That little bit of glass that I can see does look terrible, and I always get sticker shock when looking at new boards anymore. But Cannibal has been around a long time and makes some great boards. I rode one for years. How can you characters say anything about the shape from that pic?
the glass job looks god awful. you can see the cloth where the sanding went wrong. who knows, maybe it's some kind of fancy proprietary construction, or maybe the glasser indulged in too many bong rips before work that day. either way, i'd laugh at the price and move on.
If it's an established local brand, I'm guessing they're just trying the raw/distressed relic look. Don't know why companies do this dirty "relic" look because it doesn't seem very popular on surfboards (kinda like the McRib: it's disgusting, but keeps popping up every year or so). Maybe the shop has some sort of contract with Cannibal that they have to charge full price...if it doesn't sell, it'll probably end up on the internet at discount. I wouldn't buy a board that looked like that.
Cannibal has been around since the early 90's, if not earlier. Well established label and shaped in Florida. While this board may not be appealing to you (or me), it was meant to look like this. I've seen a few shapers use this unfinished look before. Usually hit-or-miss in the eyes of the buyer and I'm sure this board will be gone the next time you go back.
Longboard House runs a pretty tight ship. They probably sold through their inventory over the holiday season and/or you caught them in between shipments. Did you ask them about the board? Or why it's priced at $699?
