Totally crucial, bro! More volume (width, thickness, length) equals more float and easier paddling. A high-volume board gets you planning quickly and is stable. But once you’re skilled, a lower-volume, more refined shape paddles through the water more efficiently, letting you duck dive easier and position yourself precisely. It’s a trade-off: float helps beginners, while performance shapes demand stronger technique. Choose a board that matches your skill and the waves you’re chasing.
