Eureka Canoe in Standard U.S. Lumber Sizes

Hello All,

I've searched the site and can't find that anyone has posted the U.S. lumber equivalents for the BoM. Plywood is 1/4 inch, but after doing a simple metric to imperial conversion, I doubt I'll find lumber in 1.8" x 0.6" on the shelf at my local lumber yard. I haven't the facility for ripping, so I'm hoping someone has worked out the U.S. standard lumber sizes to use.

Thanks!

Richard
