I own a Cape dory 22..virtually the same boat. Had it three years now.
Know of one trans-Atlantic sail. I have taken several modern design sailors
for a sail... let 'em sail it. They ALL loved the boat. It does not sail as close to wind as modern fins. This is am much over rated asset. It has a narrow beam and is initially tender but stiffens up past 20 degrees.
Off the wind is is a beauty... Suggest you read about "form" stability vs. Ballast stability.
The Cape Dory 22D had an inboard diesel.
