For all of us Nautical Nerds you have taken NautiStyles to a whole new dimension. I applaud you for not filming this as a "fluff piece". Absolutely fascinating post, especially knowing these Props go on Submarines. Well done. Please keep it going. Whenever you go down in the Engine Room, I could listen to you all day. Great work!
@@NautiStyles Truly- You have now placed NautiStyles so far above the other boating sites. The most refreshing part, your enthusiasm. You truly love boating. Every time I contemplate losing my life savings again to a boat, borrowing a scene from the Godfather 2: "Every time I want out...They draw me back in!",
Very well made episode. I was a commercial ship surveyor for almost 40 years studying and surveying all aspects of ship design and construction in shipyards all over the world. Been retired almost ten years now and had never seen or heard of interceptor strips. Fascinating, a simple idea that was previously un-thought of. I have been watching Sharrow prop design for 2 or 3 years now and glad to see them in partnership with Veem producing usable sized marine props. Good job Victoria and Rico. I have really enjoyed watching your excitement and level of curiosity as you go through the build process on your own Bering.
Unbelievable that I can watch a technical video like this for over an hour. You guys are brilliant in your presentation techniques. I'm fifth generation Australian and my partner is first generation having migrated from Korcula, Croatia when 1 year old and I can't tell you how proud I feel watching this video.
NautiStyles getting into some top technical marine journalism. You guys rock. With your up-beat, cheery personalities, you must fit right in with the Aussies.
I worked in the aluminum industry for 20 years, so this was fun to see! Then the pride was evident in these guys. As usual, a great episode and greetings from Sweden!
WOW, that’s got to be one of the best videos I’ve seen from NautiStyles. Thank you Veem Marine for allowing NautiStyles to make this video within your factory in W.A.
I love videos on how things are made. The idea that people are still improving on centuries and millenia of reshaping the world to our needs is amazing.
The pitch strips are brilliant. I immediately grasped the importance and am so impressed that someone came up with this exciting advance in hydrodynamics. Thank you thank you thank you
Agreed, especially the way they can be changed in the field if needed. I imagine if they were being made for a customer wanting a CONSISTENT application (military for example) they could actually mold the "interceptor" into the alloy.
Those pitch strips look like water versions of the Gurney strips used on race cars. They were named after Dan Gurney the world famous race driver who used them on the back edge of wings and even car bodies, to shift the airflow up and over the back of the wing or body, to break up the suction that normally happens when air flows immediately over the back. On street cars, this is what causes all that dust and dirt to accumulate so quickly on the back of your car. It reduced drag and allowed cars to go faster.
Giving 'How it's Made" a good challenge. And yes, I had never heard or seen the Interceptor strips, yet the concept intuitively is brilliant. You can experience this in nature. In Cape Town the massive Table Mountain range creates a standing wave of wind flow yet at the base the wind is not blowing as the air holds against the mountain but the flow going over the top stacks up in layers. A world record glider altitude was set by hanging in the standing wave and letting it do the work. I can see this effect in water in my mind with that simple strip creating the V to combat swirling cavitation turbulence. Amazing ! Great Video.
Automatic trim on powerboats has been used through the use of interceptors on the stern possibly 10 years now. So it's only reasonable to think that somebody would come up with the idea of putting it on the trailing edge of a propeller for exactly the same reasons.
If you want to know what's happening in the marine world, you can't find a better team than Victoria & Rico. This was another fascinating, EXCITING video showcasing propellers and the innovative techniques used to make them. I've never really thought about props before but this video opened up a whole new world. Keep them coming!!!!
Having spent most of my adult life in Marine Engineering sales environment and retired some 15 years ago, this technology is now far more advanced than I could have imagined. Those automated machining processes are amazing. The micron tolerances they mentioned simply wasn’t achievable in my day. Fascinating and very interesting. Thanks for sharing guys
Excellent video, Victoria and Bart you're a great team and did our Aussie company justice. Love the enthusiasm and appreciation of the fantastic efforts and developments of all those at VEEM.
Interceptor strip tech is amazing. And I also never heard about it before. That such a little thing can have such a big effect is quite something. Great video and you guys asked so many good questions. Hats off to you 🤗
This is such an interesting process. VEEM is very impressive and I would definitely require their products (propellers & Gyros) to be installed on any and all vessels that I will have built in the future. First Class Quality. This has been one of your best interviews.
That plastic strip for the props is very similar to a "Gurney Flap." In '71, former race car driver Dan Gurney had a driver named Bobby Unser, who was complaining that the rear wheels on his car didn't have enough traction, and Dan remembered some experiments he and his buddies had done in the '50s, so he literally bolted a piece of angle iron to the top of the rear wing on Bobby's car. He immediately got far superior traction. I love that this tech is being applied to propellers.
@@michiganengineer8621 Yeah, the race stewards most have felt that a piece of steel angle iron attached to an easily breakable part of a car was a bit of a safety risk. After hat they made it part of the wings. That's why so many race cars including NASCARs had ducktails for decades. It's pretty cool. Water is so freaking dense it's remarkable how little a raise it needs to be to have a profound effect. I love hydrodynamics.
I loved this!!!!!!! The importance of the propeller is so underrated. The propeller is the point of transition from drive, thrust, horsepower ... into thrust, which propells the boat/yacht. Sooooooooooo important.
To me, this goes back to the 1970s when I was a Boy Scout canoeing in the Boundary Waters (US/Canada). I was pretty strong and my little paddle cavitated which I realized was wasted energy. Now, many canoe paddles have twice the surface area vs. the lowest common denominator.
This great! I mentioned Sharrow props a couple times on your videos over the last year and here they are. It's really nice to see that they're not "vapor ware". I'm pretty sure VEEM partnering means they are on to something special. Thanks!
I'm a retired metallurgist who worked in metal industry for almost 40 years and in various metal forming processes. It still fascinate me watching this video like a kid in the candies store!!!! Thanks....
I love it all and I am always fascinated with new technology nd creating new ways to make things better or just create new things....This all brings joy and passion to an everyday lifestyle not a job because I enjoy it so much that it's not work and there should be more employees in the world feeling this way but unfortunately they don't. This company from top to bottom has made it enjoyable for all it's employees to be proud to show up everyday nd proud of the end results of all they've created and accomplished. It would be fantastic if that exact company was here in america because I would have been at that company for about 28/30 yrs already nd still would do it for another 10yrs maybe more b4 retirement........Great video as always nd I could imagine being there with smiles looking nd learning about it all...thank u
Love your manufacturing series. It is great to see the actual tech that goes into boating. Most exciting is the partnership with Sharrow & Veem. Toroidal propellers are the future, the problem is/was mass production. If Veem can make them this is huge. Hope you get to install toroidal on the new boat. The fuel savings would pay for the upgrade and your exposure would go a long way into getting this tech out. A true win win.
I have pre ordered a pair of Sharrow by VEEM propellers for my inboard boat. I'm so excited to get them fitted. The mechanic at the boat yard in MDR just put a pair on some outboards and the customer LOVES them. Great video. Thank you. Miss your videos from So Cal though.
You guys are bringing us the next level of RU-vid videos. Love seeing these passionate craftsman talking about their job and manufacturing proces. When your Bering is finished I hope you get a wonderful break onboard. It has been a lot of travel for you but holy high quality genuine videos you bring us. Thank you.
Hands down one of the best videos ever on RU-vid. I will watch this probably 2-3 times in the months to come fascinating. The prop is almost as important as the engine for the performance of your boat/ship. Thank you for delivering such exceptional content.
Veem Interceptor props have been available since the early 2000's I believe. Most sport fishing boats were sold with 3 blade props, this was for sales purposes. A lightly loaded boat with 1/8th fuel, no tower, and a slick bottom planed out nicely with a great top end. The boat you receive loaded with gear, fuel + tower and bottom paint turns out to be a real dog. Time for new props on a new boat, your endless journey to the boatyard begins, welcome to the world of boating!!!!!!!! Every marine product supplier has their eye on you and would love to get to know you and lighten your wallet. But hell, you're on the water (at least some of the time) and that's what it's all about.
I think I have read of the interceptors some time ago as a concept, but I had forgotten about them. It's great to see that a great idea is being put to practical use, and I am REALLY interested to see how efficient the tipless propellers are with the interceptors. Thanks for the video!
I have watched dozens of your videos over the years and have loved them all! But this even at over an hour long was SSSOOO GOOD! There is a whole generation of younger people that should have to watch this. So great to see the two guys leading the tour so into their job and proud of their company!
WOW, FANTASTIC EPISODE. I NEVER HEARD OF THE INTERCEPTOR STRIP TECH. I'M A BIG FAN OF SHARROW PROPS AND PARTNERING WITH VEEM IS BRILLIANT! GREAT EPISODE.
I have been watching your channel for some time now from down under, and enjoyed everyone of them, but this one was absolutely fantastic. I could not take my eyes off the computer. I'm a retired turbine/instrument tech and in some instances when watching tech presentations I find them as boring as watching grass grow, this was great, thanks.
Fascinating video! combines two of my favorites... Manufacturing and boats. I first saw the inside of a foundry 54 years ago. This one is much cleaner and obviously much safer than the first one I saw. After spending 40+ years in Manufacturing (piano frames, architectural windows, metal casework, etc.) and IT (ERP systems), it was great to see all the old and new technology coming together.
I have one very minor request. Please take another 5 years to finish your yacht. These episodes where you do factory tours of the parts and equipment comprising your new boat are fascinating. No one else is doing this and the skills and tech acumen involved in their production is laudable. Don’t stop 😎
Fantastic episode. Great to highlight such hi-tech design, engineering and manufacturing. Fascinating for those of us who are 8 years old at heart. Thank you.
That was an exceptionally interesting tour. Time well spent. Can’t begin to tell you how impressed I was, listening to the creator of the Interceptor strip describe the development process. Thank you, VEEM, Shallow and NautiStyles.
Thanks for making this video. The enormity of the products manufactured there was so eye opening for me. Also thanks to Veem for allowing you and us access to there process. Cheers to you both.
This video is an hour and five minutes. I just made myself late for a meeting because I couldn't stop watching it! Excellent stuff! Fantastic content, - as usual! Thanks!
Thank you so very much for taking the time to tour the facility. Quite enjoyable and educational. And, as requested, I did not know anything about the interceptors. That is incredible. With this, one could remodel full sections of the boat (possibly changing the weight or profile) and, rather than have to order new props, simply take 15 minutes out of the day to change out a few strips. Not to mention, it's another reason to get in the water...
I had never heard of their “interceptor strips,” so this was very educational. My yacht is a 1964 Chris-Craft, so when I need to replace my props, I’ll be ordering a set of Conquests! 🤩
I knew almost nothing about any of this. I am totally geeking out on this video. And will rewatch later today. No telling how much I missed the first time.😊
Wow. This volume😮 of comment response really 😮shows the quality of your viewers! Top notch people obviously and as an ad man myself such a resource is priceless.
Wow! Great prop tour… as engineering student studied induced prop cavitations. Professor said “never will quality of metal material demand meet production requirements for raising cavatational speeds”. 50 years later and you’ve shown how they did it! Amazing.
This video, along with the Riviera factory tour, is fantastic. Your combination of actual real world marine expertise and easy back and forth charm is hugely valuable to your brand.
Answer to your question, yes I have seen and repaired these props in the Netherlands. Too bad we couldn't see the milling and finishing, that's the REAL craftsmanship I like to see. I understand that it is a company secret, we have the same thing in our propeller repair workshop. The fact is that due to the high technological developments in CNC and 3D of exotic models, repairs are lagging behind, you will never get damaged propellers as good as new, but we do try.😊 thank you for your wonderful contribution to show us.
From an x boatbuilder keen fisherman with my own boat living 400km north of Perth never even seen such design taken to that level bloody impressive.One thing when you start another process of manufacturing you will always create another problem which you have to overcome and this company is at the forefront of this process.proud to be a west Ozzie 😊
Quieter propellers for submarines mean it makes it much harder for an enemy sub or surface warship to find and attack it. Obviously, other factors go into reduction of noise on subs, but quieter propellers is a must.
What a facility! Thanks to you for the channel and to the people at the facility for such an open and interesting walk through. One of the best videos I’ve ever seen RU-vid. Thank you.
As a West Aussie I can let you know the secret and that is that we are so isolated from everyone else that nobody told us we couldn’t do everything that we wanted to so we just went ahead and did it.
Glad you got to come to my home just love Perth, I have known about veem for a long time and have seen lots of their work over the years but like you I had not heard of inceptor-strips what a fantastic invention make me proud to be a west Aussie 🇦🇺
I loved watching this. i am from Australia and i am not surprised about the amount of ingenuity coming from Australia. There has been so many technological advances come from here over the past 50 years.
Haven’t heard of the interceptor strips, but I was ahead of my time on other things. I think it was a year ago, or so, that I asked if you might get Sharrow props on your boat(toroidal design). They weren’t making them that big at the time, but they are now. This whole episode was such a geek zone for me.
Thank you. That was a great programme NautiGuys. Well done Victoria for fronting such a technical episode with the same aplomb that you guide us around all the storage solutions in your yacht reviews. Fascinating stuff. It would be interesting to see some independent test data on Sharrow Propellers and also hear VEEM Props view on the Sharrow prop. If they’re manufacturing them I presume they have run their own tests. My recollection is from watching another review of them that the Sharrow props aren’t so beneficial for displacement vessels that are running at prop speeds below 2,000 rpm, and I presume that is because less energy is lost due to reduced tip vortices at lower speeds?
This was the first time I had ever heard or seen the plastic strips over 50 and I learned something new great episode. I was with Rico could not get enough of the pouring of the metal.
The Interceptor strip is a modification of the stall strips that are used in aeronautics on the top surface of an airplane wing to affect the flow over the wing at high angles of attack. The stall strip changes the turbulent flow to laminar flow and lowers the stall speed. You can see them on many homebuilt airplanes where the builder is allowed to experiment unlike the FAA designated planes that must conform to rigid standards of years gone by. Technology is changing so rapidly that the standards people can hardly keep up. Loved this video, very informative.
As a diesel tech I can seriously appreciate the tool box stickers at 41:20. I appreciate this company allows the guys a bit of humor and self expression.
This is what youtube should be all about, well made videos with smart people asking smart people intelligent questions . Well done guys , there is hope yet for the human race.
