Commercial Classification (GZ Curves)

[mopuk2000]

I am a 4th year student of Naval Architecture and Small Craft Engineering at Strathclyde University (Glasgow). My final year project is to research and developed a method of finding and fitting GZ curves for any RIB by taking measurements and coefficients (ideally from the boat, put possibly from the lines plans) and comparing them to known cases. The desired outcome of the study is to find a formula or algorithm to allow this to be done quickly and easily, without the need for a full MCA inclining experiment. This is in response to the requirements for classification of commercially operated ribs.

Does anyone know of anywhere that I can find plans and known GZ curves for any RIB?

Any information on the above or general relevant background material would be greatly appreciated.

Try contacting Adam Younger www.k4plus.com he has designed some excellent ribs , and would be the knowledgeable person to chat to.

You could try approaching some of the manufacturers - especially ones building commercial craft.

Anything that helps and avoids duplicity in coding must be good news.
