A PWC rider does tight circles 100 metres from a shoreline where several houses are visible from the water, but the area is not officially marked as a restriction zone. Have they broken the law?

1. No, because only officially marked restriction zones carry this rule
2. Yes — the irregular-driving-within-200m rule applies anywhere dwellings are visible within 200m of the shore, even outside marked zones
3. No, because circles are only banned during tow-in surfing
4. Yes, but only if it happens after sunset
