Time laps hand cut ally boat build

My across the road neighbour has built a few boats from flat sheet, his method is exactly the same, but, he did it all on his own, except for some difficult lifting jobs, then I helped him.

Good old George up to his old tricks again is he....wouldnt touch a Samaurai boat with a 10 foot pole...bloke runs his businesses on government grants and indigenous loans which in the past he doesnt bother paying back....

As well as going bankrupt he also faced criminal charges for fraud..

He builds them in Ingham ..there is a couple running around here which only have about a 15 degree deadrise at the back which is certainly not ideal in the FNQ chop..seems to be a case of an out of state resident not understanding local conditions or just not caring..

That T top failed in it's first couple of weeks - cracked left right & center :o

I did not put the link up to promote the boat only to show everyone how easy it was to form the hull,I’m not buying one, I just thought it was interesting watching it being built in time laps.

To be brutally frank , that is the worst way to build an aluminium hull. Certainly the easiest. But no guarantee of getting a straight one. Reading the op, I thought he was referring to a more traditional way of construction, which is to cut all the frames, align them in a jig, then weld the sheet to it. Measuring and checking all the while. This lofting technique was the traditional way of building timber boats, and is applicable to aluminium.
With his method, you are relying solely on all the template cut bits to align, and effectively using that to confirm that the whole thing is shaped as it should be. Sorta works, in a cheap and nasty sense.
And to finish, referring to any of these sorts of boats as " plate" is incorrect. The definition of plate with aluminium is in excess of 6mm, go ask any supplier.
You can henceforth refer to them as " sheeties " - although, in his case sounds like a couple of e's need to be replaced with an i. -:)

There is a local builder which I was interested in and he was reasonably priced, I noticed on my first visit pallets of CNC ally and watched a few boats being worked on in the finishing stages abd thought that was fine. Next visit I watched as 2 workers just pulled sheets together and another started welding them on, no jigs just depending on the CNC sheets. I didn't go ahead with the purchase based on what I saw, just wasn't confident in getting a straight vessel.

Seemed easy getting the hull togeather.

Would have been a lot of hours gone into that. A lot of welding.
The trailer seemed a bit over complicated.

I can not understand why they opt for hand cut these days?
It is inaccurate and certainly not cost effective when compared to either CNC router cut or laser cut.

The method they use can produce a straight hull IF they take care on the cutting and the assembly methods....it is easy to screw up though.
1mm out at one point can put you 10mm out a metre down the track.

Laser cut with index points for stations is the safest.
I also like to see the keel running between the bottom sheets with 4 continuous fillet welds at that joint....then a half round over the keel to further support the keel to bottom plates stresses.
