The invention relates to a double-body wave breaking yacht, and belongs to the technical field of ships and oceans. The double-body wave breaking yacht comprises two double body side stems, a bottom deck, a main deck, a fly bridge deck, a platform and a middle fore body. The lower structures of the double body side stems are immersed in water, the middle fore body with the structure above the water surface is arranged right between the two double body side stems, and the middle fore body and a yacht body are connected into a whole. The end portions of the two double body side stems and the middle fore body are in a mutually-aligning trident structure. According to the yacht, the double body side stems and the middle fore body are adopted, so that the resistance exerted on the yacht body is reduced; and the excellent wave resisting performance is achieved, and the high navigational speed under the complex sea condition can be kept.
