ABYC is a voluntary standard, not a regulatory standard in the US. US regulatory standards for level flotation and similar only apply to...
Thank you.
Questions you should ask yourself: Why will customers want to buy you boat? How will customers perceive it as being different from other available...
In addition to gonzo's comments: More expensive Heavier - depends on what is the same between the boats being compared (overall beam or usable...
Thank you. Anyone interested in the no-slip boundary condition should take time to carefully read this.
I did not say or suggest the "stationary part of the boundary layer" is "much thicker than the mean free path of air (N2, O2, etc)".
Have you considered trim tabs or interceptors, both of which can be adjusted to suit the speed?
The thickness of the portion of the boundary layer with zero speed relative is smaller than can be resolved using the scales of fluid mechanics....
Velocity is a vector quantity with three components (in a 3D world). It has both a magnitude and a direction. Speed is the term commonly used for...
Full size boats use a "rub rail" over the joint. Some full size boats apply gelcoat along the joint after grinding the joint smooth, and then...
Did you try downloading? They use a "shopping cart" system but the cost of each paper is 0.00.
Sailor Al, do you understand that the entire boundary layer has zero velocity relative to the adjacent surface? If so then your understanding of...
Potential flow modeling has been at the core of theoretical aerodynamics for the past 100 years or so, in particular circulation, point vortices,...
Many, many experiments have shown the general validity of the no-slip condition. If an individual wishes to believe it is not valid that is their...
The first assumption in fluid mechanics is the fluid can be considered as continuous, without needed to consider the individual molecules of the...
The above quotes of mine from May 2021 are applicable today.
@Sailor Al, perhaps you should review the definition of an analogy. Here is one example: analogy...
There are numerous locations used for measuring deadrise angle. When specifying a deadrise angle the location should be stated, such as "at...
I do not see any reason to continue to engage with Sailor Al. He claims that he wants to learn about aerodynamics and then makes claims like the...
There appears to be some confusion about the non-slip condition and where it applies. The "no-slip" condition only applies at the surface. It does...
