I am very much interested in building a Colin Archer / Willim Atkin Double ender. I would like to build the vessel from Steel, round bilge LOD of 50+ ft. If staisfactory steel plans are not available I would consider wood, but I do not want to utilise carvel wood constrcution as I am informed it is much to difficult. Is any one able to recommend any design plans along these lines. I know of george buehler designs but he only utilises single chine. I am not to familiar with Arvher designs..I should be... but am not for the moment........So i would appreciate any particular ecommendations of designs.
