Zach-
I have a hard/epoxy board which I tool around LaJolla Shores, the caves, Mission Bay, San Diego Bay, etc but I have not rigged it for fishing. Last week I fished the Green River in Utah for the first time. There was a mother/daughter on SUP’s cruising down the river, even through the rapids, which looked like a blast. I spoke to them a little and they are required by regulation on that river to use inflatable SUP’s.
They say that is to avoid damage to the board by hitting rocks, etc. Makes sense.
For a broad range of fishing, ocean, lake, bay and river an Inflatable may make sense. Especially with tight storage requirements, you can just deflate with a pump, roll it up and store it. They appear very solid.
