Bay of Plenty Harbourmaster Peter Buell is warning boaties to steer well clear of large vessels as summer approaches and numbers increase on the region's waters.

And while it seems straightforward enough advice, the best way to avoid collisions with merchant ships is to get out of the way and quickly.

However, some pilots continue to find themselves in tough situations, with some boats getting in the way.

To avoid potential collisions Peter is asking that boaties not to cross ahead of vessels unless it's clear by at least 500 metres, and to always give way.

'We share our waterways with a wide variety of commercial and recreational boats that vary hugely in size,” he says.

'For the most part this works well, but increasingly pilots of larger ships are finding boaties are not paying attention and are getting in the way.

'They are not able to stop or change course easily and often cannot see you.

'Boaties need to remain alert and take the time to understand their needs.”

He also urges boaties to check out the Port of Tauranga shipping information schedules on their website before heading out, and to listen to channel 12 for shipping movements.

Boaties should also visit their regional council office to collect a Boating in the Bay of Plenty booklet as an up-to-date resource that captures local rules and how to stay safe on the water.
