Quintrex Plate Boat Construction - 7600HT Yellowfin

Quintrex Yellowfin plate boats are built seriously tough!
Watch the extensive construction process with over 80hrs of welding in each 7600HT Yellowfin model!
Built here in Australia with 6mm bottom sheets, 4mm side sheets and an internal 'Marine Core' rib structure armoured hull to ensure strength, our Yellowfin range has all the features to suit the true bluewater fisherman.

That is the best production method, moving the piece being welded and keeping the welder stationary and comfortable. Gives me ideas !

[@ianmoone2359]

Probably about 3 or 4 90 pound bottles of Argon shielding gas, probably 4 or 5 kms of alloy welding wire, so 2 miles of wire? That’s based on welding up a 16ft v nosed punt once about 15-20 years ago.

[@clintpuddister7257]

A quarter mile or more maybe

[@m.thansen5738]

3 to 4 4.5 kg rolls of 1.2 wire and about 2 1/2 big bottles argon at 20 lpm thats for a 24 ft 5mm bottom 4mm sides 3mm cabin boat

[@jamescampbell9992]

With its full interlocking stringers and ribs. On the quintrex I can't believe they weld the bottom sheets first, flip it then weld like individual piece stringers by hand placement between the ribs.

[@vagusnerve8797]

Hellow bro. I wanna make my own aluminium boat. What aluminium sheet thickness and alloy is better for making hull?

[@robertlackey7212]

5086 , in boat building scantlings are used , which basically means you go and look at as many boats as you can , and make a educated guess , bigger boats tend to use thicker material , boats that see rougher service tend to use thicker material , you need to be careful about not making abrupt transitions from something very stiff to something more flexible imagine that you were a giant and you grabbed the boat and started twisting and bending it , now imagine where it would crack , those are the places you need to pay a lot of attention to .

[@andrewiannello6548]

Where's the floatation? Relying on air lock once the floors down. What if you get a hole, she sinks?

[@clintpuddister7257]

All boat sink if they get a hole . the way boats work is by displacing more water than the weight of the boat . this boat may weigh 2 ton but displace 4 to 5 ton of water weight .

[@andrewiannello6548]

@@clintpuddister7257 incorrect, level floatation if done right allows you to bail out and get going again. PU closed cell foam filled cavities do not allow water to enter the hull even with a hole.

No respirators, turn a solid into a gas then inhale it cool and turns back into a solid. Boycott that boat builder until they start treating there staff properly

Main welder did but the apprentice had disposables. Likely the main welder probably bought his own adflo system. I agree there shit heads for not sorting out the apprentice

[@andrewiannello6548]

Still no foam. What a joke. Only meets Inland rivers. Wonder what BS weight you'll stamp on it. Only recently i borrowed a hornet trophy 435, i had some concerns and ended up weighing it at 514kg with no fuel. Supposedly you can put 4 people /400kg in it! By my calculations you would be lucky to have one person with gear or two people without even a fishing rod. So if i took the manufacturer weight and tried to tow this with a Hyundai, cause supposedly your within limits, then have an accident and have everything weighed to find out your over weight! The early hornet I tested wouldn't even meet basic floatation and would sink. I don't actually think Quintrex knows how to perform displacement calculations. When the boats are unbalanced then your centre of bouancy shifts, you guys don't design this in. You only need year 11 physics to work it out. I worked this out after putting my family in this boat with gear at 270kg. We had water lapping in at the top sump plug. We shifted weight forward and slightly improved but not enough for me to launch off the Jetty. I took my family out of the boat and put it back on the trailer. And went and performed my own calculations as described above. These things are a death trap, especially in tropical waters with crocs and large tidal systems up north. I wouldn't by an aluminium boat with a short shaft, the displacement can never meet the design loads with any safety factor greater than 2. Basic floatation safety factor is 5. I'm extremely disappointed that my life and that of my families was compromised because I trusted the build plate. Please anyone reading, make your kids finish year 12, maths & physics is important.
