This is what happened to my 2 month old Naish MANA 10' AST a couple of weeks ago.
my 55kg wife in 4 foot point break, she is not a surfer and was hanging to the out side of the main break to practice her paddling onto waves and her surf stance, had a couple of waves break and she bailed off but nothing too big, she said it was great fun.
after returning to shore with no problems, I walked down the beach to go for a paddle and was shocked with what i saw.(pictures below)
This board has paddled my 100kg 6'2" frame around in the same conditions with no problems.
after returning the board to my local shop, on the same day.
The shop contacted the Naish Distributors and sent Pictures.
Return comments where "NO WARRANTY" it has had wave impact "WHAT"
So if you buy a Naish MANA 10" make sure if you take it out of the lake that it's only very small waves
.Maybe lighter is not always better, i guess i am looking for a new board.

I am glad i paid the extra $ for a top Brand
