Berdasarkan rujukan berikut,

stow = memuat atau menyimpan barang dg hati2 dan rapi di tempat tertentu.

Definisi makna stow ini sejalan dg makna 'menyusun':

menyusun = menempatkan secara beraturan: mereka sedang ~ kursi untuk rapat

Karena itu, dalam konteks di atas, saya mengusulkan:

stow = susunan muatan atau barang

Rujukan:
stow = [with object and adverbial] Pack or store (an object) carefully and neatly in a particular place.
‘Barney began stowing her luggage into the boot’

menyusun = menempatkan secara beraturan: mereka sedang ~ kursi untuk rapat

⚓ U/ barang yang dikirimkan dengan kontainer, pengapal (shipper) harus mempertimbangkan stowage. Wikipedia (https://en.wikipedia.org/wiki/Stowage ) mengatakan:

In container shipping, stowage planning refers to the arrangement of containers on board a container vessel. The stowage of a container ship involves different objectives, such as to optimize the available space and prevent damage to the goods, and more importantly, to minimize the time the vessel spends at the port terminal. Containers will be arranged depending on their destinations (those going to the first port calls in the schedule will be placed on top), cargo weight (lighter containers are stored on top of heavier ones), cargo nature (dangerous goods containers normally are placed at the end of ship, and on upper deck to minimize the loss, in case of fire or leakage), etc

⛵ Karena itu, stowage memgatur tata letak kontainer di kapal (apakah di bawah, tengah, dsb.), singkatnya urutan penempatan.

🙋 Hemat saya, seluruh frasa yang ditanyakan merujuk kepada kontainer (isinya apa, bobotnya berapa, ada berapa, di mana harus ditempatkan), bukan kepada isi di dalam kontainer.
