BUILDING A PONTOON BOAT 16 ft need advice :)

[Sceptre]

im not sure if im in the right section but me and my friend desidet to build a pontoon boat we dont know much about boats so were not sure what to make the hulls out of so far we got 3 choises; we can weld aluminium together to form a hull but were not sure how it will work because most hulls are air compressed other method is to take 4-5 barrels and weld them together [and if it will help stuff them with industrial sealing foam the ones they use to make panels with OR we can just use wood and put a fiberglass on top

for the engine we think that using a boat motor would be too easy so were thinking of taking any other small motors [lawn mower, go cart, .....]

the other thing we want to do is to make the deck come appart for easy transportation make it bolt and unbolt in the middle and make the hulls bolt on and bolt off so far were not sure what to use to waterproof and coat it with so any advice would be much appreciated

and all the pictures are just versions and scrap scetches [the propellers supoust to be way lower

Another homemade model - foam?

Build The WizCat 130 pontoon deck boat for under $500

The WizCat is absolutely unsinkable due to solid foam core pontoon catamaran design. The WizCat will not sink or flip over. With it's high floatation and 4" inch draft you can easily slide over those shallow fishing spots.

.................The beauty of this design is you can build it any size you want. You can even build a pontoon houseboat.

Before you spend anything on plans or go off with your own design, wait for a few more opinions. There is something to be said about learning from other's mistakes.

Of course you will always learn more from a failure of your own.

This gets an "A" for the "Cool" factor.

Construction:

The MODULAR BOAT is constructed from a space lattice system of stainless acid resistant steel (see "Manual for N55 SPACEFRAME"), which combines optimal strength with low weight. Tetrahedral and octahedral polyethylene tanks are used for constructing the floats including the stem. Half-octahedral tanks are built into the deck that connects the two floats. In combination with polycarbonate lids, they provide flexible space for different functions and items: ladder, anchor, seats, tables, stowage, compass, battery containers, etc. These functions can be fastened and moved around as desired.
With the addition of a rigid deck, the MODULAR BOAT can function as a pontoon bridge, or as a floating platform for various constructions on water. The size of the MODULAR BOAT can easily be adapted to one's requirements. The number of plastic tanks in the floats may be varied, but it is necessary to secure sufficient buoyancy for the planned tasks.

Lots of weird plans at that site.

Do a forum search, plus I know there is information in the links I posted.

Also look in this part of the forum:
