This 1999 Tiara 3500 Open is an exceptionally well-maintained diesel-powered express cruiser with an extensive history of cruising the Bahamas and Florida Keys. Owned by just three owners, this Tiara has been thoughtfully upgraded, consistently serviced, and equipped for extended cruising and self-sufficient travel.

Powered by twin Cummins 6BTA diesel engines with approximately 1,420 hours and a Westerbeke 5kW generator with approximately 550 hours, this Tiara offers the reliability and capability that have made the 3500 Open a highly regarded cruising and fishing platform. The vessel remains in regular use, so engine and generator hours may increase slightly.

Both the current and previous owners have followed Seaboard Marine maintenance practices, with service performed at regular intervals and maintenance records available for review.

Unlike many boats of this vintage, this Tiara has been extensively equipped for remote cruising. From upgraded Raymarine navigation electronics and carefully selected ground tackle to onboard spare parts and enhanced engine room systems, considerable attention has been given to making this vessel practical and dependable for extended trips.

Recent 2026 improvements include new bottom paint, PropSpeed on underwater metal components, a replacement Bimini top, updated exterior upholstery, and complete annual service on both Cummins engines and the generator.

With its proven cruising history, extensive maintenance, and thoughtful upgrades, this Tiara 3500 Open represents an excellent opportunity for buyers looking for a well-equipped diesel express cruiser.
