I find kayaks the perfect dingy solution to keep things simple. We have two 9.5 foot recreational sit inside kayaks that live on a Yakima rack that attaches to the cabin top rails of our 25. They each weigh about 40 pounds. We keep a bow line attached to them and I can easily pull them forward while standing on the bow and while holding the bow line slide them off the bow rail and walk them to the stern. We board them off the swim platform while holding on to the cockpit side rail to step in and transfer to the sitting position.
Because we can launch and reload them in less then 10 minutes we use them much more often then anyone we have boated with that use
dinghies. We use them almost every day after we anchor for the night. I kayak fish almost everywhere we go and we like to explore shorelines and small creeks. We have seen some amazing wildlife and explored places that only a kayak can reach.
We also use them like others use conventional dinghies. When we cruised coastal Maine we found that due to the tides and rocky shoreline most of the towns and marinas had mooring areas and dingy docks. We have paddled in to do laundry or buy groceries and anything else people use dinghies for. We don’t have a dog to take to shore but I think it would work fine for smaller dogs.
On your Tom Cat with the radar and air conditioner you could use a conventional kayak rack between your cabin top rails with “J” cradles to hold the kayaks.
