A man dislocated his shoulder when an aluminium open boat rolled on the Maketu bar on Sunday afternoon.

The 3-4 metre outboard powered tinny rolled as it was returning over the bar.

The Maketu sand bar was the scene of a boat rolling on Sunday.

'It looks like they have hit the sand bar and a wave's rolled them,” says Shane Beech of the Maketu Volunteer Coastguard.

'They have been chucked out and I think the boat rolled on his shoulder or something and dislocated his shoulder.

'They were pretty lucky it was so shallow, probably the deepest area would have been up to their waist.”

The men, a local and a visitor, went ashore on the spit across from Maketu. The men aged in their 30s were returned to the mainland where the hurt man received medical attention.

'They just mucked it up coming in over the bar basically, the boat's washed up a couple of hundred metres down the beach,” says Shane.

'The Coastguard guys retrieved it and their gear.”

Tauranga Volunteer Coastguard had two calls over the weekend.

On Saturday there was a boat with a flat battery, on Sunday it was a boat with broken steering. Both craft were outside the harbour, but on the shore side of A beacon.
