1978 Mainship 34 Trawler - Perkins Diesel ? Economical ? Ready for Adventure

Classic lines, proven performance, and legendary reliability - this 1978 Mainship 34 delivers it all. Powered by a dependable Perkins diesel, she?s built for the boater who wants to cruise farther, burn less fuel, and spend more time enjoying the journey.

The Mainship 34's single-diesel, semi-displacement design has made her a Great Loop legend and a go-to choice for economical coastal cruising. She offers excellent range at 7-9 knots, while the Perkins engine is known for running strong for thousands of hours with minimal fuss.
