Abstract:

A series of modifications was made on a relatively unstable boat. These modifications attempted to increase the dynamic stability of the boat without seriously degrading other small boat characteristics such as light weight, shallow draft, and relatively low cost. This report documents the modifications made and the results of evaluations performed on them. In addition, two equations were developed which predict the Stability Index of a boat, given its weight and maximum beam at chine.
