My 8 foot blackbird thickness is listed as 3 inches.
Measured it and it is slightly more than 2 inches at rail. It is 3 inches at the very maximum cross section in the middle of the board. This board does not have the float that it should.
Volume of 61 liters must be way off.
Still like the board. I thought it would be more floaty.
Performs well but I am dissatisfied with the dimensions being somewhat misleading.

I bought this board 2 years ago (flouro pink) - the 9'1". I am an intermediate surfer, but had been out of the water for about 20 years. This has been the perfect board to get me back into surfing and help me transition back to a short board. It makes it easy to catch waves, it is a high performance board and turns almost like a short board, but it is also possible to nose ride it. It is fast and turns well. The finish has been good. I use it at least once a week and there are no more than the usual bumps and bruises for a board of this age. I would get it again.

A young guy at Aloha Manly told me that this board would be good for me. I took his word for it and decided to give it ago. Wow I was blown away at just how right he was. The board floats me well, I seem to be paddling faster than I was on my Mal. Once I am up and riding I can go anywhere I like. Having lots of fun and feeling about 15 years younger. The board is well made and the Blue Tint colour I got is awesome.
Great value for money.

Bought the 8 ft blackbird from the first release at the local l,ongboard shop and was surprised at the great glass job on the resin tint and re enforcement patches, Im 95 kgs and a back foot surfer and the glass job is holding up great.Its also a good all round compromise between traditional and modern mid length performance.
Great value and quality for the money
