DIY Aluminum Boat Build

Over the last couple of years I’ve been gearing up with tooling and skills to make my own aluminum boat. I’m finally there with all the design, supplies, welder/push pull gun, plans and the kit that I ordered.

I worked with specialty marine(specmar) to come up with the design for the cabin I wanted so we would be able to over night in it and have a full walk around. The hull is 26x9 with a 22 degree deadrise at the stern. It has a delta pad and a fairly large chine flat. I’m planning on putting twin 200’s on the back.

I used cjm out of Vancouver BC and they were great to work with for the aluminum supply, cutting and bending of all the parts.

I did my first welds on the keel last weekend and can’t wait to get to the actual structure.

More to come and I will be setting the GoPro up for some video and Timelapse stuff. When I get it posted on YouTube I’ll ad a link in this thread.

The hull is the 3129 hull but I sketched up the cabin I wanted and he fit it in to the design. As of right now I’m just shy of 30k after materials and design.

I should be able to work on it some more tomorrow and the next day so I’ll update with some new pics when I get more done.

So this is a complete kit with all the pieces pre cut and formed? Obviously not the gentle curves but where pieces can be sheared and broke they are? Chines? Windows? Hinges/latches? Also with what appears to be some jigs to get the correct angles? Sorry if dumb questions, I’ve never heard of this.

Yeah this is a kit like you described minus windows, latches, and hinges. There are no jigs for this boat, as it’s called a self jigging construction where you use the cross members and longitudinals to form the boat. Everything that could be bent to shape was via a cnc break. It has ink markings on every piece to show locations where other pieces mate up to them and which part number it is.

There is a company in Australia that called cnc marine that is a one stop shop, but most of the places either in the NW or BC sell plans then you go to an aluminum supplier and then they cut, bend, palletize, and ship it. I used specmar, but the other bigger names I found are Cope Marine, and Conrad Yachts. I actually liked the design of the Conrad probably the most but the boat of his I wanted to build was a 29x9.5 which was just to big for me right now.

The Edwing build we did started this same way. Two 22' hull sections with the bends forming the hull and a pile of cut material labeled and stacked on a flatbed. Put this together to make a 'Glider'. Then spend another $65k for engine, controls, and all the finishing parts to make it a boat. Ed sent the files over to the aluminum supplier and they cranked out the kit.

Love build threads! DIY is very cool. At least nobody but you (assuming you don’t tell the better 1/2) can complain about change orders. Hahaha.
