8th grade project

I am drawing and building a boat. I am going to draw 15 foot boat. I am going to build a boat out of aluminum. If i cant build that aluminum boat i am going to rebuild my dads friends small sail boat. But i am hoping to build the aluminum boat because i want to learn how to use metal tools like welder and the grinder. I already know how to do wood stuff and fiber glass. I really like wood but wood you have to sand and stain or paint. Fiberglass you need time patience and sanding. Metal you need to cut weld. From my dad He said he likes aluminum instead of wood because it is less mess and it is easy to clean up. Wood you make lots of mess and lot more work and it is hard to clean up when its wet. One thing i heard from my dad is it is colder to work on aluminum because it suck your heat out unlike wood. But wood you need to work outside rain or sun. I like fiberglass because it is fun, it's messy and it is hard. aluminum you can buff it until it shined like a mirror. I want to learn aluminum stuff but not steal. i do not want to learn steal is because it rust and i hate the rusty feeling and it takes more work and it wont last as much as aluminum because aluminum don't rust.
