Need to build a new dock. Old one is just about done.
It'll be a floater like the old one.
The question is wheather pressure treated wood or
cedar is better. The problem with pressure treated is the arsnic
content. For a dock that swimmers and skiers will be sitting on and
pulling themselves up on, that's not so good. Cannot always get
pressure treated without arsnic.
How well does cedar hold up to extreme weather condiitions.
Fresh water, Canadian winters and all that.

I have never built a dock so can't speak directly to that but have had
splinters from both CCA and cedar (arsenic is no longer used for
pressure treating in the US). The cedar splinters (IMO) are a real
bitch compared to pine. Either way I suggest you use a good marine
finish on whatever you choose. Several coats of marine paint or
varnish would reduce splintering.

Have you considered using cypress?
