Aluminium is dangerous in salt environments and heavy loads. Fine for a
mast. But there is no way I would tow a 1 ton boat on one of those
trailers things. It stresses under extreme loads and will give way
without warning. Imagine a trailer giving up on the freeway. How many
people would you like to kill?

One may be ok to tow an inflatable. But forget it for a serious sal****er
boat.

Nonsense. Properly designed and manufactured an aluminum trailer is every
bit as strong or stronger than a galvanized steel trailer and it won't
rust.

Yes.. ever seen a stress fracture give way on a gal trailer? No? didn't
think so. Stress fractures in Alloy will snap open at whim. Particularly,
as I mentioned, ones created in a salt water environment. They are insidious
and not always visible as they may occur inside the frame or even at the
welds.

Rust on the other hand is usually visible and leaves tell tale signs of its
existence by way of well know stains leeching through the protective
surface.

I know aluminium is strong. Its a great product. Just not in trailers
designed for heavy loads. If that were the case every semi trailer rig on
the road would be alloy to initiate fuel savings and assist with easier
breaking and accelerating. But no, they are steel- they aren't even put in
and out of salt water.
