Marine    Design

     Welcome to the website of McGowan Marine Design, Inc., featuring the design and experimental work of Laurie McGowan.  Opened in 2001, this is a full-service office providing custom and semi-custom boat design services: concept drawings, CAD (3D modelling and movies, 2D plans, renderings), 3D 'unfolding' to 2D patterns, and stability, speed, powering, propeller, sail and rigging analyses.  I also complete Transport Canada fishing vessel plan submissions and stability booklets, and experiment with fuel and energy saving techniques and devices (with some excellent results!).

                              All vessels and structures on this page were designed using TouchCad: here is a small copy of the movie that I presented while a panelist at the 2012 IBEX show in Louisville, KY. (Windows version here)  And also a fun project that Claes Lundstrom - creator of TouchCad completed in 2013: the Despicablimp!  I am a TouchCad beta tester and get a lot of help from Claes when finding a software problem or need a special boat design-related feature in the program.  I don’t receive anything from him except programmer and software design help.
