I can't tell you how inspiring it is to watch you progress Panu. this project is a kind of insanely ambitious pipedream... and it really looks like you're going to get it done! thank you for sharing
I have been following your channel since the beginning with great interest. I congratulate you for taking on such a large project. As an avid CNC wood worker myself, I can see how your style of cutting out the parts is interesting and somewhat parallels what RAN sailing is doing, although not the same methods. Keep up the good work!
I found this to be very interesting and thought provoking video on Keels. Your explanation of the advantages described was well done with the white board. Are you suggesting when you using the double keel arrangement, the size (weight & proportion) of the double keels would each be half the size of a single keel arrangement? Do you believe the double keel arrangement to be as efficient (drag coefficient) in low wind conditions as the single keel?
I will be interested to see how you plan to profile those keel blocks back. I hope you have something up your sleeve Panu but I do know you aren't afraid of hard work, however you do it.
@ArcticSeaCamel The best of a short list of options is a portable bandsaw, I don't think the throat depth is enough. Otherwise it looks like a reciprocal saw then power plane and then belt sander. That's all I've come up with.
It looks really good Panu. The progress is real. And as always thank you for showing your thought process and I liked you two keel explanation. Can't wait for the next one, but yes I know we have to wait.
Hi Panu! Like you, I am no expert in fluid theory. But I remember from my military service on minesweepers, when the boats went close together during preparations to connect cables between them, it was important to be careful so that the boats did not get sucked together. I mean, the effect was the same as you described on the blackboard, that is, that the lifting force from the keels mostly acts between them and does not provide the desired lifting force to the boat. I recommend you, if you have not already done so, contact experts at a technical university. Chalmers in Gothenburg for example.
Well, there's no "marine" grade with that name here. Basically all the plywood you'll find here are made with waterproof glues. With this pine plywood (that's not made in Finland) you have to be little bit more careful though. I know that similar is also available with non-water resistant glue.
Really no pros there I'm afraid. All the wetted surface will slow the boat down. Sailboat really needs keel only for going upwind and beam. When pushing along to downwind there's no need for them. Long keel would be better then to make the boat keep its direction better.
I like xx this Channel but I’d like to know more about the day job . Could you show us the architectural aspect of your life? Thank you ( a non sailor who will remain a non sailor)
Thanks! Yeah, there's really nothing special I'm doing. Just basic things with offices, schools, residential houses and such. As being small company, projects aren't very big either. But I do everything that comes ahead really 😅

Well done Panu.
You are an inspiration to watch.
And very enjoyable too.
Keep up the good work.

Hello, you are a modern cnc Viking, i love the project
Very good explanation of the pros and cons of asymmetric keels, Panu.
An understandable analogy is the shape of an airplane wing with lift.
👍👍 enjoying the project
The explanation on the keels was very interesting.
another twin keel advantage is that with two rudders, it protects your rudders better from submerged objects.
Yeah. But for simplicity my boat will have single rudder though...
Thanks for your new vid. The formT works very well!
Another fascinating video! Excellent. Thank you 🇨🇦
Nice one. Looking forward to your next video.🙂👍
So much talent in this project! Were also working on a refit of our 65 power catamaran and its inspiring to see others in the same boat.
Brilliant progress Panu - I love these videos and I might take to watching again from the beginning :)
Thanks! And please do :)

We'll see. I don't know yet!

looks nice keep om rolling thx for videos

Hi! The keel design is of course done by mr. Tanton. :)
OK
Are you using Marine plywood and are you using water tips wood
Well, there's no "marine" grade with that name here. Basically all the plywood you'll find here are made with waterproof glues. With this pine plywood (that's not made in Finland) you have to be little bit more careful though. I know that similar is also available with non-water resistant glue.
@@ArcticSeaCamel I just wanted to know. You are doing a great job. As soon as I see your videos come up I want to watch.
Pros and cons of twin keels downwind in light air?
Really no pros there I'm afraid. All the wetted surface will slow the boat down. Sailboat really needs keel only for going upwind and beam. When pushing along to downwind there's no need for them. Long keel would be better then to make the boat keep its direction better.
Отличный прогресс! Это будет джонка? Паруса. Удачи
fantastico !!
Would a small wood stove using your off cuts add some heat to the building?
👍👍👍👍👍👍👍
