RE: ali woodie?
i dont think it would be heavy but welding thin ali is imposable and if you used thicker alli that you could weld that would prob make it heavy but weather it would be heaver that a wood one you will have to make it to fund out
but its worth a try would be an intersting project
keep us posted

RE: ali woodie?
it will be heavier for the reasons you just mentioned if it was a good idea i think wed have seen a few built before now? 
.ive seen a few ali airboats built and they all ended up HEAVY!!.

you could do it with out needing to weld anythng just use .5 or 1mm ali sheet and then use a cold weld type glue to bond it all together that would work i might try it my self one day when ive finished all my other projects

RE: ali woodie?
he said he'd rivit it all together apart from the bit of the hull in contact with the water, which he'd glue or something similar.
but i would think thin ali wouldnt weigh more than ply covered with epoxy
his idea, not mine

RE: ali woodie?
it might work if its glued and he keeps the frames inside to a minimum,not sure about gluing ali its not my thing to be honest but one thing that could be a problem is dents .the rivets would look awfull though [:'(].

RE: ali woodie?
i say go for it,
why not try something different then he can tell us if it works,
i dont see why thin ali sheet bonded together wouldn't work, they build real boats out of it.
i also thought about doing it from thin steel sheet if its well protected ie by powdercoating it would work.
just cos its different doesn't make it wrong (wait till you see mine the drive and rudder is nothing like anything ive seen but i like trying new stuff, it would be a dull world if everything was the same.
go on do it, [sm=thumbup.gif]

RE: ali woodie?
It could be joined by flush rivets, sealed at the time of rivetting then any protruding rivet flattened when the seal has gone off.
If the plate were thin enough the weight could be controlled. I am not convinced it will be any stronger than a good carbon / kevlar boat though.
Thinking on, a good aluminium welder should be able join thin sheet too.
Interesting.
