Outer Banks 20
The Outer Banks 20 was designed to be an economical cruiser for a couple. The design brief was for a boat with two bunks forward, a potti under V berth filler, an ice box under the companionway steps and enough galley to make coffee and simple meals. All of this had to be able to cruise comfortably on a plane at around 15 mph with a 25 hp motor and use no more than 1.5 gals of fuel an hour. She easily met her design requirements with a wide open throttle speed of 20.6 mph using a Tohatsu 25.
About the Outer Banks 20
The hull is plywood, built over a jig. Most of the “jig” becomes permanent structure. This is not a stitch and glue “introduction to building” type of boat. However, our CNC cut kit option makes if possible for a competent amateur to easily work their way through without having to spend hours patterning all of the components. This model would also be an excellent choice for the small commercial yard.
The bottom is planked with a single layer of 3/8″ (9mm). The sides are planked with two layers of 3/16″ (4mm) ply. The side planking uses the Ashcroft method which means both layers run diagonally in the same direction, the seams in the two layers are staggered.
The entire boat is epoxy glassed outside with one layer of 10 oz. glass cloth to toughen and seal the outside of the boat. The boat is painted with epoxy primer and the top coat is two part polyurethane paint.
Built as designed, the owner will have no more maintenance than a production built polyester boat unless you want to enjoy the beauty of wood, in this case it is desirable to store the boat under cover when not in use.

What else will I need?
Our kit options do not include solid wood for stringers and cleats that you will need. We prefer our builders to locally source this material and rip into long lengths. It is not practical for us to ship these long pieces. If you are picking up your kit from our shop we would be happy to let you select pine boards from our stock to use for your stringers.
The Jig frame is to be made of standard dimensional lumber which can be purchased at any local hardware store.
