What happens with a skim board that is to big?

A skimboard that is too big can be challenging to maneuver and control, making it difficult for the rider to perform tricks or maintain balance. It may also lead to increased drag in the water, causing slower speeds and reduced performance. Additionally, an oversized board can create a higher risk of injury, as it may be harder to recover from falls or unexpected movements. Overall, using a properly sized skimboard is essential for optimal enjoyment and safety.
