2003 Mainship 430 Aft Cabin Trawler - "Sea Suite II"
Location: Punta Gorda, FL
"Sea Suite II" is hands down the finest, most meticulously upgraded Mainship 430 on the market today. The current owner has invested nearly $100,000 in improvements over the past year alone, backed by all records and receipts. Featuring twin 370hp Yanmar diesels with up-to-date major services, completely new canvas and enclosure, a modernized interior, and upgraded Garmin electronics, this yacht is fully sorted and ready to turn the key.
Whether you are preparing to tackle America's Great Loop or embarking on extended coastal cruising, this vessel delivers ultimate comfort, safety, and reliability.
Mechanical, Power & Electrical Systems:
Positioned on the exact same level as the salon, this expansive galley features a dedicated deck access door and beautiful Corian countertops.
Broker's Notes:
"I sell a ton of Mainships as a sponsor of the Great Loop Cruisers Association. I can say with absolute certainty that I have never seen a nicer, better-maintained, or more completely equipped 430 anywhere. The owner spared zero expense making this boat perfect. Do the Loop in absolute comfort and style. See this one today... you will want to make it yours immediately!"
