Product Description
21' Rona Yawl Plans
This little ship has been designed for the sailing author Derek Harvey and incorporates many ideas gleaned from his years of sailing experience. The starting point for the design was the requirement for a trailable boat with comfortable internal living space for 2 with a large and practicable cockpit area. The rig had to be both efficient and easy to use from the cockpit and she had to carry a large outboard for motoring out to sailing grounds. Clinker ply construction using 7 planks per side was chosen to give the hull a sweet appearance which was fairly easy to construct (details and plank shapes are also given for stitch and epoxy construction and she could be strip planked). For easy trailing she has twin pivoted bilge boards which do not encroach on the accommodation and are housed under the bunks and she carries some water ballast. Inside there are 2 large bunks with galley and saloon/chart table and a locker for a Porta Potti. The layout could be re arranged to take more berths. She has a foredeck well and she carries a gunter yawl rig for good balance under reduced sail.
