I agree with the others that good quality inflatable kayaks are a good way to go. We have been using two Advanced Elements "Advanced Frame" kayaks for about 15 years and their performance is excellent. Their current price on Amazon is $499 each. They weigh 36 pounds and their downside is that cleaning and drying after a saltwater trip is time-consuming.
This year I bought two Advanced Element "FireFly" inflatable kayaks on Amazon for $200 each. The Amazon price is a moving target, with the current price being $229. They weigh only 16 pounds each and they are much easier to clean and dry. Their performance is not quite as good as the heavier ones, but it is very acceptable. I am 6-feet tall and 200 pounds, and I fit comfortably inside the kayak with my shoes off. With shoes on, I am more comfortable with my knees raised because the bow is very narrow inside.
Our 21-foot two-person kayak is out of the question for boat trips. It has far superior performance, but its 85 pounds of fiberglass makes it hopeless to load onto the boat.
