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.

What are you planning on using for a float? If you are using styrofoam
(bead board) you can just glue AC plywood to the top, wrap a canvas
skirt around it to shield it from sunlight, and hang lath lattice off
the sides to protect the foam, or maybe hang 2x8 boat bumpers. You
might build a ladder or two for the swimmers, and screw some cleats to
the plywood for the boaters.
