older hulls you can:
leave on a trailer for years without the fear of the rollers pushing the bottom in.
you can drill just about anywhere and only need washers to back up the bolt...not alum. plating or starboard or wood.
the sides don't flex like tin and won't spider crack.
punch a hole in anywhere and you have some meat that surrounds that hole to work with/repair.
they can take a pounding and keep on going.
I've seen half the bottom taken off of an older 23 seacraft by a floating log and it came home from offshore safe and sound[thick hull] wouldn't want to try that with a new boat / thin new an approved resin's.
