whats everyone's thoughts on having a concave in the nose of a board when it comes to noseriding?

I know now you don't need them to noseride a board but do they help a bit?

i think they do....but my experience is limited.

My 2 cents says yes to nose concave for nose riding.

In my limited experience, nose concave should put air under the front of the board, creating lift, so good for nose riding.
But I'm a bit sensitive on the nose topics.....

I always felt that any widish flat nose could be noseridden, but I preferrer a slight concave.

In fact, I prefer a slight concave in every board I ride.... even pointy little thrusters.
The concave seems to provide control, as well as lift, but I just ride them... I don't have a great knowledge of design.

When noseriding, the flat bottom nose seems to vanish without warning, but the slight concave allows me much more control over the board, from the nose.

Yup, I agree......all the boards I have had with wide noses (Nalu 11 4, Gong NFA, and JL Striker) are all fine for getting up near on the nose but I reckon a wee concave would have helped. The big Allwave I had and the JP Aus widebody 8 ft 8 have the concaves and I think they work/ worked really well. Just feels a bit less slidey on the nose....

Concaves can work in different ways. They work mostly by allowing different rocker lines in the center compared to the rail, and also deflecting the water as it flows along the hull sideways.

As others said, basically a flat hull is fastest, so concaves trades speed for control, which a good thing for noseriding. Thin nose rails are also very important so the nose really penetrates the water and grips the face, more important than concaves in my opinion, and it was the problem with early noseriding SUPs: too much volume in the front rails.

Thing is Colas....I've had boards with loads of volume (the old Allwaves) and those noseride better than boards which are supposed to noseride well e.g. Striker, big Nalu. I also have a friend with a Starby 9 8 Element and he reckons that noserides better than any other board he has had.

Idea is the concave gives lift in the nose whilst the tail should suction to the wave, slowing it down and trapping it in the pocket.

Rocker is probably more important, to much nose rocker and it will bog.


This is a great article on nose riding and board design.

I have a Jimmy Lewis Black & Blue that has a big concave, I really notice the extra lift when paddling for a wave, but the really big difference over my striker is the way the B&B holds the face, whereas the nose on the striker tends to slide down the face if I don't concentrate.

Love to try one of those B&W .....the Striker is a fab board .....if only it had a small concave I think it would work better on the nose but hey, I'm no expert

The old round nose Allwave was the only board (prone included) that I ever managed the elusive "Hang 10"
Twice, and really solid rides, not quick trips.

Yes, it was a very stable ride.

its more about the rails and most importantly the rails in the tail 1/3. the softer they are the more the water flows around them and holds the tail in the wave, the harder they are the more the water releases of the rail and the more spend and control you will have.
