Broker's Summary

Bow Down is a beautifully maintained example of Bayliner's classic 4550 Pilothouse Motor Yacht - the same hull later marketed as the 4588 Pilothouse, one of the most successful Northwest-designed cruisers ever built.

This vessel combines Bayliner's efficient Ed Monk Jr. design with extensive interior and systems upgrades. She's powered by twin Hino EH700T 220-hp diesel engines, well-regarded for their reliability and efficiency. With her refined interior, upgraded systems, and solid mechanical condition, Bow Down is an excellent choice for extended Delta or coastal cruising.

The current owner has maintained the vessel with attention to detail, ensuring that mechanical, electrical, and interior systems are in good operating condition.
