(2) a cylindrical neck section in profile view; and

(3) a lower conical section in profile view with a sloping side extending from the cylindrical neck section;

b. at least one extending fin with an upper fin surface sloping towards the bottom surface and secured to and extending from the hull, the at least one extending fin configured to provide hydrodynamic performance through linear and quadratic damping, and wherein the hull provides added mass with improved hydrodynamic performance through linear and quadratic damping to the hull, and wherein the floating driller does not require a retractable center column to control pitch, roll and heave, and

c. a plurality of sloping connected sides forming the lower conical section, each sloping connected side having at least one of: identical angles for each sloping side and different angles for each sloping side.

2. The floating driller of claim 1 , wherein the hull is a shape inscribed within a circle.

3. The floating driller of claim 1 , further comprising a dynamic positioning system with thrusters for providing positioning of the floating driller.

4. The floating driller of claim 1 , wherein the at least one extending fin comprises added mass resulting in additional fluid displacement that improves heave control of the floating driller.

5. The floating driller of claim 1 , comprising a sloping extension segment between the plurality of sloping connected sides.

6. The floating driller of claim 1 , wherein the at least one extending fin is a plurality of segmented extending fins aligned with each other and attached circumferentially around the hull.

7. The floating driller of claim 1 comprising a recess in the hull and wherein the recess is a moon pool.

8. The floating driller of claim 1 , wherein the polygonal shape of the hull comprises a plurality of flat planar metal plates forming a curvature of the hull.

9. The floating driller of claim 1 , wherein the extending fins are tanks.

10. The floating driller of claim 1 , further comprising an extending bottom edge extending from the extending fin decreasing hull motion.

11. A floating driller comprising:

a. a hull with a hull plan view that is circular or polygonal, wherein the hull comprises:
