Mr Lord said misuse of equipment was another problem, and people standing up in their boats then falling over.

Maritime New Zealand safety inspector Alistair Thomson said half of all recreational boating deaths could have been avoided if victims had worn life jackets.
But it was also crucial to carry communications equipment on board a vessel.
"Carry a waterproof hand-held VHF radio or an emergency locator beacon on your person," Mr Thomson said.
Weather conditions and a lack of planning were the other key contributors to recreational boating fatalities, Mr Thomson said.
However, the news is not all bleak. Water Safety New Zealand and its members have achieved considerable success at reducing the drowning death toll since its inception in 1949.
During the past 29 years drowning numbers have fallen 60 per since a record high in 1985 of 215, to a record low of 87 in 2010.
The World Health Organisation found that drowning is the third leading cause of unintentional injury death worldwide, accounting for 7 per cent of all injury-related deaths. An estimated 388,000 people drown each year.
