Fines totalling $3600 have been issued to Bay boaties breaching rules in Tauranga Harbour this summer.
Bay of Plenty Regional Council's Tauranga Harbourmaster issued 18 infringement notices incurring $200 each between December 1, 2014, and January 18 this year. Nine involved people breaching 5 knots within 200m of the shoreline.
Thirty-one warnings were also issued for the same reason, or not wearing a lifejacket while being towed and not having an observer while water-skiing.
The fines also did not include 11 breaches of the Rena shipwreck exclusion zone for which offenders received warnings.
Dan Carr, who runs Get Wet Jetski Adventures hire at Pilot Bay, said he saw people breaching the 5-knot rule all the time and believed it arose from people's ignorance rather than arrogance.
