Vessel Overview

This 56 Neptunus Flybridge has only had three owners since new. She was custom built and I just wanted to point out what makes this boat stand out versus other boats previously and currently on the market.

  • It was built in Canada with proven construction technology and craftsmanship.
  • It has the finest solid cherry woodworking and cabinetry on the market.
  • It is powered by proven Caterpillar 3406E engines providing the best performance for this hull and maintains the reputation of being trouble free. It is not under powered or over powered.
  • It was built with every option Neptunus offered including, two freezers, Fisher Paykel dishwasher, washer & dryer, Bose Stereo systems, upgraded bow thruster, hydraulic swim platform, hardtop with full bridge enclosure, Inverter, Head Hunter Heads etc.
  • It has never had any hull damage.
  • Maintenance has been performed as required.
  • It stands sea worthy for departure without notice.
  • With a "no shoe" policy, the interior is like new condition without any wear or tear.
  • It is maintained with open check book.

The most important feature that we enjoy most is the full beam sun deck directly in front of the fly bridge helm. No other vessel has this option and it absolutely the best seating area one can imagine.
