Parked nearby, Otaki kayaking instructor Wayne Putt also noticed the predicament and solicited the help of Coromandel traveller Peter Jessup, who had two kayaks atop his motorhome, and a rescue mission was soon launched from the beach.
The pair reached Barclay less than a kilometre from the beach, Putt taking the stricken kayak in tow using its paddle and leash, with Barclay, wearing a lifejacket, clinging to the kayak paddled by Jessup as they headed back to the shore.
Putt said he had seen Barclay "go out" and made his move when he realised the kayaker was in the water and waving the paddle.
Barclay said he'd had the kayak several years, and hadn't been aware of the crack in the hull he last used 2-3 weeks ago off Ngawi, on the South Wairarapa coast.
The rescuers said Barclay had done all the right things, having the paddle tethered, having a lifejacket, and sticking with the kayak rather than climbing back aboard.
Jessup said that when he was told of the predicament it became a question of whether he and Putt would go out, or await "the Coastguard" which had also been alerted.
Conditions were described as like a millpond, and all reckoned that Barclay would likely have drifted back ashore – somewhere - if help had not been so near at hand.
"It could have been worse," said Barclay.
