One can build good aluminum boats in sizes even smaller than that, as is evidenced among my small pram designs. on cost. the aluminum to build a bare hull costs just under twice as much as the mild steel to build the same design. but aluminum is faster to work with, so the savings in labor helps even the score.. Which is better, steel boat hulls or aluminium boat hulls? this is a difficult question to answer definitivly, as the choice of aluminium vs. steel completely depends on the design of the boat and what it is largely used for.. Material used: many pennies (sets of 5) 12" by 12" aluminum foil container filled with water to construct the boat: i hand folded the 12" by 12" aluminum foil it carried 113 pennies before sinking.
