Another question for you oh so knowledgeable folks. The plan I'm using is mostly marine ply for the sides, bottom, transom, etc. But all of the other smaller pieces (benches, seat risers, knees, gunwales, etc) the recommendation is fir. I've looked around and I haven't been able to source any douglas fir locally. Big box stores aren't carrying it and my favorite local lumber mill doesn't have it either. They deal mostly in hardwoods and have a great selection of that, but the only softwood I usually see them carry is white pine. Can you guys recommend any substitute wood for these types of components? I'd like to keep it cheap, but don't want poor quality.
