Long term robotic sailboats will be required to withstand extreme weather conditions. However, typical small sail power autonomous sailing vessels (SP-ASVs) fall far outside the range of typical nautical stability experience. In this paper, I analyze three problems related to the stability of SP-ASVs. In the first I show that in general smaller boats will need proportionally greater stability, calling for deeper keels with heavier bulbs. In the second problem, I show that a vessel will be unstable while completely inverted if the inverted metacenter is below the center of gravity. In the last problem, I analyze the roll behavior of a SP-ASV in beam waves. I present a number of methods for estimating the roll parameters of SP-ASVs, and show that Olin College’s Blackbody Radiation, a typical small sail power autonomous surface vessel, has a great deal of wave stability in roll motions.
