy, the next piston has to be of larger diameter (and therefore area) to get the same amount of work out of the steam. The final cylinder, the low pressure one is even bigger for the same reason. After that the steam goes to the condenser to be reverted to hot water for re-use.
I live in Rothesay I've seen it many times ,ardlanont point tighnabruich all the litoral waters of west coast of Scotland you'll see that t nice sc nerdy well worth h going on
That chuff on steam locomotives is due to exhaust steam being expelled through the funnel. Steamships, however, traveling longer distances where freshwater is unavailable between stops, must hold on to their water supply as much as possible. Rather than expel it into the atmosphere, they send their exhaust steam to a condenser that cools it back to water. Water pulled from rivers, lakes, or oceans is usually too dirty or saltly to run in an engine without causing damage. However, devices such as evaporators can filter it, albeit in relatively small amounts.
Titanic's were vertical triple expansion, the normal for propellers. Waverley's inclined engines work well with side wheels, and the cylinders are low to lower the center of gravity.
Many years ago my parents took me on a trip on the Waverley around Rothesay and the Kyle of Bute. While they spent their time admiring the scenery, I was in the engine room!
Me too! For a period of about 10 years, from age 5, every year I went on the Rothesay trip, and I always spent most of the time being mesmerised by the engine.
We have never invented anything as magnificent as these old steam engines.
Always loved these old steam engines. No plastic covers, nothing that does not have a function. You can see everything thats going on, love it!
There is something hugely satisfying about seeing things revolving and hearing and sensing the throbbing power of the motion! The 'Ernslaw' on Lake Wakatipu is another of the same ilk but different machinery.
The paddle beats like the human heart ❤. That's why I like this boat. Not to fast like a lightning bolt but the way the wheel is spinning always make me felt a live.

This girl gearhead loves it! AUGH! Thank you. 😍
Glad you enjoyed it.
Awesome as can be.What a beautiful ,beautiful lady. Sweet memories of the oilers of my youth .I thank you all !
been on her many times, and as a retired engineer I can say there is nothing better than seeing this engine in action 🤓
Such a quiet engine room!
Waverley impressed me with her speed, a wonderful pulsing lope!
For generations of clyde passengers going to see the engines was a euphemism for going to the bar!
Engine room is cleaner than my kitchen !
I have been down to the Engine Room on a paddle Steamer. many times to watch the engines which drove the Paddles turning
thank you!!!! this is fascinating to watch so rare wonderful to see
I went on the Waverly from Newhaven many years ago with my father. An amazing trip around the IoW despite loosing a playing card down the back of the seat and the worsening weather.
I love this design. Not only is it very efficient and powerful, but it's got a whole s***ton of moving parts, which I love.
And we can SEE everything. Which only adds to the appeal.
I’ve had the pleasure of working on this thing during my time as a marine engineer cadet
i could just fall asleep listening to the sound of that engine, utterly magnificent
Beautiful machine. Love to watch these. The power is incredible.
14 yrs work as motorman in foreign ship, this is my first time ay see this engine.

Fixed on one shaft.

a Beautiful sight
Anyone know what the round inserts are for, in the connecting rod guides?
I expect that they are just circular grooves to spread the oil out across the entire crosshead guide surface.
why don't gas engines use open pistons like this anymore? like of ships
Is there a reduction gear between the crankshaft and the paddle wheel on the outside of the vessel?
No, just one solid shaft (several sections bolted together). The crankshaft is mounted so that the drive shaft is just above the gunwhales.
This may be a stupid question......but are those stuffed animals (3 of them) riding on one of the beams of that engine?
Yes-they have all since been removed.
What about the speed it could generate,cannit be worthy selling in an ocean or confine only to river cruising? I am just asking.
