Atlantis Series kits are for real modelers. The difference compared to the Atlantis Initio Series is relatively small, as the system and building principles are the same. Both categories require hull construction and have the same quality level of materials, instructions, etc. The difference is that the boats in the Atlantis line are (as they are in real life) bigger ships, have more difficult hull lines and feature many more details and accessories. Because of this they are more difficult to make. A second bundle of strips for the hull is included with each kit, though the bundle is not included in the instructions or in the official content list of the Atlantis kits. We offer it as a bonus because the hulls are hard(er) to make and the second bundle of strips can be used if the final result is not as excellent as desired. The wood is laser- or watercut. 1/51 Enterprise Kit #80837, Constructo Wood Model Ships 1/56 America Kit #80827, Constructo Wood Model Ships 1/48 Robert E Lee Riverboat Kit #80840, Constructo Wood Model Ships 1/50 H.M.S.
