A few months ago I came across
this junk, taken from a film of Hong Kong harbour in 1958. It has a top panel which is much wider (vertically) than the other panels. I found it interesting, but dismissed it as a one-off. Maybe he ran out of bamboo?
Today I came across
this junk, also from Honk Kong where it was built in 1962, also having the same characteristic top panel shape.
Can anyone shed any light on this? I assume it is a characteristic local to Hong Kong, but maybe not. Why this particular shape for the top panel?
Informative or entertaining guesswork also welcome.
