There's a lot of cross-pollination opportunity here, in terms of both materials and procedures. Plus, arborists are, as a group, undoubtedly the healthiest people on the planet, both physically and emotionally. See, they spend their lives taking care of trees. They climb up and around in them, trim off dead or diseased bits, help them grow in healthy directions, just work with them, improving the landscape for everybody. The best place that I know of for an introduction to this world is the catalog for Sherrill and Co., a supply house.
Arborists use a lot of block and tackle and winches, in interesting ways.
They also have a lot to tell sailors about climbing, especially safety aloft. And they are at the cutting edge in terms of knots and splices, too. I hope we can get more of them to show up here.
