ROBERTS 420 - Radius Chine Steel or Aluminum Over the past ten years we have been refining our radius chine hull techniques which are now widely accepted as the optimum method of building a round bilge metal boat. As we have received more feed-back from owners of boats already in service, we have been able to refine these hulls and building techniques to provide you with designs that offer high performance, combined with all of the features you consider desirable in a cruising sailboat.As this design was developed it became apparent that this boat was taking on the appearance and characteristics of a smaller version of the hugely popular Roberts 53 G; this fact alone should ensure this boat a great future. Most sailboats in the forty foot range are suitable for either single or twin masted rigs so it is up to the individual owner to make a final choice; with this design we will offer sail boat plans for a cutter, or ketch as well as the cat schooner rig as shown. For those of you who like to create your own design and have it drawn as a custom plan, I have included a profile of the Roberts 420 lines featuring an alternate stern. I would welcome your thoughts on this concept. This design is a well proven world cruiser as many are currently sailing in different parts of the world and the reports are excellent. It can be rigged as a Cat Ketch, Ketch or Cutter. Alternate layouts are possible. You can build the Roberts 420 in radius chine steel or aluminum. The complete boat plans package include many sheets of large-scale drawings, plus full-size patterns for the hull etc. Cat Schooner rig shown - Cutter and Ketch rigs also available |
