Most probably damselflies -- we get lots of them around the pond here...

Did you look that up on Google? 😉

Agreed -- I was having a little pop at the people who ticked me off for daring to suggest that there might be useful information out there on t'interweb... 😉

You could always look it up on Google... 😉

That often happens with dirt-cheap Scancom deals on Amazon, move fast or you miss them...

Yes 🙂 It is a great deal if you're happy using Three. If you prefer EE then there are still great deals from Scancom, but considerably more expensive than on Three... 😞 Several here: https://www.3grouterstore.co.uk/product-category/4g-antennas/ https://www.3grouterstore.co.uk/product/fullband-colinear-mimo/ Or you could get one of the roof-mounting puck/fin-type antennas which are less obtrusive then the Poynting panels -- and probably work better when mounted close to a metal narrowboat roof too... 😉

That boat does indeed have much finer lines than the Duchess Countess, and would obviously go faster... 🙂 Thanks for providing actual timings for the Lancaster canal flyboats (is that what the photo is of?) which backs up the 8mph (or maybe up to 10mph allowing for stops) claim -- so my speculation based on the Duchess Countess was indeed wrong 🙂 (and I'm perfectly happy to admit this, as always when actual facts are used to show this rather than opinion and shouting...) Still nothing to show that they actually used solitons to achieve this speed though -- I would have thought this would have been reported (like in Scotland) if it was actually the case. Unless evidence shows otherwise... 😉

Plenty of information out there to be easily found in a couple of minutes... 😉 https://the-gist.org/2012/07/how-a-scottish-naval-engineer-and-his-horse-discovered-solitons/ http://www.ma.hw.ac.uk/~chris/scott_russell.html https://chalkdustmagazine.com/features/its-a-particle-its-a-wave-no-its-a-soliton/ "...eight or nine miles an hour...for a mile or two..."

Yes it's a flyboat (the Duchess Countess). Did it go faster than normal? -- yes, obviously, it "reputably" reached 6mph. Did it use the soliton effect? -- probably not... 😉 If you ask the Vicprop calculator (for displacement hulls in deep water) how fast a flyboat like that pulled by 2 horses might go -- and assume 60' long x 6' wide x 1.5' draft (displacing only about 8 tons), and allow 3hp engine power into a prop (since 2 horses don't have any prop slip/loss) it comes up with 5.2mph, which is still not the 6mph alleged above. To get the 7-8mph referred to in the newspaper article you'd have to use the soliton effect. Chances of the mythical 10mph -- nil... 😉
