Supreme luxury with the steadfast dependability of Caterpillar propulsion, this Avanti has been well-cared for and used just enough to keep her in perfect running order (1750 hours), while preserving her impressive interior condition. 

A Hard to Find Cruiser!

Very few of these Avanti's were produced. The 4085 Avanti was a good example of Bayliner’s market prowess—a lot of boat for the money. Built on a solid fiberglass modified-V hull with a relatively wide beam, her midcabin floorplan is arranged with double berths in both staterooms and a convertible U-shaped lounge and full galley in the salon.

Note that each stateroom has a privacy door (rather than curtains), and the head is fitted with a separate stall shower. The amidships lounge/stateroom has a small sofa and partial standing headroom at the entrance. On deck, there’s a doublewide seat at the helm followed by a large circular settee aft (with a removable table) and a full wet bar to port. The Avanti’s deep swim platform can store a personal watercraft.

This rare cruiser is even more rare in that she is propelled by a pair of the venerable 375hp Caterpillar 3208's. Additional features include a gas-assist engineroom hatch, side-dumping exhausts and a reverse arch.
