Description
Serenity Afloat represents a rare opportunity in today's market — a classic Bayliner 4788 Pilothouse with the timeless, elegant lines that turn heads on the water. With her raised pilothouse profile, generous proportions, and unmistakable presence, she's a boat that looks as good underway as she does at the dock.
Powered by twin Cummins 6BTA-5.9 370 hp diesels, she's built for serious cruising — a proven Great Loop boat, an exceptional liveaboard, and ideally suited to long-distance passages. Three private staterooms sleep six, with a bright, spacious salon and full galley designed for extended time aboard.
The boat shows that the current owner has pride of ownership and has invested thoughtfully and continuously: NEW Bimini (2024), NEW hydraulic dinghy lift (2024), Victron lithium house bank with smart monitoring, all-LED interior conversion, fresh flooring and refinished wood throughout (2018), cream Ultra Leather salon upholstery (2020), updated galley with extra-large sink (2025), replaced aluminum waste tank (2019), and a new memory foam master mattress (2024). Many more updates are detailed in the full spec list below.
