Broker's Comments

Owners want out of boating and have deeply discounted their 42’ Avanti Express 4085 for immediate sale ! This Avanti Express 4085 combines style and comfort as well as the melding of form and function. Boarding this stylish express cruiser you will find incredible space above deck-cockpit deck and swim platform as well as below deck. This fresh water, low hour, less than 510, express cruiser has accommodations for a family or two couples but room to entertain 6 – 8 adults with style and comfort . Well powered with twin 330 HP Cummins diesels, generator, electronics and creature comforts to make for cruising in style. Here is a “don’t miss this one opportunity” if you are looking for a larger express cruiser over 40’ but priced well under $100,000 give me a call to discuss the detail further with you.

This is a used boat and should be viewed as such. These boat details are subject to contract.
Note: Offers on the asking price may be considered.
