"It's really rugged out there and it's really dangerous right now," he said.
One of the boats was a 9m blue-and-white launch known as Eagle and the other was a 11m yacht called Te Hani. Neither appeared to have been damaged.
The boats would not be moved until high tide, about 1pm today, Mr Isherwood said.
The Tauranga Coastguard was called to the aid of a boatie who got into strife while checking his mooring yesterday.
Rescue-boat skipper Peter Donaldson said the man had rowed his dinghy out to where his boat was moored off The Strand but a gust of wind flipped his dinghy while he was onboard the launch.
The dinghy partially sunk so the Coastguard was called to pick up the man and tow his dinghy back to sure, he said.
Fire service Northern Communications Centre shift manager Jaron Phillips said firefighters had been called to about 100 wind-related jobs throughout the Bay of Plenty and Waikato yesterday. In the Western Bay, firefighters had attended about 30 weather-related call-outs.
"There's been power lines down, trees bringing power lines down, trees down across roads, tile off roofs, garden sheds blowing over," he said. "Nothing's caused any injury or anything."
Among the calls Tauranga firefighters attended was trees on a power line on Kaitemako Rd and a broken power pole at a 14th Ave intersection.
A photographer at Pilot Bay reported being pelted by sand as he struggled to walk against the wind. The north-bound lane on the Elizabeth St off-ramp was closed for about two hours from 5.30pm while contractors tried to secure a street lamp loosened by the wind. The MetService predicted the wind would continue to drop today.
