Ep 34. 3 0r 4 Bladed Propellers for a Narrowboat.
Vložit
- čas přidán 7. 09. 2024
- I noticed, when the engine was hoisted in, I had 4 blades on the propeller. So, does it matter, 3 or 4 bladed propellers for Narrowboats? Doing this research has made a difference in my understanding of propellers. It's a very complex business, so I need to make it easy and get the basics right.

Thanks for filming. Thanks for editing. Thanks for posting. It's been a slow burn but it's coming to life now. The prop stuff was interesting. Glad you couched it in layman's terms. Even I got it. Cheers Chris.
That’s good to hear Trev. Great start the the comment by the way. It has been a slow burn, you’re right. Just under 40 weeks for the launch, hopefully. There are builders who do it quicker and I’m sure Mark will continue to tweak work performances. I have learnt a lot myself in this process, not only about the build but the boat business. I’ll probably drip feed a few things in to future vlogs. Another slow burn.
Could not have said it better.
@@bobcollard11 thanks Rob.
Hi Chris
Propellor design and engine maintenance, you absolutely "Nailed" it. Janet and John would have been so proud of you. You covered the myriad of technical stuff involved in such an understandable manner, well done indeed.
Mel
Thanks Mel. Appreciate it.
Interesting, thanks for the Janet and John explanation regarding the prop, even I managed to understand it.. I think lol 🤔😅
I look back at that for guidance and unfortunately, it wasn’t one of my best but as you say, it sort of gets the message across. I never really knew what I was going to film when I went so it was very much off the cuff and learning as I went along. Janet and John works for me to understand it. Thanks Kath.
Hi Chris, Sorry I'm late this week as I was away until yesterday. Great to see the engine go in and the nice shiny prop, I used 4 blade as it does help reduce fuel consumption but gives you power if you need it... I see you forgot to duck ! I knew you would at some point lol. Hope your All well. Very Best Wishes Old Skipper Tim :)
Hi Tim. Engine’s in, and the 4 blade propeller which I must say was quite interesting to do a bit research on. The knock on my forehead was from the wheelie bin when the lid blew in the wind and caught the head - it fits the storyline though. At Crick yesterday, I found out the boat launch will the week of the 20th. Count down is on. Ground rush will be here soon. All’s well, thanks Tim.
Another title for this episode: The Turn of The Screw 😉. Love all the tech details, another brilliant vlog, Chris. Launch day looms
I've taken a tumble over the past few weeks as I don't want to succumb to the style of marketing that thumbnails request. Sensationalisation. It's all over the place from football headlines, to politics and now the Tube. I would rather this channel grow slower because people are interested in the content.
That said, I like you title. I've changed mine just now to evoke something different. The hard core of subscribers have already watched it. I know there is another 1K that will over the coming week but, I just want to test a theory. Giving in. Thanks Ice. Your support and comments are appreciated.
Best music i’we ever heard on a vlog.Chris your the man. All the best
Thanks. I’m genuinely pleased you like it. Fitting I felt for what’s going on. Not much need for that style later, although I’ll probably use it for engine services etc.
I've heard a lot of boaters talk on many aspects of boating. But I have never heard one speak on the, as you put it 'the dark art of propellers'. Absolutely wonderful stuff Chris. Cheers
Thanks Greg. I agree. It’s a topic, I think has been missed by most. It’s under the water and many have not had the access I have been fortunate to have had.
It is a bit of a dark art and in time I want to learn a bit more as I think the propeller is a very interesting bit of kit. Another vlog in a few months time.
Nice education on propellers! When you started explaining diameter with "this distance here..." I was like, "oh no, that's the radius," and then you continued, "then you double it," you got me 😂
Radius and diameter was always an issue. To be honest, I knew the propeller was 18” and the measurements was 9”. Even for me, the sums didn’t work out, so it was a bit of cuffing on camera as to what diameter was. Thanks for the comment J T.
Hi Chris,
That was compelling propelling …. Another fab and informative vlog. Fab that the engine is in. Boat looking gorgeous ⛴
Thanks as always Jackie.
Hi Chris. Smashing video once again - that great blend of well-researched and interesting info on propellers, along with latest news and views of the boat, with a dash of Chris Mears' humour thrown in - we love it ! Interior of boat looks elegant and classy - what a great combination the woods chosen are with that fab Prussian Blue. Just dying to see the colour scheme for the exterior now and to see it in the water. Thanks again for all the sharing, it's really very much appreciated. Take care. George and Trish. 😊
Thanks George & Trish. Although the boat should have been launched already, great things happen to those who wait. Patience is a virtue…… with a bit of luck.
Thanks for your support.
Hi. CHRIS , I am learning thd lesson of canal time, still wait on my boat to be finished, don't ask .... who knows when I will start my journey. Brilliant explanation on the propeller information.
BTW, BYSTILLWATERS IRIS has a 4 blade, and it's....... drum roll ..... a 24in propeller, ! Don't know the pitch or the bite. Bu I do know it is very maneuverable .
Great video again. We will speak soon . Have z good on. Colin.
I have rough plans to head down that way next year. Can you make mental notes of time and distance on the Thames and the K&A. I’ve heard it’s a bit difficult in places. Is that CZcams sensationalising or is it fact.
4 Blade prop. You wont know what a 3 blade prop is like but I do note my boat slows down quick. That is very useful. Keep in touch mate. Have a great week.
Hi Chris I will do that, my pleasure. I will have to remember, don't be shy to remind me. 😮
Man,,,we are enjoying your videos. My Mrs - Japanese - loves the colours of the interior and cannot wait to see the external colour. By the way,,,,she wants a new kitchen to match! We are looking forward to seeing you on your journey. As always thank you.
Sorry to be the bearer of a new kitchen design. Your wife has a good for colours. Sadly, it’s all the rage now apparently. The new grey.
Thank you both for your support. Thanks Ian.
Wonderful Chris, just loving this vlog series. Almost edge of the seat stuff. You take care and thank you.
As always Christine, it the comments and support that make it worth while. Without the viewers support, what’s the point. It’ll continue until, I’m a self made millionaire, too old, lost viewer, whichever comes first.
Really interesting vlog Chris. Never thought a propeller could make a difference. Learn something everyday. Woo can’t wait to see the colour suspense is nail biting.
Thanks Caroline. I'm looking forward to it too. I want be seeing the boat for nearly two weeks now, so it'll be interesting to see what has happened. I might get a launch date !
Thanks for stopping me for a chat. It was lovely seeing you both and I hope you enjoy your Weekend at Crick....and the whether holds!
It was great to meet you. Thank you for taking time to talk to us. We love your channel. Thank you again take care.
Love the colour blue. Looks really good. Great choice
Thanks Bradley. When the windows are in and the natural light shines in, it’ll look different. The camera doesn’t do it justice.
@@chrismears-inslowtime it will look even better. It goes so well against the wood too. Looking forward to seeing the outside colour!
Great vid Chris... so close now you can almost taste it! cant wait to see it!!
Almost. I’m so looking forward to the water bit and the colour and the windows, lights etc. Thanks mate.
Who would have thought there was so much technical thinking gone into a propeller....... As you say, antenna theory is a black art and as an amateur radio HAM and user of green radios for many years, I have been jiggered more than once, so forget prop maths. A great vlog Chris and its been a pleasure to follow this process from the beginning. Take care and looking forward to the next one. (Vlogging will be difficult from now on if you are to keep the colour a secret )lol
I believe we have discussed antenna theory or sorts before. I loved it. Pitting my mind against the conditions and types of antenna. Mostly I did well, but on those occasions that nothing happened, it was frustrating to say the least.
Propeller theory: I would like to learn more and as time goes by and experience gained, I'll get the chance.
Thanks for your support along the journey. A bit slow at times but, with about a month to go before I'm out on the 'cut'. Can't wait.
Oh the colour. I can't believe people are looking for reflections on the side wall ! Funny. I like their tenacity. Keeping it a secret now means I can't film directly outside and I'll also need to be mindful of the inside too. The portholes and windows will give it away. May need to reveal sooner than later.
Thanks Chris
Another great video and well explained about the prop.
I'm also loving the colour😄👍
Dean. What colour? I haven’t let it slip, have I
😂 No Chris but I think I saw a reflection in one part of the video people will have to watch the video again👍
@@deanconnolly100 someone said the same thing. I never noticed it while editing and….after another look, there is a reflection of something, but it doesn’t give away the colour…much. Need to be more careful in future. I also result is what matters
The (boat) whatever name it is looks fantastic but credit and some serious kudos to everyone involved in the build looking forward to the launch looking like fair weather for the maiden voyage !
Thanks Tim. Name is being painted on as we speak...type. Good weather, good builders, so what could go wrong. Nothing hopefully.
Very interesting…thanks Chris
Thanks Mick.
Excellent content... your vlogs are always enjoyable. Thank you.
Thanks Michael. I very much appreciate your time and perseverance. Thank you.
@@chrismears-inslowtime Not sure how you got Michael out of Andrew... was that a test? I do read all of the comments. Thank you for taking the time to reply. BTW, I have been called worse names for sure...
@@andrewwheeler2599 nor do I. I’m so sorry Andrew.
@@chrismears-inslowtime Thank you, but no reason to feel sorry.
good info on the props
Thank you.
All this stuff about props is all good stuff to know. I thought about changing the impeller on my ski to a Solas prop I got a good deal on at a show a while back, but it may be too much impeller for the stock motor. Need to check the numbers. Your boat is coming along nice, not long before you'll be out on the canal network checking out different places.
Hi Paul. I found the propeller surprisingly interesting. Such a small thing that has a profound affect. 🤔
Science and engineering is important. It’s a shame I’ve only just started to become interested.
Nice seeing the engine going in and you’ll always need stopping power for the crash bang wallop‘s that will happen😂👍👍👍👍did I say what a picture 😂
I like the Wide beam been lowered in place that looks nice 👌 you’ll soon be out there 👍👍👍
It'll be like the first time I scratched my alloys on the car, which still only has one one scratched, I almost cried. If I bump the boat, not a kiss, but a proper bump, I'll be distraught.
That wide beam should be nice. It's almost worth The Fit Out Pontoon continuing the story. Thanks Tom.
Hi Chris, watched you from day 1 at Graham Reeves, enjoyed every one, looking forward to launch day & hope
to spot you at Crich on Friday.
Thanks Michael. I really appreciate your staying power. Many have fallen along the wayside. Please say hello at Crick. Pleased you still enjoy it.
Thanks for stopping me at Crick for a chat. While it was brief, I do appreciate it. I hope you had a good day. Enjoy the 'PlatsJube'.
"thrust is something i learnt about 18 years ago"...... i was wondering which way you were going, but well recovered!!!
I learnt about that sort of thrust 40 years ago, although a little older before it was put to use. I hope you and the boat are doing well.
Hi Chris. The brass spinning thingy... Interesting!! I'm sure that monster 50 HP engine will marry just fine with your prop, your guys at fitout pontoon know exactly what they are doing! The end in sight now matey - exciting stuff!!!
Thanks mate. See you Friday!
@@chrismears-inslowtime Will do - I will track you down!!! Glenn.
@@losendos194 thanks Glenn. I shouldn’t be to hard to find.
Thanks for the chat today Glenn. It was nice to have eventually met up with you in person. Looking forward to catching up on the Cut someday very soon.
@@chrismears-inslowtime Great to meet you yesterday Chris, I very much enjoyed our chat at a very busy Crick show! Not sure what happened with the phone number exchange, however I suspect signal problems in the Crick area. Hopefully we can sort before the big day at Redhill... Stay safe my friend.
Don’t forget paddle wheel effect…. I’d go 4 blade any day, not going water skiing. (Now there’s a thought 😂) . Shame you can’t do a live/same boat comparison vibration and 0-4 knots. Love the paint tease. Not long now.
Had to look that up. Didn’t know that, thanks. I agree with the contrast with a 3 blade. Il sure one day I’ll experience it on another boat. Thanks Steve.
Another cracking video, Chris. I agree with Christine below “Almost edge of the seat stuff”.
When does the bow-thruster system get installed?
Bow Thruster is in. Thanks for the jog of memory. I need to be briefed on that. Trouble is, it’s underneath the bow which I can’t get to as I’m not allowed to stand on the paint until I’ve taken charge of the boat. I’ll have to do a vlog on that later.
Thanks as always Martin.
Viewer #2 tonight.
I've read somewhere that a 4-bladed prop will deliver smoother transmission of power, which apparently is one of the reasons a lot of ocean liners were designed with them.
Regarding engine maintenance, I wonder if synthetic oil would get you more hours between servicing? It's more pricey, but fewer oil changes would likely be a saving. Maybe something to research after the engine is off warranty.
There's nothing quite like a pristine engine bay.
Suggestion for homey touches. If there is room for a couple of plants, make sure they are useful ones. An aloe vera is a great thing to have for cuts, burns, and any kind of skin irritation. A spider plant will do a good job of cleaning the air, and will survive just fine in low light. For the summer time, a pot of basil can add lots of flavour to whatever you're cooking. Or substitute any other kind of herb. Those can live outside, but don't usually overwinter well. Just a thought.
Can't wait to see what colour was being applied on the outside.
You’re right Peter. Subs have more as it produces less noise and the bigger they are the less power is required to push the boat through the water. I’m sure it’s different now, but, that was for propeller designed boats.
Don’t know on the oil, I’ll find out but, even if I keep to the suggested time table, I might on the first use synthetic oil.
Great tips on the plant though. I wonder if they will be able to live in home made compost? Put that to good use. Thanks Peter.
Hi Chris. Your 4-blade prop will give you more power (thrust) which will assist in maneuvering the boat in windy conditions. You can never have too much power- speed is not that important on a narrowboat.
Thanks Tom. Top advice. I’m going to try to inform better as I go on. Power doesn’t equal speed on a boat. It equals thrust and ability to manoeuvre. Speed equals wrong lifestyle.
Chris,
Reading some of the comments of your very loyal set of followers, I wondered if there might be the opportunity for those who live close enough, and who have the time, to come, watch and celebrate the launch of the boat? But I’ll net you’ve already thought of that.
I need to understand what the procedure will be. I have thought about it and some will be there I’m sure. If I invite people, I feel I have a duty to host. That day, I imagine will be fraught with all sorts of stuff, most of which is outside my control.
I’ll be spending it filming and I’ll enjoy the day through the edit after.
Like the sentiment Martin and thanks for the prompt. Your absolutely right about a set of loyal subscribers. Like yourself of course who has my best interests at heart.
@@chrismears-inslowtime You’re dead right, Chris; I hadn’t thought it through.
Morning Sir,
Did you mention willy wave and then nearly fall over? that made me smile
How many chickens are sacrificed in the dark art of the prop? them engine service time are amazing, what was it compared to the original Beta marine you was going to have? lucky escape maybe. Heart of the boat is in which is absolutely fantastic
As always Hope Max is having a good week and treatment plan is going well! does he like the fact his pops is becoming a YT star? :)
Your right on all counts. I hate the forums where people are trying to outplay someone’s opinion. I bet on a face to face basis, it would be so hostile. I think I’m right, haven’t looked it up, but 200 hrs for an engine service. I dodged a bullet there didn’t I.
Max is at home now. At least for a bit. Going to see him this weekend. Thanks as always for your support and thoughts about Max.
As for me being a YT start….long way to go.
Hi Chris,regarding WD40 on turn on thing, I would use 3in1 spray. WD40 will clean out the grease in turn on thing and make it worse.
That’s interesting and useful gen. Thanks Martin.
The boat (Swanmead) is a deep, dark green! What do I win?
You get a trip on it ……..but here’s the game, you need to find me first. Oh and travel 1000s of mlles. For you, I’ll let you steer it, make the tea, polish the brass and if you’re really good, empty the toilet. You can have the full boat experience. What’d ya think?
@@chrismears-inslowtime Sounds like a great deal to me but will only empty the toilet if you explain the prop pitch diameter horse power thingy again without reading it.
Was an interesting episode mate
@@TaupoHotspur deal. Now I’ve edited the video, I’ve learnt it.
Big build up to paint job ……and we never got to see it!!!!!
Hi Glenn. You will eventually, in about 2 gusting 3 weeks. Thanks for your patience. I’m sure it’ll be worth it.
At the Beer Ten outside Chris 3.22pm
Thanks for a great chat Nick. Hope to see you both on the cut sometime soon.
@@chrismears-inslowtime nice to meet you Chris looking forward to the reveal and laughing of your boat. You will love it. 👍🏼
Ps still waiting for the David Bowie tribute 😂😂😎
I’m a bit under pressure mate. There’s a Starman waiting in the sky, is that tribute enough !
@@chrismears-inslowtime 😂
Neither acceleration or top speed are particularly critical when you are piloting a narrow boat in my limited experience, Chris. One further comment - the reflective insulation inside your boat's current residence may have given a clue to the paint colour. If I'm right, it looks to be a good choice.
Launch day draws ever closer...... :)
Sharp eyed people. I think you may just about see a faint glimmer or something. I didn’t notice that throughout the whole edit. Not sure you can make out the colour as only the roof was done. Need to be more careful.
Agreed with the speed. I’ll not be pushing mine on a regular basis, although it does say to push the engine to full revs every 50 hrs for 15 mins. Hmmmm.
If you think the paint looks great now wait until the rest of the coats are put on and the depth of colour comes through. 👍🏼looking forward to the Colour reveal.👍🏼
Thanks Nick. The colour on the handrail looks amazing but it’s masked off but the bow trimmings are done in the same colour. I just can’t wait for the finished boat and get out there. Not long now….hopefully. 🤞
@@chrismears-inslowtime we are checking in with our boat builder while at Crick Friday-Saturday 👍🏼
@@nickevans1698 I’ll be there on Friday. If you’re about give me shout.
@@chrismears-inslowtime will do. I’ll keep a look out for the landing pad 👍🏼😎
Just don’t wear a hat 👍🏼
I'm surprised these guys have you so much access to their workshop.
I don’t think any other business would have allowed it. They are proud of their work. There have been times when H&S common sense has precluded me from filming, mainly paint stuff but generally, it’s wood worky stuff. It shows attention to detail which is the principle reason I chose them to fit out the boat. Thanks for the comment.
@@chrismears-inslowtime I'm a cabinet maker in Aust, who hopes to one day own a boat myself. So I have thoroughly enjoyed the whole thinking and building process of these videos.
ps I'm bald too and constantly cut and scrape my scalp. must wear a hat
@@pholland6643 hat…..good point. Good luck on your boaty dream. I’ll hopefully let you know what it’s like. Good skill to have if you’re going to do a DIY fit out.
Ya shoulda gone with a super-old-skool "side-wheel paddle" set-up. Of course you'd probably have ducks & geese constantly clogging it up - and you wouldn't fit in most canals due to the extra width. On second thought it's a stupid idea. Don't listen to me - I'm an idiot. The engine looks complicated but you'll probably be swapping it out down the road for an electric one as the world moves away from fossil fuels. Keep vlogging - we're all emotionally-invested!
That side wheel paddle affair will need an army of people to manage and just think of the cancel culture I would have to endure. Steam power is very much in the history book era now. Shame. Even my diesel car is. 57 mpg as an average over 77 hours of travel. Not sure how many cars today can get that. I only use it for long journeys driving at 60, like Miss Daisy.
Swapping the engine out for an electric. Won't be anytime soon. In fact I'm not sure if I could retro fit one. The canals need to move into the 21st century. All those who are going hybrid or full electric, will not be doing what I plan to do; Continuous cruising. If they do, they'll have a generator which will run on diesel. Ok it'll use less but, it's still not all that eco. I wonder if an all-electric boater will end up becoming a vlogger. It'll be interesting to get a true viewpoint. Not an Instagram life. That could change or influence CRT policy on eco-boats.
Lots of boat stuff to talk about on the 'Cut'. Thanks Si.
It’s always good to learn one new thing every day Chris and I didn’t know there was so much to think about for a prop on a narrow boat! Launch day must be getting close now……are you planning on cruising away on the big day or pottering around until you feel comfortable to make the leap from dry land to living on the water?
I’m not so sure many people know about propellers. I’m sure if they did, it would have been mentioned in detail by other vloggers before me. There is a lot of science and I covered propellers 101. There are terms such as cavitation and ventilation, but that would have made the video too in-depth. I may cover that on the cut.
The big day. The plan is to go up the Erewash canal as a starter, to get used to the boat. A quiet canal, generally. Then, I’ll drive it down the Grand Union to the Smoke. I think that should offer me sufficient experience by the time I get there. Thereafter, the worlds my oyster, so long as it’s in the Uk ! Thanks Darren.
We walk a section of the Grand Union most days between Watford and Croxley Green - I’ll be sure to keep an eye out for you cruising past 👍🏻
@@darrenking4715 it’ll be great to have a chat and I’ll make you a cuppa. As you notice I’m getting close, please remind me.
Look forward to it.
I just serviced our barrus 45 after 50hrs & did the gearbox at the same time , my thought behind this was that the gear box isn't engaged all the time only about half
Interesting point Adie. I’m probably going to stick to the guide. Trouble with vlogging, it catches you out if you don’t. I have some very switched on people who will expect me to keep to the schedule. They keep me on my toes for all the right reasons. There must be a reason in my mind too though mate. In todays world, unnecessary use of oil would be frowned upon. Also, 350 hrs for oil change. I was expecting 200 hrs, which is what I’ve heard from the Tube. That is a proper gift. I get your reasoning and efficiency though.
Are you pleased with it.
@@chrismears-inslowtime yes mate love it , we have a hospital silencer as well & always get asked if our boat is electric as it’s so quiet.
Only thing I get is a bit of “prop sing” but I’m told that wears off
@@agfbuildingI couldn’t afford the hospital silencer. You’re the second person to state that. ‘Big’ commented last week stating exactly that. I’ll have to get used to an engine noise. Never mind.
@@chrismears-inslowtime tbh the Barrus is very quiet anyway, really enjoying your vids awesome stuff 👍
@@agfbuilding good to hear Adie; or not
Hey Chris,, uhhh is the MDF they use the outdoor waterproffed kind???
Great question Russell. Condensation is the biggest killer of a boat. The owner of The Fit Out Pontoon lives on a boat and has for a few decades. He realised condensation forms and then gets into the wood and all surfaces. You’ll notice all wood is melamine MDF and even the cut side has been edged and rounded so assist in water running off. So, if condensation forms and it’s not been noticed for a while, it’ll ‘pool’ and not get into the wood. More expensive, but the boat should look new in 20 years (or longer). Hope that answers it. Thanks for the comment.
Hi another good vlog just thought I might say that know somebody has brought up using MDF you will probably get loads of comments from people that think this is a bad thing to use their best arguments are normally if it gets wet it falls to bits my answer to these people is if it gets wet enough to ruin it that means my boat is sitting on the bottom and I have more to worry about then a bit of wet MDF I have always used MDF for all my fit outs and never had a problem my present boat is now 16YRS old and all the wood work looks as good as when first fitted
@@bigKDL thanks for the comment. Many have critiqued the type of wood and for the reasons you have stated. I don’t know, how many of those critics have a boat or build boats. I trust Mark and the reasons why he does what he does. Clearly, you as a boat builder have the same view point. Thanks for the support.
The intro only put me off . Bad music. Bad editting. Poor craftmanship. Followed by man moaning a lot.
Thanks for the comment. Well I was taught if you don’t have anything good to say, don’t say it. You don’t like the music, you don’t like my editing and I’m not sure who was moaning. Why watch it? I don’t think you can talk about the craftsmanship as you’re not there. I’d like to or watch one of your videos so I can learn about how to do it. Please share a link that draws me to your professionalism and vids.
