lofting is a drafting technique whereby curved lines are generated, to be used in plans for streamlined objects such as aircraft and boats. the lines may be dn on wood and the wood then cut for advanced woodworking. the technique can be as simple as bending a flexible object, such as a long strip of thin wood or thin plastic, so that it passes over three non-linear points, and scribing the resultant curved line; or as elaborate as plotting the line using computers or mathematical tables. loft

the two basic categories of vinyl floor tiles are solid vinyl and vinyl composition, clarification needed and the three basic categories of vinyl sheet flooring are homogeneous, inlaid, and layered composite. these types of vinyl flooring differ in manufacturing process and content, ranging in vinyl polyvinyl chloride content from 11% to 55%.
as such it is used in sheet form for boatbuilding and light shipbuilding. as castings it is used for marine fittings. the reliable strength of some grades is sufficient for aerospace use and so they are used for wetted components of seaplane aircraft, such as floats and propellers, where marine corrosion resistance is also needed.
sheet plywood boat building uses sheets of plywood panels usually fixed to longitudinal long wood such the chines, inwhales sheer clamps or intermediate stringers which are all bent around a series of frames. by attaching the ply sheets to the longwood rather than directly to the frames this avoids hard spots or an unfair hull. plywood may be .
the national 12 is a development class where within a set of rules and with occasional considered changes to those rules the boats have been able to evolve over time, moving from wood and clinker construction to high-performance glass and carbon fibre-foam composite boats. one of the most noticeable changes in the boats is the steady increase .
