It was more difficult than they expected due to strong currents but they made it to land and raised the alarm at a house at Tapeka.
Their only injuries were a few scratches, Gorrie said.
''I don't think they were powering through. If they were going at speed anything could've happened, broken limbs or worse.''
A dog on board also ended up in the water. The men had decided to put on the dog's lifejacket a short time earlier as they were passing the Black Rocks.
It is believed the dog also made it safely to shore.
The aluminium boat did not sink but was still drifting upside-down off Tapeka Pt, where it posed a navigation hazard, on Friday morning.
It was retrieved by the harbourmaster and towed to Waitangi, where the father of one of the young men collected it.
Harbourmaster Jim Lyle said the young men were ''extremely lucky''.
''We've had lots of cases where people have been really badly injured, with legs broken, faces smashed into the boat or knocked unconscious, by hitting rocks in the dark.''
He urged anyone driving a boat after dark to reduce speed near shore or if they weren't certain of their position.
Gorrie said Tapeka Pt had been the scene of many boating accidents over the years.
