This depends on the design of the boat to a certain extent, however typically when a yacht is heeling it would be moving quickly, causing the bow to raise and thus less surface area contacting the water. The majority of single hull sailing yachts would have less surface area contacting the water when heeling.
A sailboat will have positive buoyancy if the weight of the boat is less than the weight of the water it takes the place of. The weight of the water that is being occupied by the hull is displacement.
No a pwc is a waverunner or jet ski.

Sure - that's why it floats.

To determine the hull speed of a sailboat, multiply the square root of the length at the water line by 1.34. The answer will be in nautical miles per hour.
If the surface of the water is smooth, and you are on a beam reach or broad reach, you may get as much as 8 mph out of your small craft. CAUTION: If the wind is gusting, you risk a knockdown.

Water surface tension hold the needle on the water surface.
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
