Thirteen children were among 79 people in the Bay of Plenty caught not wearing lifejackets as they headed out to sea this summer.
The Bay of Plenty Regional Council surveyed 259 vessels and occupants at boat ramps across the region from December 26 last year to February 6.
Of the 638 adults and 124 children surveyed, 66 adults and 13 children were not wearing lifejackets. When asked why, eight people said they did not think there was a risk, five said lifejackets were too expensive and three said they were uncomfortable.
Others said lifejackets were "uncool" or they had confidence in the skipper's abilities.
The survey results showed 11 of the vessels checked did not have any form of communication on board and 16 boaties reported not having checked the marine weather before heading out.
