Rising and Narrowing: 16th-Century Geometric Algorithms used to Design the Bottom of Ships in Portugal

Abstract

Methods of designing the bottom of ship's hulls were only a small part of the process of building a frame-based ship in Portugal in the 16th and early 17th centuries, but they deserve a careful look. Using a number of geometric algorithms that were already well-known to Italian shipwrights of the 15th century, Portuguese shipwrights obtained the co-ordinates of the turn of the bilge points of the central, pre-designed, frames without the need for making drawings. © 2006 The Author
