i have an extra set of booms with a sail for a mini sunfish. and someone asked me whether the booms are the same size as the larger sunfish? well, i know that the sail is smaller, but i don't know about the booms. does anyone know? i also found out that if one needs a mast for a mini sunfish or a regular size sunfish, you can get one at home depot, lowes, ace, and alot of other electric or hardware stores. all the mast is , is an emi, or electrical conduit. they come in 1o foot sizes and in two different metals. the cheaper one works just fine, and costs about $14.
