This is an in-depth guided tour of the Flow 19, a trailable sport cruiser sailboat designed by Atelier Interface and built in France by Prodesign 3D. This lightweight design has a fully retractable swing keel that makes possible to launch the boat from shallow ramps, beach it and explore shallow waters.
