Aluminum Duck Boat Build

Postby Tanner01 » Sun Sep 02, 2012 10:13 am

I posted a while back that I was building a sneak boat out of aluminum. I finished that one and decided that I could improve on it so I gave the first one to the guy I hunt with and started boat # two. I made some changes by adding some storage and some additional storage in the back.

You done good. Looks very well thought out. Only thing you need now is a photo of it with ducks on the deck.

The original design started off as a popular mechanics article from the 50's.
The finished specs on it are as follows 12' long x 44" wide. The boat weighs approx. 128 lbs. It is at the maximum weight that one guy can handle in and out of the truck bed by himself. It is heavy
I installed 4lb two part foam in the front and the rear. I used 1/4" plywood for the deck floor and installed the 1" blue foam board under that. I used the Cabelas brand of rubberized skid resistant paint for the floor and the storage lid for traction. Fully swamped this boat should not sink.
A double paddle moves this thing real easy once it starts to go. I used a push pole for the shallow areas and had no issues getting to where I wanted to go. The motor is a 3.5 HP and is fine for this thing.

Finished the layout blind for it last week. Found a blind in the cave at Cabelas and modified it to work with the boat. I am going to paint the motor.

So I am very happy with the boat and have been using it for fishing while daydreaming about duck hunting. I kept thinking it may be great for the marsh but a little small for the river during the winter and I would like to try some bigger water. Because the planning and layout took me so long to do I decided it would be better to build a new bigger boat from a set of real plans. (It is already Sept) Also the boat I made is not a planning hull design. I have no clue how to make a boat with a planning hull so I went online and decided after talking with Sam Devlin that I would order his BB3 boat plans and give the bigger boat a try. I did initially talk to him about designing a boat for me but his thought was why pay for a design and reinvent the wheel when what I was describing to him was the BB3. There where a few things that I did not exactly like and so I changed them as I have been going along.

Oh very important note to anyone who wants to convert plywood to aluminum. Stitch and glue tolerances are very liberal and generous, you don't want to try and fill the gaps that those plans will leave you with so you have to either fit everything or adjust all of the parts prior to building.

changed the cockpit size and made it easy to fabricate, though I did spend a couple of hours figuring out how to curve the top part I ended up opting for the most space. I believe his drawing was more aesthetically pleasing but we are building this for more space not less.

Excellent fabrication work. I was a tig welder in a factory setting for a while, and you sir pay attention to what you're doing. I'd like to see more of the big boat build. Way to go! :thumbsup:

Kind words but I only post the good photos not all of my mistakes. :lol3: And I get to use a pulse mig welder that that helps with my welding skills. I am not a welder by trade but I can use a grinder better than most. I screw up I grind it down, back chip and do it again. Some days more grinding than welding.

I have a spool gun for my miller. I would like to weld a gun box and steering console and front deck up for my 16 ft mod v. I have to practice more first before i even dare burn a big hole in my hull. Aluminum is whole different creature than steel!!
Its looking awesome!! :thumbsup: :hammer: :grooving:

I put the fuel tank in the front of the boat to help balance the weight out

I am adding a lot of foam to the boat. 2 part 4lb density in the front bow area and then in the rear section. In addition to that I am using plywood for the floor with 1" foam board underneath. Between all of the foam the watertight bulkhead and the storage bins I should have no worries with my welded seams :no:

One thing I did learn the two part foam will ignite while welding and the bed liner coating will dissolve the pink foam board almost instantly.

cwa1104sab - 1/8" thickness for most of it. I had to redo a couple of the bulkheads and changed things as I was going so I ran short and was cheap about ordering more and used left over .090 for the bow deck. Wished I hadn't because it has a slight wave to it and it was hard to fair the side to it and weld the different thickness aluminum (with the expanding foam under the bow deck it feels solid as a rock, just not the perfect look I want). 5052-H32 which might be considered soft by some standards but it is easy to weld and work with and seems not to be brittle at all.

Tested the boat out had to see how it floats.
Still have a few things to finish up on it.
The boat floated perfect and might only draft about 6" give or take with a light load, pretty good far a V-Hull
Used the 3.5 HP and it was easy to get to displacement speed but the river is running slow.
I ended up plugging the motor up and blocking the intake with weeds, this caused the water pump impeller to melt. $45.00 in parts to fix, not the first time.
I was planning on a 20 HP short shaft after finding out that the 25 HP jet was 16 weeks from the factory to get.
Now with the problem with the weeds I was rethinking what might be best for this boat.
I need to handle the river during the winter to get to where I want to go but I want to go where others wont or cant go, maybe a surface drive like a copperhead or maybe a smaller motor and forget about planning speed.
Any suggestions

Might have to sell one The closer to finishing I get the more I am thinking about the next one :fingerhead:

I think a 10-12hp Copperhead or a similar equivalent would be perfect for what you're describing. I have the 12hp model and have been very pleased with its performance.

What kind of noise or vibration with a motor like that.
