Not sure profurl made a b series? they have a R series for racing and a C series for cruising as well as a NC I do remember they once also had a P series ??
as for the cost well the normal NC or C series fits over the forestay you need the long brackets for the turnbuckle, I remember these are 200 to 250??? it has been awhile.
as for the sail: sailrite makes a kit for this + the rope = another 200 +/-
But I and the web seam to think there is NO! b291 less you are a Beneteau dealer in FL?? ??
Never jump at a deal, think it through, check it out, and research it; it could be a seal, and stealing is a bad thing!! either way you look at it.
