is the only real choice for the discerning boater looking for a south seas feel:
Off equal importance - 16 fiberglass ribs mean it can flex and bend in the wind. 8' is a nice size, much smaller and you may want more than one.
Bimini's are very nice, a bit more expensive, and they require a bit more thought/planning when rigging. However for hot trips, dealing with wind, etc., they are a great solution.
