The wind inclining arm also varies when the boat is heeling. MCA considers that wind inclining moment varies as a cos 1.3(heel angle) function.
If we are speaking of regulatory stability calculation, there is no dynamic effect of water in damage tanks/compartments to take into account....
If you want to learn, there is the MAAT Hydro demo version which is free. When you will be a professional, maybe you will want to use quality...
To be clear, we can say that it is not a problem of physics, but it is vorbidden to take into account trapped air in regulatory damage stability.
GONZO, Please stop : you do not help anybody with such a post. It's a nonsense to speek about calculations you never made !
you are right Gonzo !!
Yes, you are completely free to define the heeling range when you calculate a transversal stability :-180° to 180 °, 0° to 360°, -30° to 80°, 0°...
During intermediary flooding stage, water in the damaged compartment is below sea level. This can be done only with added weight method. With...
Only 2 or 3 "top of the art" hydrostatic/ stability calculation software, as MAAT HYDRO, calculate hydrostatic properties by direct integration of...
For your information, added weights method is used when you calculate intermediate flooding stages, before final equilibrium stage of flooding in...
GONZO : no. Centroid of the curve of areas as explained. Longitudinal origin is the same as the sections origin. Googlise : hull curve of areas
xichyu : Softwares using sections calculate as follow : - The area below the current waterline of each cross section is calculated by...
TANSL : I am sorry, but we can't say that the probabilistic stability is a "third" method to calculate damage stability : It is a regulation, for...
Hoegh Osaka listing : The draft of the investigation’s final report has been sent to stakeholders for a 30 day period of consultation and will...
"Investigators are at a loss to explain how the Modern Express ran into such difficulties. The crew from the Cido controlled car carrier were...
You should try MAAT hydro. It is a solid based software. You can import iges files. You can test it, there is a free demo version.
Nobody is doing something wrong. PhilSweet is right, the solution is easy. With only 2 iterations the result is already very accurate : You first...
The only condition to have a self-righting boat is that the Gm must be <0 when inverted. When CG is below the CB when inverted it is not possible...
Import your pontoon into MAAT Hydro demo version (free) in the iges format, enter the mass and CG of the pontoon, of the plane and you will make...
You can see on the video that the aft watertight door was open at launch. Considering the slope of the slipway, and the yacht trim, you can be...
