I recently purchased an inexpensive inflatable dinghy built by Bestway. It is very small, I believe 90 inches. It feels thick and durable. I inflate it to use and deflate it to store on my boat. It easily fits under the cockpit seating. It weighs 35 lbs and cost just a little over $300. So far I’ve used it 3 times and really like it. Google the brand and you will find a few different models.
