BIC Electric Rock Windsurf Board Specs & Suitability

Question
I have a an old 8'8" bic electric rock windsurfer.  I am trying to sell it and don't know the specs on it.  How much weight can it hold and is it a good board for beginners or what type of board is it used for?

Answer
I do not have the specs for this board however at 8'8" it is definitely not a beginner board.  This is a high wind board.  It will probably not hold more than 110 lbs without sinking.  This is what used to be known as a sinker board.  I will guess it is about 85 liters. Big electric rocks are probably about 10 to 15 years old.
