A10's suggestion of M14 good, SIC V1 again, 2011 Naishs look good.
This just posted in Buy and Sell.
Know nothing about Naish boards of that age, but it looks like an ocean / downwind shape.
I have what I think is the 17' version of that board, and it is great upwind - fine enough in the nose not to bog in, get blown off, enough rocker to ride over stuff, be safe downwind.
Don't be talked in to a newer, less rocker, narrower, boof nosed, flat water board just because people who have been paddling for 7 or 8 years can get them downwind with impossible footwork.
