Making our Rudder - PART 2

- The second half of our composite rudder project.
As most of you already know, we built two new rudder blades for Paikea when we did our refit in Valencia, Spain in 2020. As the boat was on a cradle that was quite low to the ground, we were unable to remove the rudder stocks easily from the boat. There simply wasn't enough room to pull the stocks out before they hit the ground. Instead, we made the decision to keep the existing stocks in place and build new rudder blades to fit. This compromise ended up costing us dearly as we lost one of our new rudders halfway through our Atlantic Crossing. The rudder shaft failed and snapped off leaving us to sail the remaining 800nm with only one rudder.
In the next year and a half, we sailed up and down the Caribbean Windward Island chain with only one rudder. We needed to find the time, money, and materials in order to design and make replacement ones. Shayne loves his data and had been collecting as much as he could in order to design a more efficient rudder for Paikea. He designed carbon fibre rudder stocks, which we got C-tech in New Zealand to build and send to us in Antigua. Once we had sourced most of the materials we required for the job in Martinique, we were able to commence building the rudders.
In our last video, you saw how we made the new rudder blank. Now it's time to laminate and consolidate. Here's Part 2 of building our composite chain plates.

Aussie’s just aren’t afraid to give it the onion! Just whip up some of the most crucial parts of the boat and send an ocean by next week Thursday! Love the Aussie spirit. Must be a bad ass to be on the racing team. Congratulations and safe travels from Montana USA
🤣🤣 May have bitten off a bit more than we could chew 🤣 Got there in the end 😅
Thanks for well wishes on Cup campaign. These AC boats are wicked 😁
It is PROFESSIONAL...period. Lol. Interesting rudder shape that you came up with during your research and development. I get so many design concepts from your videos. I am looking forward to some updates on training with the America's Cup team. As I make plans on Swift (1991 Catana 48), I am using your amazing mods and repairs as a guide. Thank you for sharing.
I take 3 hours to put in a new through hull on dry land, and it wasn't pretty. Then I watch you guys install a new rudder bearing and DIY carbon rudder using a snorkel, in the water. Impressive work.
Thanks 😅😅 not an ideal situation but we got it done.
It's always all about the cool :D
🤣 always
A master of the arts the old barnacle
Cheers mate
Very impressive! Good job!
Love the work you perform. Inspires me to do better work on my own boat.
So glad you have a life rope for your cat.
Beautiful
Great job, would love to see/hear more about how you made the tiller arm and its attachment. Thanks for the content!
That looks way faster. Did the port hull get to Europe first? We've missed you guys online. Big congrats on the AC job. I'll forgive you for leaving multihulls for this bc who needs more hulls when it's all flying anyway? Hoping you can share little tech tidbits along the way of the next couple years. I was making carbon chain plates yesterday for a farrier tri rehab and during wet out was wondering what the Barnacles were up to ;)
Nice to know we were missed! We were busy testing asymmetric rudders on long ocean passages 😅
Really happy with the new rudder. Shayne was super stressed the orcas were going to eat it going past Gib. We need to make the other one now and start pulling Paikea apart ready for the next phase of upgrades.
What an amazing experience your sons are getting! Thanks for sharing the process.
Great episode, the struggle is real.
😅 got it done in the end!
Bloody genius but speak a bit more about what you are doing ya bastard. Thank goodness for your Missus otherwise it would be like a silent movie. Oh yes congrats about the job although I don’t know how surprised I am really.
🤣 it's hard to get him to talk to the camera some days! I got a good video with talking coming up next week for ya ☺️
@@youngbarnacles Well it’s always a pleasure watching your video’s you are both so very competent and watching Shane is like watching an artist. I mean that too he’s so bloody good with Carbon but you can tell him from me that he would be crap on the stage unless it was a mime of course 😃
Amazing how little contact there is between the skin and the shaft. Obviously, you feel that this is strong enough. Is this from previous experience?
There is some fundamental composite engineering that confirms this will work. Also 20+ years experience in the composites industry and sailing gives me the confidence to say this is the correct approach. Having just crossed the Atlantic Ocean with this rudder is another testament to the theories and experiences we've already had.
great job
I've been re-watching this series, but I can't find the info about the weight. What was the final weight of the rudder, axle and tiller arm?
Hi, with respect to your templates. Back in the 80’s I was designing and building a keel and rudder for a Martin 29 sloop. The research I found indicated that the trailing edge should not be a knife edge but should have a flat 5% of the maximum chord thickness. The theory was that drag created by the flat edge was less than the drag created by the turbulence of the high pressure flow wrapping around to the low pressure side and causing flow separation on the low pressure side of the foil. Im interested in your thoughts on this? I really enjoyed the rudder build videos as I’m in the process of building an Avalon 8.2 Trimaran (Similar spec to the F82R.) and I am planning on building foam core rudders and a foam core dagger board. Thanks for taking the time to make the videos and post them. I tried videoing some of my build and it is very difficult to do right.
Cheers

Sounds like you've got a cool project or two going on. Did you have a look at our vid on inspecting the hulls and our thoughts on rudder design? ua-cam.com/video/tdr2Zl2rKAQ/v-deo.html
We have a discussion forum on our website which may be of interest to you
www.youngbarnacles.com
Dying to know what you used to glue that bearing under water to the hull? Surface prep as well?
Great vid as always an inspiration making a good old cat into a great old cat! Is what your doing achievable for a non pro laminator/Sailmaker with an older cat and limited budget?
The most important thing to start with is a good performing and well built older cat. If you have the patience to learn the rest then anything is achievable

Hi great video where did you get your carbon rudder stock
It was custom built to our specifications by C-Tech New Zealand
So... I saw you laminate the carbon onto the rudder prior to vac bagging but then the finished rudder had only biaxial glass. what happened?
No carbon on the rudder. You would have seen black breather felt used in vacuum bag process
AH that explains it! thanks
@@youngbarnacles
😊
Why not carbon around the rudder? Also love your vids, happy your back
Carbon would have been nice but I didn't have enough for the rudder too 🤣
