Mast steps! - ep84 Project SeaCamel

[@rochus_wagner]

😲I haven't heard Hungarians speaking for 10 minutes, the experience is still fresh. I can compare the two languages, and I've come to the conclusion that these two languages, Hungarian and Finnish, have nothing to do with each other. This was the big surprise of my day! Congratulations on your work, you're doing great, keep it up!👏

[@ArcticSeaCamel]

Hungarian is same language family yes. But very very different from Finnish. The closest language relative is Estonian. 🇪🇪

[@rochus_wagner]

@@ArcticSeaCamel Yes, I think so too. You speak such a beautiful language. I was so happy to hear you include your native language in your video. It brought you even closer to us. Thank you!🙏

[@davidtaylor5394]

what an amazing character| Love your site and follow it with great enjoyment. So looking forward to the finished product

[@ArcticSeaCamel]

Thanks so much!

[@pgsharrow3714]

I would suggest you get some of "Cold-Galv" paint to touch up any exposed Steel. Equals 85% of hot dip. I have used it under sever conditions.

[@Finn-McCool]

Highly Recommend Bosch M42 Cobalt bits. Fantastic Quality bits!

[@stevedunford7632]

There are special chemical treatments for bonding or painting galvanised steel. Blasting with copper slag is another treatment.

[@scoutjonas]

Is there no need for triangular metal supports around the outside of the metal cylinder? Can the cylinder take the sideway forces without warping or splitting the weld?

[@ArcticSeaCamel]

The stub mast will be outside of that cylinder. So I really hope that it’s enough! 😅

[@ianlangley987]

Great progress. Enjoy a safe and Merry Christmas. Cheers Ian New Zealand

[@matswilliams1058]

Great to have some extra hands on deck! The masts are realy exiting to get some information about. Cheers and Happy Christmas 🎄

[@bobstephenson3190]

I can’t wait to see the masts. I guess you will install them at a dry dock to avoid overhead utility lines and bridges. Have a great Christmas and new year.

[@ArcticSeaCamel]

Yeah! They’re long way ahead still. And pretty much last thing to install. 😄

[@MichaelP-g5n]

Nice progress, love to see it! On a side note, I can't help myself say something, but I see two thumbs down, which I find so strange. I guess even non-political regular channels like this attract small minded jealous fragile souls.

[@samijokinen6923]

Nice work!

[@nitejazz]

Same question as @diettergraser. Looks to me like you have covered the weep holes with untreated wood in the frames. Otherwise interesting video, I also appreciated the boatshow video, I can imagine it was a mindboggling experience with so much to see and contemplate.

[@ArcticSeaCamel]

Hi! So the holes i drilled were only for the galvanizing process. Not for the actual usage of the steps. The wood will be covered with epoxy underneath so no issue there. 🙂

[@toddablett4493]

Another good video. Liked the overhead shot that moved back and forth, really showed the scale of the boat. The mast supports look so solid. Did you every discuss why you decided to go with the 2 masts and free standing (I think understand the why of free standing) I haven't seen many two masted designs in modern boats.

[@ArcticSeaCamel]

Thanks! I'm planning to have some sort of spidercam eventually to get even better shots like that with the 360 camera :) I have explained the mast thing in the "exterior design" video way back. And that's something we'll get back into many times to come.

[@CaptRobH]

Hi Panu, The maststeps look realy nice, and a good thing that you have them HDG’d. Looking at the weld, It seems a bit thin. Like a TIG wild. Be aware that the shear forces on that weld will be tremendous, and that the weld will have to transmit all that force to the frames/boat. I know that my observation is based on simply looking at an iPad screen, and I may be misjudging the weld completely. For a boat, your size, a weld-throath of 8 - 10mm seems to be minimum. ( but once again, without any drawings or calculations, that is a rough (educated ) guess. ) For the rest,… I love your channel. Greetings from the Netherlands.

[@ArcticSeaCamel]

There's three beads of weld in that seam. Two on the outside and one on the inside. And the cylinder bottom has been tapered to get full contact with the weld. So the weld seam is completely and fully attached to both sides. And it was very well done! You're right, the load will be large. The design has been gone through with the designer so I'm sure it's OK. 😊

[@michaelweitzner9874]

Just a suggestion. You may want to add drain holes to the athwart ship sides of the mast steps. The boat will always be heeled over.

[@ArcticSeaCamel]

The holes drilled were just for the galvanizing process. They dip the parts in all kinds of substances and molten zink so there had to be draining holes for that. There shouldn't be any water coming into the mast steps later on. I guess. 😅

[@ClaireK-v3i]

Start with a pilot hole my friend

[@dietergraser3640]

Step by step you are moving on! But one question: where will the holes in the maststep drain to?

[@ArcticSeaCamel]

Hi! Those holes were just for the galvanizing. No need for them afterwards.

[@peterdguru]

won't there be some condensation within the mast that will need to drain somewhere?

[@ArcticSeaCamel]

@peterdguru Not sure yet how they will be built/installed but I think not. There are only stub masts fixed to the boat that are completely waterproof. The actual mast are then placed on top with bearings. So no connection from outside to in.

[@dennix01]

Hi Panu, What are your favourite metal songs?

[@ArcticSeaCamel]

Impossible question! 🤣 Been listening a lot of VOLA lately…

[@dennix01]

@ArcticSeaCamel cool :-) Thnx for sharing.

[@tobiaslindblom2187]

how are you planning on drilling for the bolts? CNC or try to drill through packing and frame all at once?

[@ArcticSeaCamel]

Just afterwards. It's gonna be little tricky but I think I'll manage. 😅

[@kevinjohnson4500]

@@ArcticSeaCamel Would it be any better to use longer bolts that tie all 3 of the surrounding frames and the mast step together?

[@tobiaslindblom2187]

@@ArcticSeaCamel without damaging the zinc? You have to aim really accurately and use some kind of rig. Not easy without speciality gear.

[@ArcticSeaCamel]

@@kevinjohnson4500 I think they would be too tricky. Very long drill bit and bolts. They’re not cheap either! And i’d like them to be sealed inside the epoxy structure.

[@gregoryh4601]

Just a Thought , This Project will take a Few Years Right _ _ _ _ then save a special fund for the Day you need the Mast. I think we your Fans find a Carbon Fiber Mast for your Sailboat and maybe a Mast Company can have a Return Mast for You

[@ArcticSeaCamel]

The masts need to be designed and built specifically for this boat. There’s no off the shelf-masts of this kind. So making them is part of the project!

[@skyak4493]

Is that standard Finnish customer service, or do you have to pay extra to get heckled at the galvanizer?

[@ArcticSeaCamel]

Finnish customer service? What's that? 🤣

[@eamonnfanton2165]

No shrouds? How are you going to prevent the mast from flexing? It going to have to be a super rigid mast to prevent flex, and even with something like a carbon fibre mast surely you would want some shrouds to reduce the load. Replacing a mast is super expensive, replacing a carbon fibre mast would be substantially more costly

[@ArcticSeaCamel]

Hi! 👋 You don’t prevent them from flexing. Flexing is essential part of how they work! They are more comparable to airplane wing and they haven’t have shrouds for hundred years anymore 😉

[@eamonnfanton2165]

​@@ArcticSeaCamel Shrouds and stays do allow a bit of flexing but it is within limits. At least if they are tuned correctly. I don't think anyone would argue that shrouds and stays do not relieve some stress on the mast in adverse conditions. You are doing without them completely, so I was wondering what sort of mast you would be using. I know high end racing yachts with carbon fibre masts often have no stays or shrouds but they are also designed to prevent the mast springing and the stress damage that might cause to the mast. I'm not saying shrouds and stays are a must but I was curious as to your rigging and mast choice and why you made those choices.

[@ArcticSeaCamel]

So the physics of free standing masts are completely different. Mast that use shrouds are compressed down with stays and shrouds. The mast profile itself isn't very strong. The cables around it prevent it from bending and breaking. They kind of act as separate "outer shell" that take majority of the tension loads. Think of steel reinforcement in concrete columns. Free standing mast however is kind of a tree that tapers towards the top. The essential thing is that it doesn't withstand point loads. Mainsails are connected to the mast with the whole length of the luff. That way the load of the sail decreases gradually to the top. But that also means that you cannot use "normal" headsails that are attached with single point to the mast. The biggest load of this kind of mast is at the very bottom. On the top there's very small load. And the mast is allowed and designed to bend in gusts and that way it kind of "reefs itself" automatically by giving up a little. And all that means that masts like this need to be designed individually for the boat they're coming into. And they're done mostly from unidirectional carbon fiber so that the highest strength is at the bottom and the mast gradually tapers to the top. The benefits are that this way you can make the mast rotate freely 360°. And that brings the fact that with oval shape, the mast itself acts like a front end of a wing, which increases the efficiency of the sail dramatically. Especially when reaching. Normal mast forms a big turbulence at the front of the sail in reaching angles and prevents the sail from performing very well. Also when allowing the mast to rotate, you can turn the sails forward when going downwind. That prevents the possibility to accidental jibes and when two sails are on either side, they balance the boat automatically. (or should) And then there's the fact that there isn't any breaking parts in the rig. There's just the masts. No turnbuckles, stays, shrouds, wire connections, pins or anything to inspect or replace. Easily hundreds of parts that just aren't there.
