Interesting, a behavior we desire to achieve when building a boat.. I like the simplicity of the tetrahedon, but I find the Gömböc more...
Don't be to harsh with your self built boat. Considering the restrictions - time, built-by-eye, maybe knowledge you didn't have before - you've...
Why not simply use GM = KB + BM - KG with BM = I / V ?
I didn't read the whole report, I stopped at the description of the loading conditions. Are you sure a VCG of 0.5 m is reasonable for the crew?...
Since you're into building on shore your design is not bounded to any requirement a floating object has to float. Your design and it's form is...
Thanks @gonzo, I think this thread can be considered closed because it was not more than a lucky coincidence and scientifically nonsense.
Hi Hamza, as I haven't worked with Catia yet I didn't experienced issues but I've had issues exporting from Rhino to Maxsurf. What exactly do...
Not sure how the future of AI and NA will look but I expect much stuff to happen in that field. I'm also unsure if I'd be glad or sad about that,...
Hey guys, Do you think there is any need for more/ other NA related software? What are you missing in the software you use currently? Would...
IF a change of density happens you'd sink in proportionally to that change of density.
I think I understand what DCockey means. 1) Heel the hull arround longitudinal axis without adjustment for trim. 2) Heel with correction for...
Thanks, maybe that was the excact thing I was looking for. Probably I've ever heard of the instantaneous centre of rotation at school in dynamics...
When speaking in terms of 6DOF: x = 0 (fixed) y = 0 (fixed) z = f(displacement) phi = heel angle (fixed) theta = f(LCB, LCG) psi = 0 (fixed)...
Thanks for these threads, I like reading "old" stuff which still is and will ever be relevant. But unfortunately there is nothing really new to...
Nice, now we are getting somewhere interesting. I'll dive into this the next days, ship motions was a tough course at school.
Thanks, @Heimfried. So the euqilibrium cannot be found in a simple manner, I will continue my method and can only simplify my program by...
The righting moment is a result of transverse missalignment, I think the longitudinal position of CoB and CoG still should match.
So large angle stability is calculated without taking care for trim? I know that I overthink things often, but I doubt that trim is not taken into...
Thank you both for your replies. I know that displacement cannot change. I also know BM = I/V. I'm programming a Rhino plugin for large angle...
Hi, what would be considered as the centre of rotation of a boat or any other floating body? I'm asking mainly for heel situations, when...
