FINALLY, it's my turn to post a FROG photo.
Many thanks to everyone that posted photos. the pics were very helpful during throughout my build.
FWIW: okume 12mm ply, cedar 4"x4"x10' ripped into stringers (scarfed using Titebond 3), "Tandy" brand polyester flat artificial sinew, laminated oak coaming (1.25" tall with .5"x.5" lip), 28 lbs with coaming and foot braces.
Thanks, guys. Greendane, the trailer is a Karavan. I see there is a dealer in Tacoma. Let me know if you're looking for more info. This was the lightest model.
