CAD drawings...

I am looking for CAD drawings for my irwin citation 41 so that I can have a naval architect do a stability test. Does anyone have or know where to get them?

Re: CAD drawings...

On and older boat you would be doing good if you could even find them on paper

Looking for user groups of a boat is one of the best resources of what still exists

If a dirty bottom slows you down what do you think it does to your boat

Re: CAD drawings...

To do a proper stability test, you would need pretty close to full drawings or models which I doubt exist. At some point, there were drawings for the boat but they would not have been made in CAD, they would have been done by a draftsman. The reason that you need pretty accurate drawings is that the center of mass is very important just like the center of buoyancy.

If you just want the exterior hull shape, it is not that hard to take a lines drawing, import it as a jpeg, define points, define surfaces and make a model of the hull. I did this a number of years ago for my boat in Solidworks just for fun. If you can't find the lines drawing, you can take the lines off of the boat.

You can also do a stability test by moving mass around on the boat. This does not account for the changes in the center of buoyancy as the deck edge goes underwater. You could get the center of mass of the boat this way to make your model behave accurately though.

Thanks for the reply.

You are right about the CAD. Line drawings will work but according to Transport Canada a model does not nor does moving mass around.

For a sailboat they need a naval architect to prove the stability with a calculation, or a pull test.

I can haul the boat and spend an extra $3000 or $4000 to have the hull shot with a laser but am trying to do it with simple line drawings if they exist.

Thanks again.
