The last steps of removing our inboard diesel engine were removing the propeller and filling the aperture. Both created a substantial drag; filling the area has enhanced Dawn Treader’s ability to sail in light winds. We are quicker to accelerate, and consistently achieve faster speeds. We are amazed with how our sailing performance has improved, and it makes voyaging without an inboard diesel easier!
