does anybody know how many 5 ft lengths of 4inch if would take to float a raft and like, 3 people? i would like to designe a boat around pvc floats.

thats a cool idea. u would probably need a lot i would think maybe like 5 or 6.
U could use less if u pumped them up to like 50 psi.

i dont think more pressure in the floats would give more floating power. then again, i dont know too much about this stuff

i think it would beacause air is less dense than watter so by increasing the pressure of air in the flot u increase the volume of air there for makeing it more boyant

I don't think so, because more air=more weight. Maybe if you used helium lol.

i know that 2x 6"x8' wont hold much more than 90kgs.

ahh, i see that sounds logical. if i can get this thing floating, Ill mount cannons on it and some kind of pneumatic propeller engine.

i think the the weight of the air probably isn't to much of a big deal. the boyancy probably over powers it.

Helium probably would work well, Hydrogen would be even better, just stay away from sparks

lol, the only source of gas i have is a bike pump. i would rather not pressureize them at all. would that be a problem?

the only problem is you always think of things and never start them.

dont pressurize the floats, that makes them more dense and therefore they will have less bowence

yep, its the fatal flaw of having 0-none income

o ok thought maybe it was true.

use plastic 55 gallon drums they arent that hard to get ahold of
