Hydrostatics

[Roger C.]

Hi,

I been working in Solidworks for some time designing sailboats and kayaks. I did allready build two of my designs in plywood that i'm very proud of them.

I didn't do any hydrostatics or stability calculation of them, all the design has been made by eye and actually the final result in practice is very very good. But i would like to know how to have control over the final model in the water and play with the calculation results to optimise the model.

If somebody knows a good internet address where somebody like me, with no naval ingeneering education, can be able to learn how to calculate the hydrostatics and stability please give a hand.

A Solidworks addin to automate the task would be nice to have
too.

thanks.

Hi Roger,

There are quite a few sailboat and kayak sites on the net, and many of them talk about stability etc. Some are quite detailed and usefull.

Try google search engine , and put in your search terms. You are sure to find what you are looking for.

Good luck. dionysis

Roger,

This internet that we have all grown addicted to is not the best place to start to learn what you want. There is both too much and too little information to digest and no way for the novice to discriminate between the right and wrong of it.

Go to your library or bookstore (ABE Books on the internet is a great source) and get Skenes "Elements of Yacht Design", John Teal's book or several others that will start with the basics and carry through with a complete introduction to the subject. After you learn the basics, then you can use software to draw the pictures and make calculations.

Too many people are starting with design software with no background in what makes a boat tick.

I will have to plead guilty Tom. I started out with the attitude that, “hey this aint rocket science.” Now after 5 years and about 40 books, including the ones you mentioned, I find I’m looking for more answers than I knew there was questions.

Roger, I think Rhino will accept SolidWorks files. With the marine plugins you should be able to get your stats.

There is very little available on the Net for hydrostatics and stability. This site is the best that I have found but the scope is limited.

http://www.nadn.navy.mil/NAOE/courses/en200.htm

But at least it gives you an introduction without having spend anything.

Bonne chance.

Here are a couple more links on hydrostatics Roger:

This one is from the navy:

and another link that explains stability:http://persweb.direct.ca/tbolt/stabilit.htm


Here is are a couple for kayaks especially:

Sometimes it's a good idea to browse and get yourself immersed, even if you do not know much. Maybe this way you can learn enough to ask more specfic questions.

Hope this helps, dionysis
