This has been sitting in the roof of the shed for 12 months, shaped and wrapped in plastic, while other things took priority.
Pulled it out today, and it's not good. Apart from the inevitable small dirty marks and scratches, there are some swellings which I presume is water absorbtion. only small, rising less than 1/2 mm, but I don't know if the integrity of the foam precludes durability.
Shaped to 7'2" x 23" by 17"T x 14 3/8"N x 3"thick. (I'm 6'1" x 100kg and sick of midgets telling me to ride a 6'6"board.'
