Cecilia and Jim at ProValor Charters are great to work with. Service with a smile! Their boats are very well maintained and looked after. Not sure that they have a two cabin cataramaran (or anybody else for that matter) but prices are very competitive. In Fat Hogs Bay there is a Riteway next door (not as big as in Road Town, but still is very good) another supermarket and also a truly excellent launderette. Red Rock Restaurant is right there too. Well worth checking out.
