Sadly boats have gotten exponentially larger over the last 30 years. You might give BVI yacht charters a call and see about their 3 cabin Lagoon 380. If you have a solid resume on powerboats they might consider renting it to you if you promise not to sail!
We do the same as TIMRIM. My husband and I have sailed monohulls in the 37-44 foot range when it's just the 2 of us. We have never had a problem. I man the wheel and he does all the heavy lifting and sail adjustments. We have become quite proficient at picking up a mooring ball too. I think it works great when he hooks the ball and I steer.
