This is an original and rare circa 1980 prone paddleboard - formerly used by Newport City Lifeguards.
I personally paddled 100’s of miles on this board, and it could last many 100s miles more.
This board is a collector’s item and/or your next training board for racing or big wave surfing.
It could use a fresh coat of paint and a few minor ding repairs.
I think it’s epoxy foam and glass. It is NOT a soft top.
It actually surfs, so you can nab some waves during long paddles along the coast.
Approximate dimensions are 12' x 21.5" x 4.75"
