If you're in the market for a rewarding summer weekend project, then check out the Balmain DIY Sailboat Kit ($2,590) — it has everything you need to build a fully-functioning small sailboat in your backyard or garage workshop. The kit comes with all of the wood, hardware, sealant, and glue you need, along with a sail, ropes, mast, boom, and gaff. A step-by-step instruction manual with detailed construction notes will walk you through each step of the process. All you need to provide are some simple hand tools, aquatic paint, and elbow grease. Also, a nearby body of water wouldn't hurt.
