Thanks Dolfiman! I have yet to read the instructions and previous post and understand what method this uses, but can this be expanded to speeds of...
NewSalt, I already apologized to you and suggested we move on. Repeating old accusations, suspicions and talking points is "rubbing new salt into...
Again you might get some data by using prelimina.com. From what little I understand Prof. Basic implemented a prediction for how an immersed...
Oh now I get it. Yeah fun idea but also not sure if such an amount of shape morphing is possible. Stretchy fabric wouldn't make a good wing then....
That you could make your own inflatable wing is pretty cool and could be useful to build an ultralight wing. But you'd still need a viable design...
The hard chines would be rounded with a 5 or 10cm radius and stay below the waterline so shouldn't give turbulence. I added a graph for the...
Not sure how relevant for or how accurate this is, but I done the same for my idea of a simple to build "harry proa" style hull catamaran. It's...
The vertical lines represent the froude numbers. The speed range I ran prelimina ran from 0 to 10 m/s (= 19.4 knots or Fn 2.38) in 21 steps....
Ok so looking at the 1.8m long "Wigley" hull catamaran series in prelimina (which matches experimental data until Fn=1) you clearly see this hump....
So presumably what Woods calls semi-displacement is what ad hoc describes as "ventilated transom" with flat flow aft? ("My Skootas use semi...
Saqa, another thing you could look up is "Bixel WIG". There are a ton of videos and experiments in the RC range you can find. But I didn't find a...
To be honest I question that too, and wouldn't look forward to explaining this to the water police. But this is as far as my curiosity got me and...
Sorry, all I've found is that this is the opinion of both organizations. Ok there is also this for Germany ("Craft that cannot exceed 30m above...
You could test this out by exporting some basic hull shapes in obj and testing them in prelimina.com. It takes a bit of time to figure out but the...
Maybe rough exterior, blemishes, defects, mistakes and flaws need to be forgiven for both boat exterior and their builders ;)
