HYDRODYNAMICS OF SURFBOARDS

FINAL YEAR THESIS BY MICHAEL PAINE

BACHELOR OF ENGINEERING (MECHANICAL)

UNIVERSITY OF SYDNEY

1974

Notes:

1. The thesis was prepared with a typewriter. The attached pages werescanned at low resolution to minimise file sizes. My apologises for thepoor quality.

2. The section on stability theory has been omitted.

3. Pictures can be viewed athttp://www4.tpg.com.au/users/mpaine/thesis.html

4. Shortly after graduating I built a stepped hull surfboard. It worked asintended once planing - it had a very strong resistance to nose-diving-but a serious problem was the extra drag that the step created whilepaddling. This made it too difficult to catch waves.
