Speed will not only be targeted on the road this summer.

BOP Regional Council Maritime Operations Manager Reuben Fraser says people come to the bay from around the country to enjoy water-based activities - the large increase of people means waterways can get crowded.

'The rules are there to keep everyone safe so we would like to think that people will abide by them and support the work of our staff and volunteers this summer,” Reuben says.

'We ask that people behave responsibly and take extra care when it gets busy."

Divers are reminded that they must have a dive flag visible on board their vessel and boaties who see vessels bearing these flags should stay well clear, as divers often drift away from their boats, says Reuben.

People are also being urged to ensure inflatable life jackets are in good working order.

'Regular maintenance of inflatable life jackets is essential - they are light, easy to wear and don't take up much vessel storage space, it's really important that they are checked regularly,” says Reuben.

'We hope people will have a fun and safe festive season.”

The rules

- You must be 15 or older to drive a powered vessel that is capable of travelling faster than 10 knots, including a jet ski.

- You must not go faster than five knots within 50 metres of another vessel or person in the water, also within 200 metres of the shore, a dive flag, or any structure.

- The operator of any vessel, including a jet ski, must ensure there is a lifejacket of the correct size and fit for each person on board.

- You must ensure that your vessel's wake does not cause danger or damage to boats or other water users.

- If you are skiing/towing there must also be an observer who is older than 10 years in the vessel or on the jet ski. The person being towed must wear a lifejacket.

- You can be fined $200 for breaching the bylaw.
