Hey guys,
Im a beginner to boats!
Im confused what material I should use to build the boat!
Also any website which offers free plans to be downloaded!
Thank you 

Why don't you go through the posts in this subject on the forum? There are plenty of links and build logs - from simple to advanced projects. You will even find most material sources

Already done that!
But i'm confused what material to use
there are lot of materials but im not sure what to use
Im thinking of building an outrigger or a catamaran

Have you given any thought to size (dimensions, weight) and power unit?

If you have, you would know where to start!

Balsa sheets ranging from 2.5mm to 6mm would be good ideally for building outrigger and other boats. Traditionally balsa and plywood are also used to built boats. You can use depron to build airboats. I have built a couple of airboats with 3 mm depron. But that being said, it depends on what you intend to build, power, speed , size , you would have to take all into considerations.
