I've been looking at a Site where it's claimed that the natural aluminum
produces an oxide to protec it's self but the paint interferes with that process.
Anyway I'll let y'all experts debate that.
I dug out my 2012 Legend boat catalogue and it boasts of. 100" or 2.5mm
thick 5052 H34 cold rolled aluminum on both hull and sides.
The nearest Canadian competition (Princecraft Holiday WC) uses H36
aluminum, .090 or 2.3mm on the hull and. 072 or 1.8mm on the sides.
Legend claims their's is stronger because it's both thicker and more flexible.
Princecraft claim their's is stronger because it's a harder metal.
I'll let the resident experts decided who's right...I believed Legend two years ago.
Sounds like what my Harris is made of. Newer pontoon boats use .090 or
even .080 on the log with .10 for the nose cone, if it is a premium
model.
And my Jetcraft is stronger. 5061 3/16" thick.
