Does the shape of an object affect flotation if the object is first submerged?

No. Buoyancy depends only on total volume of water displaced and the mass of the object, not the shape of the displacement. However, if the change in the shape affects the volume of water displaced, then the bouyancy of the object is affected. Scuba divers with wet suits know that the volume of their wet suit compresses as their depth increases, causing the suit (and the diver) to become less bouyant.
