Leo is a British/American boat builder reconstructing a 111 "classic sailing yacht" up in Port Townsend, WA. He typically releases 1 video per week, and they are often wonderfully shot & edited visual meditations on the nature and practice of manual construction. Things have become a little more uptempo musically since the move to the boat yard at PT, but there's still a delightful sense of calm, steady skillfull work throughout.

And even on this much smaller project, yes, steam boxes were important when forming the new hull. [ EDIT: I got this wrong. No steam here. ]

And the Tally Ho restoration is only two years from completion at this time.

... and a sailor! :)

Are you sure? I don't remember them using steam boxes for the Tally Ho. I think they use sawn frame construction instead of steam bending them.

Maybe you are mixing it up with Acorn To Arabell? It's an other youtube channel who do definitely steam bent a lot of frames: https://www.youtube.com/watch?v=zOFP4Rop4u0

Fairly sure they built a steam box in an old shipping container at some point along the way. Not sure which components it was for.

I remember them doing that, was that for steaming or to dry out green lumber?

Maybe you mean the old shipping container they use as a kiln to dry out the planks?

I don't think they use steam there, quite the opposite if I understand it correctly.

Probably you're right and I'm wrong.

I absolutely love this, thanks for the recommendation! It's wonderful to watch but has absolutely cured me of a desire to own a wooden boat, I'll be happy to follow his progress from a fibreglass boat instead!

I looked at the picture, and thought, what? It's in a busy harbor. There's a slight wake, so it's moving and not anchored. It's headed for a wall. All the sails are furled. It's either under power or adrift and in big trouble.

Turns out it's not quite early 18th century. It has an engine. And a lot more. Below decks, it's quite modern.[1]

"The vessel is fitted with two adjustable propellers and two 404 kW engines. The electricity supply comes from two 180 kW generators, in addition to an emergency generator. Apart from propulsion machinery and generators, the engine room is equipped with pumps, a boiler, a bilgewater separator, and an air compressor."

"The front cargo room has two tank rooms filled with technical equipment. Between the rooms, there are five waterproof steel bulkheads. Furthermore, two large floodable bilge pumps are able to pump up to 500 tonnes an hour. The fuel room is located in the aftmost tank room and can hold 36 000 litres in total. The full capacity of the machinery and generator consumes approximately 2000 litres a day. The vessel’s toilet system is connected to 12 toilets around the ship and is also located in the stern. The water room is found in the front tank room and contains water production equipment and a laundry room."

"The galley is located one deck below and is an ultra-modern compact kitchen with a convection oven, tiltable pans and cookware, a cold bench, and more. The scullery is located next to the Galley, containing a dishwasher and other equipment."

It's even air conditioned.

That's a good thing if they want to sail it around the world. As is an adequate maintenance budget. Wooden ships are high-maintenance. See HMS Bounty Replica sinking.[2]

Sadly I missed seeing this ship when it visited Stockholm a couple of months ago, but I’ve seen it when docked in Gothenburg. I’ve never been on board sadly, but even just looking at it from the docks it’s such an impressive sight, I found myself just staring and marveling at it quite a while.

If anyone here on HN is anywhere along the route of the trip to China and you’re in to this sort of thing, I highly recommend going to see it. Even if you don’t much care for tall ships, maybe go see it anyway – you won’t be disappointed!

Also worth a visit if you’re in Stockholm is the Vasa museum[1]. It’s got a lot of good stuff both about recovering the ship as well as the construction and why it failed so spectacularly. Iconically, the story of the Vasa ship has so many parallels to modern day development that one might be tempted to draw the conclusion that we haven’t really learned all that much since then.. :o)

Not many men have the opportunity to go down as the captain of a tall ship these days. I'm not sure if that would enter my dying thoughts, but I know people it would.

After reading about how they built the replica of the Mayflower and then promptly sailed it across the Atlantic despite having only book knowledge of how to handle such a ship everything else seems like cheating.

Steamboxes that large aren't common but steam bending of wood has never been 'lost', it has just been substantially scaled down from how common it was in the past, just like many other techniques for working wood and other materials. But in bespoke furniture making it has been in continuous use for centuries. I'm really not sure what part of it was deemed to have been lost.

Yeah there are people making canoes and small boats in Ontario that use steam bending.

Then there is this classic film by the NFB in Canada about how one man made a cedar bark canoe using old fashioned techniques.

Ah yes, I totally forgot about those and it's not like I haven't seen that kind of thing being done in practice in Canada, a friend of mine built one like that, and it came out very nice.

Steam bending was and is still used for mass-produced furniture: https://en.wikipedia.org/wiki/No._14_chair

And there are also very interesting modern takes on bending wood such as compwood: http://compwood.com/processen/

The wood is heated and compressed longitudinally. Once cold it stays (super) bendable as long as it is still wet.

This isn't related to shipbuilding, but it IS related to steam-bending and the recovery and preservation of lost artisanry:

I hope to live to see a similar article someday on building the Saturn V or even Concorde, both systems built by hand with minimal to no computing and neither buildable today.

(though modern alternatives exist, just as modern alternatives to the Götheborg exist)

I will note that just about any old technology is 'not buildable today'. Nobody today 'can build' a Ming Dynasty iron-smelting furnace, because we don't have detailed instructions for how to do so.

But with a lot of work, we can figure out how to build a pretty close approximation. The more precise the tolerances, or the more parts something has, the harder the 'figuring out' step is.

It seems SailCargo has also been working with steam boxes to construct their new wooden sailing cargo ship, Ceiba. https://www.sailcargo.inc/

You can see workers pulling a plank out of a steam box in their latest video update around 2:45: https://piped.kavin.rocks/watch?v=LW56HDEYzcA
