420 Isaf Sailing dinghy hull

thingiverse

Here is my 3D reconstruction of a 420 ISAF sail dinghy, modeled from a 1959 "plan de forme". In the files, you'll find the half hull and the entire hull, each scaled to 140 mm in length. You can print the half hull using the middle section plane as a base on the heated bed, and the entire hull using a support grid with about 15% infill at 60 degrees. More information about the 420 international class is available here: http://www.420sailing.org.
