As you can see from the specifications above, the Composite Cruiser (CC) is nearly 8 feet long and nests to a 4' x 2-3/4' x 15" package for transport. As a result, it will fit in all trucks, SUV's, RV's and some cars too. But, the most significant aspect of the design is it weight, less than 30 pounds empty ! It's pretty easy to build, and requires only handyman tools. The "CC" name comes from the mix of construction materials used to build this little gem; Coroplast for the hull and thin Plywood for the bulkheads, floor and decking. and it is all bonded together using Waterproof Construction Adhesive and stainless steel staples.

Look at the photos below, and decide if a "CC" is in your plans.

This is just a sample of the photos in the plans, in fact, much of the assembly is described using these kind of pictures. It is very important to note that the "CC" is not for use in turbulent waters, although it is unsinkable. Also, a 30 inch center module can be constructed to accommodate a second occupant, making the "CC" a great little family boat. As with all small boats, care should be taken in it's build, use and maintenance, to insure personal safety. Always wear a Personal Flotation Device.
