1999 Mainship 350 Trawler – Seaglass

The 1999 Mainship 350 Trawler “Seaglass” is a highly sought-after single-diesel cruising trawler offering efficiency, comfort, and easy handling. Powered by a dependable 300hp Caterpillar 3116, she delivers economical cruising performance, paired with a Kohler 8kW generator (1,215 hrs) for extended stays aboard.

The guest cabin with twin berths and a separate enclosed shower make her ideal for cruising couples or small families.

Her flybridge is fully protected with a Stamoid Bimini and full Strataglass enclosure, and docking is simplified with a Side-Power bow thruster. Updated electronics include a Raymarine Axiom RV9 touchscreen MFD with Quantum radar, VHF with RAM mic, and full upper and lower helm stations.
