Displacement yacht gives you the comfort onboard and autonomy.
When your boat is displacement, that means that you can stay at sea for an extended time. Displacement hull is an obvious choice if you want to cover distances without the need to refuel. More often than not, displacement yacht will have a round bilge with one or even two pairs of anti-roll stabilizers. Submerged in the water displacement hull will travel with moderate speed.
Explorer yachts, trawlers and megayachts usually have displacement hull form.
Yachts with Fast Displacement hull is probably the best of both worlds.
Usually, Fast Displacement provides the comfort of Displacement yacht with speeds of a Planing Hull. The boat stays submerged in the water with a less rolling motion. This hull form allows you to burn less fuel at economical speeds and go fast when you need to make a swift passage. Azimut, Benetti, Heesen, Mangusta and some other builders have Fast Displacement yachts in their portfolio. Azimut, Benetti rely on the Displacement To Planing hull developed by Ing Pierluigi Ausonio, Heesen uses Fast Displacement Hull Form brought by Van Oosanen naval engineer.
