nose concave?

[timeframe]

nose concave or not?
i have heard that a nose concave is a bad thing but they never seem to tell you why?
does it make the board unstable or are they hard to turn?
there are plenty of nose riders out there without a concave. so why have one?

It generates lift at the nose, but also adds instability.

The concave is a more of a stalling style, making it smooth and stable ride. The nose channels don't slow the board down when in the trim spot at about 1/3 back from the tip. Many better surfers claim to be able to climb and drop with them. Deciding Concave is based on your riding style. If you like slow soul rides on the nose go Concave, if you like fast trim on the wave go nose channels.

Nose channel/channels gets my vote.

Concave sort of acts like a canard on an airplane, less stability and more responsiveness. I'd say 80% of surfers couldn't tell the difference because they wouldn't know how to utilize it properly. It's a matter of adjusting your riding style to the board you happen to be using.

thanks for the advice.
are the channels the same as a double concave?
also, i have a performance longboard, dimensions are 9'3" 22' 1/2" .
would i be able to noseride this board?
will it help if i get a noseriding single fin. i
was thinking of a 9 inch Watermark Squirrel Fin.

I'm not into shaping, but I believe a double concave happens down around the tail of the board. If you look closely, you may notice slight indentations on either side of the skeg, er, fin. It helps to channel water past the fin, giving more control and speed. No reason you shouldn't be able to noseride that board. It's not what you ride, it's the skill you ride with.
