Wow, more pictures, including a side view.
https://www.rcgroups.com/forums/show...t-scratchbuild The airboat had an open chain drive propeller shaft gears and flywheel, definitely not OSHA approved. Here is a photo of the competition, more stable but slower. https://i.pinimg.com/736x/64/57/bb/6...hs-baghdad.jpg

Second linked pic looks more like an adventure ride at Busch Gardens or Kings Dominion.

The Nov 3, 1917 issue of Scientific American had a drawing of the hydroplane on its cover.
https://www.scientificamerican.com/m...sa/1917/11-03/ https://books.google.com/books?id=vM...oplane&f=false (The supplement # 2183, Nov 3, 1917, issue had an article about the peculiar "Electric Properties of Silicon and Germanium" on page 276. It was just an observation about an interesting laboratory phenomena, probably of no practical value.)

The craft in the first three links were operated by a Royal Navy Flight Section in Iraq - around 1916-19.
They were based at Basra, but were used extensively on the Tigris for patrols and to keep the river open. During the Mesopotamian Campaign (against the Turkish and Germans) the British deployed 800,00 plus troops, with the 1,000 mile plus Tigris being the logistical lifeline to supply the armed forces. To secure this lifeline special vessels were used - including custom designed gunboats, and these "Hydroplanes". At the time, the use of Hydroplanes of this type for sport in the UK was not uncommon, so the technology was well understood. --------------------- John, your guesses regarding the last photo are extremely good. As a historian I specialised once in this period and region, and your suggestions are very sound. The gentleman on the left is a German Officer from the period, and indeed looks very much like Paul von Lettow-Vorbeck who commanded the German forces in East Africa. During the campaign, the German cruiser SMS Königsberg was scuttled in 1915 in the Rufiji River Delta. The vessel was then broken up and it's guns, parts and machinery were used to construct other weapons of war. This boat could well be one of these weapons! Back home, I have an extensive collection of books, photographs and papers from the period, and would be well placed to further research this for you, but am away at the moment for a few months. On my return I will see what I can further find. ------------------------------ Splendid finds by the way John!

Fascinating detail Kevin. Thank you, and John, for enlightening us (at least me) on a hitherto unknown weapon of war.
