Paddeling for a wave

Hi
I am so stuck with my surfing. Its my paddeling i just cant build up enough speed. My friends are sitting right next to me and all they have to do is 3 simple strokes and there on the wave while I have to paddle so hard to keep up with them. Its the same paddling out the back as well they are paddling so easy and i have to paddle twice as hard just to keep up with them. I think its my paddling skill but it also might be my board. Because I just bought a new board and its a bit bigger and a lot narrower than my last board. So this might also be a problem. On my old board i could catch the waves no problem and do a bottom turn and other stuff. But ever since i got this board i cant catch any waves its anoying.
Any help would be appreciated thanks
