General Information

BigKanu is a Lateen rigged motor-sailor with rig suspended in an A frame for powerful sail boost power. She is designed to make long distance headway as a motor sailor with small fuel use. She is robust and stable due to her alloy build and low center of gravity. Beaching is possible even on rocky ground as its built tough underneath for this very purpose.

Using her own truck wheel trolleys she can be chain blocked up the beach for maintenance to avoid the cost of slipping a boat with a 12m beam.

MORE A & Q's:

As her owner I designed the boat and it was built by New, Zealand builders called Mithral Marine in Surabaya.

The Lateen motor/sailing mast is low, in height to reduce the overturning motion. The yacht has, a gross charter income of between $150, 000 to $200, 000 USD for all those interested in running a business while living the dream!?.
