A wide variety of 3D modeling tools are available today, but the use of these programs is often obscure, and until recently too expensive for the occasional user. Wooden boats are inherently 3D and even relatively minor structural updates require careful measurements, creation of cutting templates, and several iterations in the construction process to successfully integrate within an existing classic vessel. Today, all new boat designs begin as 3D CAD models. This presentation summarizes how common projects (e.g., repowering, interior modifications, and cockpit redesign) for classic vessels can also benefit from 3D modeling. Autodesk's Fusion 360 modeling environment is free for hobbyist use, and is used to capture lines and offsets from drafted plans. Steps to build 3D, full scale hull, transom, and keel models will be demonstrated using the author's Cheoy Lee Lion sloop (designed by Arthur Robb in 1949) as an example, based on plans obtained from Mystic Seaport Museum.


Jim Waite

Jim has loved wooden boats since before building a 15’ Acorn sailing skiff 30 years ago, Currently he lives on Orcas Island and is the caretaker/owner of a 35’ Cheoy Lee Lion sloop with a teak-planked hull built in 1962. With his engineering background, Jim has often looked at... Read More →
