Trawlers 1999 Mainship 350

Off Market since May 8th 2019

To see full description of this boat from the seller click on the Seller Description tab above.

Whats Next is a well-appointed and impeccably maintained Mainship 350/390 that will make someone a perfect Great Loop boat or comfortable vessel to cruise the islands. She is built on a modified-V hull with a shallow, full length keel. With a 14 2 beam, her very spacious salon/main cabin sports a well-equipped galley and plenty of room to move around. And with wide side decks, gate from the swim platform, stairs to flybridge, and walk-around queen, she has easy access all around. Powered with a single Caterpillar 3116, she has plenty of power to comfortably cruise at 8 knots while only sipping about 3 gallons of fuel per hour.
