Need Help for Airplane Potoon Boat

I am thinking of building a boat from an airplane pontoon. The pontoon is designed to hold about 750 kg and is about 16 ft long by 2.5 feet high and 2 feet wide.
I like it cause it is free, has 5 plus usable capartments that are individually sealed, very lightweight alum and is designed to plane when power is applied so I think I can get buy with a small outboard.

My idea is to run 2.5 to 3 inch pipe thru the pontoon where the struts from the plane mounted. This is easy and strong with some bolts and brackets I can rig.
One front and back and I've got the outriggers. Thinking of using 3 4 or 6 inch PVC pipe on each side for the outriggers. A deck of alum diamond plate 4 by 8 ft seems to fit well.

Any reasons I shouldn't go ahead with this?

 

no .....

 

If I get this right the pontoon is only 2 foot wide and 2.5 feet high?---so its higher than wide?.

This has no stability at all, a 8x4 ally pate as a deck is ridiculous.

This pontoon was used in pairs making it stability completely different.

They also have a massive rocker allowing the aircraft to "rotate" for take off.

 

thanks

Yeah, it is about 2.5 ft "high" in the mid section tapering off to about 6 inches at the rear and pointed at the nose. One reason I think it could work is that is roughly the design of all the locals boats.... most are a dug out log bottom with planks attached going up in a V... 3 feet high by about 2 feet wide, then outriggers on both sides. They have a couple hundred years of using em and they seem to work pretty good but they are very heavy and use a lot of fuel/power to make em go. I like the light weight alum option....
I have a number of purposes in mind, one is for surf trips so I like the rocker in that I have something small that I can take into surf conditions... hopefully surfing with the board and not the boat but this would make it do a little better in rough water is my assumption? The local boats have a really high bow for this purpose but I thought with the rocker and sealed compartments I might be achieving the same goal?

what would you recommend for deck that is lightweight?
I am pretty limited in terms of materials that are available especially since I am trying to build it 50 miles on a dirt road (4-9) hours by 4x4 from the nearest town which is air access only at 5,000 feet. There is a heck of a lot of wood but that is fairly heavy....?

thanks.

 

Well if you intend to put riggers on it then thats different. Sorry, I read your post and you do say outriggers.

I thought you meant on its own when really it would just turn over like a log.

 

thanks

thanks for the word, so far I am getting nothing so a little leery to go ahead. My aussie friends here compare me to an "aussie bush mechanic" all the time so maybe that is why you are more positive! You don't live that far away and aussies are a whole lot better at innovation and using what is laying around than most americans! americans just go buy a new one for $500,000but being an american I can get away with saying that!

 

Sorry Scott Im a pom,--but I have been to Auss.

Its not a quick service but hang about a minute. I think you will have some stuff in the morning. The ******* are still in bed.

 

Could you tie the 2 pontoons together and put 2 small engines inside the pontoons, along with 2 rudders. Have some sort of seat between the 2 pontoons, then your off.

I as an American dont buy what ever I want, I make it most of the time because its to expensive.

 

Thanks. I guess?

For me expensive is anything over $50 though. I'm just 15.
