Looking at used Shane surfboard. Detials written on the board are SPT2NJTZ and 7'x 21 1/2" x 2 3/4". Seller has no idea how old the board is or what type of board it is. Looks like a hybrid board, round tail. Would it be suitable for a fit 50 year old 80kg guy looking at getting back into surfing after 20 year lay off on small waves?
