I can provide some insight on a Gheenoe LT25. I just bought one a few months ago and have fished it pretty hard since.
Pros:
- Can get ridiculously skinny. This can definitely help if you fish shallow water a lot.
- Light enough that if you get stuck, you can just get out and push it on out.
- Surprisingly stable. The LT25 has a wide beam which really helps with stability.
- Handled moderate to light chop quite well. I have had it out in 1-2 foot chop and it's done fine.
- Probably would handle river fishing pretty well. Maybe not as well as a jet but I imagine it would be a lot of fun.
- Would be perfect for the snakehead fishing that some of the VA kayakers have really been dialing in.
- Priced well. There are two in NC for sale right now that look great
Cons:
- Would be miserable with 3 people in the boat.
- I would not feel comfortable taking it out into deep water in the bay. I think it's fine on the flats and rivers you mentioned as well as the shore.
- Not a ton of storage.
