Broker's Comments

Aggressively priced! This beautiful well-equipped new Mariner 42 Classic Trawler is offered at a very great reduction from its retail price.

This new 2010 Mariner 42 Classic trawler is in-stock at Waterline Boats. Fully equipped with Raymarine navigational electronics, a top-quality inverter, Northern Lights 5kw generator, cabin heat and a windlass and ground tackle, she's ready-to-cruise -- most buyers will only want to add their choice of a dinghy and davit system.

This boat features a unique and valuable upgrade in its Cummins QSL-series commercial-duty engine. It achieves higher torque, longer life, and better fuel economy than recreational-duty diesel engines of comparable horsepower. The result is a boat that powers through waves without strain, extends cruising range, and saves dollars on diesel fuel!

This boat uses a proven hull design -- thousands of vessels have demonstrated their safety and seaworthiness using this hull. Designed in the classic Grand Banks Europa style, she has wide covered side decks, all-around visibility from the lower helm, high bulwarks, plenty of interior light, and a large cockpit. This boat is a safe passagemaker with accommodations to comfortably sleep up to seven.
