Boat Description

Introducing the 1984 Post 43 Sportfish, "UN DIA"—a classic vessel that perfectly marries timeless design with the renowned reliability and performance that Post Yachts are celebrated for. This sought-after sportfishing platform boasts a robust construction, sharp entry, and an efficient cruising speed, making it a favorite among serious anglers and cruisers. Equipped with twin Detroit Diesel 6-71T engines, "UN DIA" promises dependable performance, with both engines having undergone professional rebuilds—the port engine in 2020 (approximately 45 hours) and the starboard engine in 2024 (approximately 15 hours)—ensuring years of robust service ahead. The 6-71 series engines are celebrated for their durability, ease of maintenance, and global parts availability, making them a trusted choice among boaters. In June 2025, "UN DIA" received fresh bottom paint, prop tuning, Prop Speed application, and replacement of Cutlass Bearings on both props, along with various maintenance tasks to keep her in excellent condition. Though she has spent the last 16 years in saltwater, most of her life has been spent in freshwater, stored safely in a covered boathouse, contributing to her impressive overall condition. Her Gelcoat remains in significantly better shape than that of comparable vessels from her era. At the helm, you'll find a new Simrad multifunction display equipped with Radar, Plotter, and Depth Sounder, complemented by a standalone Simrad Autopilot for easy and precise navigation. These modern enhancements make "UN DIA" perfectly suited for both offshore fishing excursions and leisurely coastal cruises. The Post 43 features a practical and spacious layout, including a large cockpit, wide side decks, and a well-equipped salon with a galley and two staterooms—ideal for weekend getaways or extended adventures on the water. Whether you're chasing tuna offshore, cruising along the coast, or enjoying sunset outings with family and friends, "UN DIA" embodies the performance, heritage, and comfort that define the legacy of Post Yachts.
