Auckland man Wayne Dil is changing the face of human aid around the world with his latest invention - the UFO Rocket 2 in 1.

Mr Dil owns Universal Food Oven which already has a range of portable, stainless steel food ovens.

However, his latest creation - one of many on display at this weekend's Hutchilco New Zealand Boat Show - he says is the first in the world that can boil 12 litres of water and cook food at the same time.

"So it's cutting down on fuel and it's cutting down on time ... and runs on sticks, coconut shells, corn husks or charcoal so it will run on just about anything."

Mr Dil said it was a bit bigger than a bucket so it could easily be picked up and carried to a water source.

"We've just come back from Cyclone Pam in Vanuatu and did a donation over there and just got an order for a 1000 units for Vanuatu from the Red Cross, Save The Children and World Vision."

He will travel with Civil Defence NZ to Nepal on Monday to deliver more of the ovens.

Other new gadgets on show include a new GPS plotter and fish finder - NavNet TZ2 - by New Furuno electronics

"It can measure the size of the fish as you go over the top of it, so as you're driving along you can technically see on the screen the estimated length of the fish," sales engineer Nick Fogarty said.

"So it helps you to target the bigger fish."

It also showed the composition of the sea floor - mud, rock or sand - and its resolution was eight times better than any other sounder on the market. It retails for $2500.

The company had also developed the world's first autopilot system, the Sabiki mode for its NAVpilot, that worked in reverse.

For the speed lovers, over at Rayglass boats they're displaying Mercury's new 400hp supercharged outboards - the first on the market outside of the United States.

Rayglass sales director Scott Little said two of the engines were sitting on their Protector boat - the only boat in the country rated to handle 800hp.

Paul Grey at Aqua Sinka has developed the world's first non-toxic, lead free sinkers.

Made out of iron sand they've been soaked in berley so it not only attracted fish but saved fishermen from having to buy their own berley.

Over at Invercargill boat manufacturer Stabicraft, they're displaying the world's first carbon composite boat.

Project manager Daniel Upperton said using carbon meant they had more flexibility in the boat's design and were able to manufacture them a lot quicker.

Marine distributors Lusty and Blundell have Raymarine's fish finder the Wi-Fish and Wi-Fish app.

It's targeted for those who don't own a GPS and more for day fisherman or those that use "the tinny".

The app means the fish were displayed on the fishermen's smartphone.

Also featured is Ocean Signal's new 18.5cm length digital distress flare which was the first to be able to be seen 360 degrees and have a 10-year battery life.

"Its size brings this in the market for hunters, trampers, boaties, police, anyone who has to signal people to let them know they're there," Lusty and Blundell's electronics product manager Bob Fassio said.
