As of July 2015, order plans to build a wooden boat skiff at websites such as LadyBugBoats.com and Chesapeake Light Craft. WoodenBoat Magazine provides links to many sites that offer skiff plans.
At LadyBugBoats, you have the choice of receiving plans to construct 14-,18- and 22-foot skiffs through the mail or through an immediate download. Order plans for a 15-foot Peeler skiff from Chesapeake's site, clcboats.com. This boat uses a 8- to 15-horsepower motor and is able to hold up to four adults. Skiff building kits are also available.
At WoodenBoat's Power Outboard Boat's page, skiff designers post information about and links to purchasing information for their boats.
