The 14th Riviera Port Lincoln Tuna Classic Invited 23 boats with crew to compete in the 10-kilogram line class competition, which was established to shine a light on sustainable fishing practices. It is a catch-and-release event that targets only southern bluefin tuna and is the first of its kind in Australia to disallow three-pronged fishing hooks.

It was a mix of local knowledge and a sense of adventure by two skippers that saw them haul in the major trophies, including a record $37,080 cheque for the heaviest fish as part of the Calcutta bid.

At the shotgun start, skipper David Buckland decided to hang back before taking off east towards Roslyn Shoal as most vessels headed full throttle west.

The move paid off and earned Buckland a back-to-back win for Overall Champion Boat with 45 fish caught on his Riviera 51 Longshot.

"It was a chance and it paid off," Buckland said.

"We knew there were tuna elsewhere, but I'd been out to Roslyn Shoal the year before and done well there. I thought a few more boats would have followed us this year, but for a while we were only three."

Within minutes they'd worked out what lures the tuna were biting.

"We put out four lines and started getting them hand over fist," Buckland said.

Longshot's crew also listed individual wins, with Emma Forster earning Champion Female with five catches and Tom Pietch taking Runner up Male with 17 catches.

Longshot is the beloved fishing vessel of the late Ron Forster, who passed in August last year. He was a founding member of the Tuna Classic and a perpetual trophy has been created in his honour.

"Ron was an avid fisherman and his boat has been set up for fishing. We went out in his honour and it was a fantastic weekend," Buckland said.

"It was great to get away for a couple of days given everything that's been going on. The best place to be is on a Riviera out at sea."

A total of 145 fish were caught and released across the weekend.

Weighing in at 15.8kg, it was Gilbert Le Brun's bluefin caught on Laila Jane that won the Calcutta and secured $37,080 for himself and the crew on the Riviera 525 SUV.

Like Buckland, Laila Jane's skipper Mark Waller decided to take a risk and not follow the rest of the fleet.

"We could've ended up with absolutely nothing and just been out there catching whiting," Waller said.

"It took us a good half an hour going backwards and forwards before all of a sudden we ran over some fish and away we went."

Laila Jane also won First Fish Caught, Runner Up Boat with 36 fish, and had aboard Champion Male Ian Montgomery. with 19 fish. He earned himself the first Ron Forster Champion Angler Perpetual Trophy.

"We were quite shocked at the trophy presentation; it was nearly a clean sweep. That's fishing," Waller said.

"Right spot at the right time. We just got lucky."

NSW Maritime acting executive director Alex Barrell says the NSW Government will install a new pontoon at the Carrington boat ramp to improve boating access to Throsby Creek.

"Boating is a popular pastime in the Hunter region and installing a pontoon attached to the Carrington boat ramp will make the facility much easier to launch and retrieve vessels," Mr Barrell said.

"Boaties will now be able to tie their boat up to the pontoon while they park or retrieve their trailer."

Work is expected to start in August and will take six weeks with the ramp to be closed for about two weeks, weather and sea conditions permitting.

Whittley Boats will introduce an outboard-engine version of the Whittley CR 2600. The updated model was due to debut at this year's Sanctuary Cove International Boat Show.

"The new CR 2600 OB we feel is the ideal Queensland family fun machine and provides the perfect platform to launch into summer post social isolation," Laurie Jackson, sales manager at Whittley Gold Coast Sales, says.

In images teased on their Facebook page, it appears that the new model will come with a 200hp Yamaha F200 four-stroke outboard engine.

It includes all the features of a the stern-drive Whittley CR 2600, and can be optioned with a bow thruster, Fusion audio system, Zipwake trim tabs and a cockpit table.
