Hi all
Photo No. 4 and No 5 are not from the Oheka II.
Photo No. 4
THe only place on Oheka II where there is a cloth root is the rear bench behind the cabin. it is not deep enough fit this photo, therefore the photo is of a different boat.
Photo No. 5
Oheka II was powered by 3 Maybach VL2 engines. These were V-12 engines also used in Zeppelins.
There is a photo of this at the below link.

The photo shows a single row upright engine so this is a different boat also.
