Why custom helps
Most surfers do not need a more “performance” board. They need a board that stops fighting them.
San Diego surf can look fun from the parking lot and still ask a lot from the wrong shape once you are paddling. That is the gap a custom board closes. It gives you more useful paddle power, cleaner glide through flat sections, and a shape that makes average days feel more alive.
That does not mean giant oversized foam. It means picking the right length, width, thickness, rocker, bottom contour, and fin setup for the conditions you actually surf, not the conditions you wish you surfed every day.
