Jiff they look the same to me and we also received them out of the back of 60cwt. Those bastards are heavy, it was pitch dark and then you have to put them together then carry them down to the river bank and launch them.
I had a further river crossing in Korea where they used rubber boats and the RCE handled the operation. What a difference, they had me into a lifejacket and in the boat in nothing flat. Being done in daylight probably helped too.
