[fl12} *the fl12 is a new version of our fl11.* general purpose skiff, very easy to build. oars or outboard. plans updated in 2015.. Outboard runabouts, hydroplanes, and speedboat plans and kits for a variety of construction methods designed for the home boat builder.. This category is somewhat arbitrary, like many in our catalog. many of the inboard designs have outboard options and there are designs in the cruiser and work boat.
