Call yourself a bushcrafter? I know where there is some lovely thick hazel that could do with coming down, and you could make a proper frame that wouldn't rust or mark your canoe. I can give you a pointer if you need it, but keep it under your hat as it is quite a good stand yet is totally overlooked and I want it to pretty much remain that way! I'd certainly take you in and show you where it is though and even help you lug it out!
