Wes Freshour - boat repair and paint (not a lot of reviews yet - as of 4/2020, but first ones are very positive on quality and cost (did work on Ana Swetish's ski). Wes seems to currently have a pretty small business so repair may take some time…)
Tom Swetish designer/maker (made custom SUPs in the past). When he is not inventing patented boating accessories or consulting with large businesses he might have time to make a custom part (3-D printing also) that you otherwise cannot find or replace if he has the time?
