Open Source 13-15m Catamaran Plans

[Pavo1991]

I have few question about catamarans im looking for slow crusing cat whit platform on top nothing for sleeping or something like that just open space...
Thanks for youre time on answering

Is there any interest in this still? I've been designing a 43' performance cruising cat that can be flat panel cut on a CNC. Like the original post my plan is to build a model first. I should have my 1:20 scale RC model water ready in about a week. I vacuum bagged the flat panels and CNC cut them on CNC machine I built.

My original thinking was to creative commons the plans. I have done lots or research and analysis of similar boats, but I'm not a engineer or naval architect so I still will need some help with the validating my calculations and get the plans engineered for the laminate schedule etc. before I would consider building it full size. I'm not really looking for a business venture, but happy to share my work. Not wanting to insult anyone, but I would also love to talk to a experienced Naval Architect and/or Engineer that wants to contribute to the project for not too much money.

I want to know how much weight can cary if is long 30m and wide 17m. and how wide are stops on this parametars thanks

And is it posible making out of steel? Im sorry for my writening i hope you can read

Check the attached document as well if anyone is interested in this.

In the document you posted I am unclear on the terminology.
On the topic of cost estimation it says;
"
LDR is included in estimation, because building a lighter boat needs more time and the materials
are more expensive. In general the building time and cost are proportional to the mass of the boat
mLCC.
"

Can you please clarify what the abbreviation LDR refers to?

Thanks.

From the context, I assume he is talking about Length to Displacement Ratio or LDR

Also for Pavo1991 the design I'm working would not work in steel and has a fairly limited carrying capacity, as that is a trade off for sailing performance.

I finished my first model and there is a youtube video for it. I'm already starting on the second model with some improvements.

Thanks sailhawaii
That will be fun trying to figure out as I am trying a completely new concept
Will soon start building a precise model 1:10 of the concept I am working on.
Who know's, might float or sink, we'll see.
