OK, experienced Jelly web crawlers, can you help me find out these two things?

It is apparently the height. The 127-meter long ship known as Y721 will be the tallest sailing ship. The stepping and rigging the masts after the bridge would require; a place with cranes and space to handle them. That might mean a couple of acres beside the waterway which not gonig to happen in a city that old.

Thanks, @Tropical_Willie. Not sure why a couple of barges wouldn’t work. I have seen some amazing things happen with cranes on barges.

But it could also benefit Rotterdam financially, I suppose.

Did you happen upon the specs? I’d still love to know the beam.

This article has the length and a picture but not the beam. Closest I’ve come to specs so far:

https://appleinsider.com/articles/22/02/03/battle-of-the-super-yachts-jeff-bezos-y721-versus-steve-jobs-venus

So far I have read that the boat, plus mast (I assume laying flat), are higher than the bridge can be turned up (40 meters).
It’s not a done deal yet, because the mayor wants to listen to the critique of many of Rotterdam’s citizens (after the most recent renovating of the bridge, it was promised that there would never be messed with it).
The ‘plusses’ are that we are a maritime city, and this would radiate positively off on us, question mark.
It would deliver some work.
And some money.
That were the plusses.

Also, he’s seen as a dick (as are his toys).

@rebbel Is it a real hot issue where you live? (Sorry @canidmajor for going off-topic.)

@janbb The basics of this issue are really a hot topic, but the reality is that even a mast that tall can be stepped elsewhere, which is why I wondered about the beam. At this point, it seems to be a matter of convenience, which will simply be expensive, and expedite the delivery.
<eyeroll>

@ I know that but I was wondering particularly about @rebbel‘s perspective because he lives there.

“The middle section of the bridge can be raised to allow ships to pass underneath, but apparently not high enough for the new yacht’s masts.”

40 meters or about 130 feet

“As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat. ” Morten Storgaard / June 22, 2021

That means the masts could be 165 meters four times the maximum height of the bridge lifted.

I’m surprised that disassembling/reassembling a historical bridge is cheaper than using tugboats to push the thing to a location that could install the masts (like one that builds oil tankers/cruise ships or something.

@gorillapaws They probably wouldn’t even need tugs, just a pilot. You can bet that that sucker is equipped with a very nice auxiliary engine.
Maybe tugs for the barges with cranes and masts.

@Tropical_Willie Yes, the beam must not be an issue since they’re only talking about demolishing the middle of the bridge for the height.

@canidmajor Good point.

The beam is the width of the boat at the widest part.

^^ I think we all know that.

Try threading a needle eye while driving on railroad ties, with the possibility of dropping the mast or crashing it into the deck. I’ve watched stepping a new mast with the sailboat in a boat lift sling and out of the water.
Just remember these things could be 165 meters long.

@Lightlyseared, @janbb was right, we already know that, the point is I can’t find the full specs anywhere, I’d love to also know the LWL and the draft (variable keel or not?) and stuff like that.

@janbb, I didn’t. I really don’t know anything about boats, aside from how to row one, but I think this is a pretty interesting discussion.

@Jeruba Sorry, I meant the people who were engaged in this thread at that point.

Oh, that’s fine. I’m learning something here, including a lot about who’s boat-savvy. I like being aboard when I have a chance, but I’m largely ignorant of the equipment and the mechanics. Carry on, and never mind me if I can just listen in. I’ll keep quiet now.

The original point of the Q, as expressed by the phrase “experienced Jelly Web crawlers was hoping that someone could point me to a link that expressed why they couldn’t step the masts elsewhere. While I appreciate all the speculation on mast height (which I believe to be a bit off considering that there are three masts, and thus the usual concept of 1.25 would be unwarranted, as that usually refers to a sloop rig, perhaps a ketch or yawl as well, and would be massively overpowered) I would love if someone could find complete specs. I was all over the internet this morning and I wonder if the builders are just being really cagey about releasing the details.

^^ I was all over it too but I don’t think they’re giving the specs out. The articles I turned up were pretty cagey. Maybe a yachting magazine will have more once it’s built. But in the picture I posted all the masts were the same height so it’s not a ketch or a yawl.

@janbb, I had missed the picture! Yeah, they are definitely not as long as the hull, and I still think that they could be stepped with barges and cranes.

But lordy, what a cushy berth to be captain or crew of such a thing! In a younger day I would have loved to be part of that!

^^ Especially since half the time or more Bezos and co aren’t even on board. The boat is berthed somewhere and then the crew is told to bring it to wherever Bezos and his babe want it to be. But I bet they’re treated like crap when the plutocrats are aboard!

I’ve seen yachts of 100 – 200 feet in harbors with bow thrusters to move them around but this is a whole different kettle of fish.

Too much for my taste. Why have a sailboat that you can’t tell is sailing? Ugh.

^^ I agree. I’d spend my millions elsewhere if I had them.

Apparently, the yacht is costing around half a billion…...

On a related note:
More than 1,000 Dutch residents plan to throw rotten eggs at Jeff Bezos’ superyacht if it ends up forcing a historic bridge be dismantled for it to pass throughs

@janbb No, not really a hot issue, only maybe a bit in Rotterdam.

All power to the throwers of rotten eggs! That whole project is beyond classless and gross.

On one hand, I hate conspicuous consumption and privilege.

On the other hand, I love sailboats. At least it’s not a motor yacht.

I’m sure there is a very big engine on that sailboat as well.

Sailboats with a cabin generally have motors. I once (sadly) had to motor a beautiful 35-foot sailboat from Lake Huron through Lake St. Clair to the Detroit River because the air was dead still for two days.

But out of port and on the open water, sailing is akin to flying. The physics of sails and wings overlap. Whether it’s me on a little beach boat or Daddy Warbucks on his yacht, I love watching people harness the wind.

Most of you may have seen this already; good shot of the bridge: https://www.msn.com/en-us/travel/news/a-historic-bridge-must-be-dismantled-to-get-jeff-bezos-540-million-yacht-out-of-dock/ar-AATp39B?ocid=weather-verthp-feeds

It has a short video and mentions the support ship, which will feature a helipad.

“Shadow vessels are a growing phenomenon in the superyacht industry and one more extra toy that their owners want to have at the ready,” says Nicholson. “You see them more and more now as an add-on to a superyacht purchase,” he says. “They’ve almost become a must.”

If Bezos pays for dismantling and restoring the bridge, I don’t see the problem. Unless traffic will be disrupted for a long time.
