The new INACE 135’ (41.2M) LONG RANGE MEGA MOTOR YACHT has the heart and soul of the proven INACE EXPLORER VESSELS. Essentially she is a world cruising ship dressed in Yacht Attire. She is designed to have a “yacht” feel with the efficiency and reliability of the aft house explorer vessels.
The 135' has a Kirschstein Design interior and exterior design. The high efficiency hull design was done by Overing Yacht Design, a recognized expert in this field. The vessel was tank tested in different sea states. In sea state 4 (8' 3" wave heights and wind speed of 27 knots) dead on the bow she has a 4000 plus nm range; at 10 knots she has a range of just under 6000 nm; in calm waters at 12 knots she has a range of 7000 nm, The hull was tested at over 15 knots. The 135 was not only created for efficiency but also to be seaworthy and sea kindly. Her moderate 7' draft allows her to enter harbors other vessels cannot while her outstanding use of space gives you the features of a much larger vessel.
The first in this series is under construction and has a upgraded interior done in paneled American cherry and custom moldings. The design incorporates large windows throughout the vessel creating stunning viewing areas and a light open feel to the interior.
A new construction takes approx 30 months.
