*Broker's note: There is a lot to love about this vessel, and one thing stands out to me: The owners. Many listings say, "meticulously maintained" but I assure you, this one IS. The owners religiously flush the engines and generator with fresh water, preventing buildup and corrosion, keeping them new, as one example of how they pamper her. If you are in the market for a Lagoon, please do not buy one without taking a look at Acting Casual. You will thank yourself. - Jennifer
