The containers look to be 2 studs wide which makes this about 1/2 minifig
scale. Do you know if the design scales up? I mean if you had two (or
three) sets could you build it wider and longer and have a minfig scale
ship? I guess it comes down to the superstructure. Maybe you could pass
this question on to the design team.

Well, this comes down to simple math: if you want to double a
threedimensional object in all dimensions, you basically need 2x2x2=8
times the material. Thats the easy answer.
|
That’s true for a solid object, but as the 8wide fans point out to me all the
time when I use this scaleup against them, this object isn’t completely
solid. you may not need 8 times as much hull brick to make a 2x hull, for
example. (howver you’re going to need a lot more interior. (and you allude to
that below))
|
Excluding all internal supports and bracing, what we are really concerned
about is surface area, since that’s the brick we see. If an object is scaled
up 2 times, its surface area goes up by a factor of 4. Thus, you would need,
at minimum, 4 times as many bricks to make the object twice as large. Use
your own to build the internal structure and you’re good to go.
So, to scale this ship up to something approaching minifig scale, you’d only
have to buy 16 sets. The big problem would then be piece distribution, since
we’d have way more of those 1x4x1 wall panels than we need, and not enough
basic bricks.
How about that, my engineering degree is coming in handy :)

Compare with my 40ft container 40’ x 8’ x 9’6” high:
Apart from it needing the Maersk blue bits for the star, I’d ideally like to
make a ship to 8mm:1ft scale with these containers onboard, multiplying all
dimensions by 4! The ship would be 2.8m long and would have to be transported
in sections, probably modules on 48x48 plates! I like the thought though,
especially if I had a warehouse full of railway to go with it!
The bow plate is 12-wide and you’d need to make a 48-wide one for a minifig
scale ship. Also, the containers start with 2x8 bricks but it’s 1-wide bricks
that you’d mneed for building large containers.
The ship is essentially a flat piece (the deck) with a cuboid piece (the bridge
etc...) on top, so the deck area scales up by a factor of 4 for every doubling
of dimensions and the bridge volume by a factor of 8.
Therefore this set doesn’t scale up very well :-( but does any set? Anyone who
really wanted to, and needed 16 ships, would have to get 3 friends to order more
for them!
Good to see more dark red pieces though. I’d like bricks and train windows in
dark red for doing proper British coaches.
All those floor studs (25 per ship) will be useful as train buffers if I use the
parts for other things later.
