Coastwise Marine Design Inc. has redeveloped the Ashley Butler design, Mayflower 50, for external lead ballast.  The vessel will be built as per his spec which is carvel planking over a combination of double sawn and steam bent framing. Ballast/displacement ratio will be 30%.  Mr. Butler's sail plan was originally drawn as a yawl, but this version will be cutter rigged and better suited for the balance. CMD will also provide mylar templates for all the sawn framing, CL timbers and transom.
