535Re: Most Efficient Hull??
- Jan 19, 2005Hi Ron, think you will not find "Maderform Hulls" using Google. Dr.
Mader is a shipwright and has a wharf called "Hycom" in Duisburg
(Germany). Suppose there are many Hycoms in the Google world. When
you send me your adress, I can post you some papers and pics, not
professionally, just from one interested "hydrodymaniac" to another.

of stuff about a Paul Mader who is heavily involved in agriculture in
3rd world areas).
