Yes having a hook or concave like that hull has will kill speed, due to sucking the hull to the water. You can also get the opposite in a hull that has a rocker in the hull, where the hull has a convexe or bulges out at the rear area of the hull bottom. That will cause the hull to porpoius back & forth. I also like to scuff the bottom of the hull with 400grit sandpaper back & forth direction, taking off the smooth polished surface of the hull. This reduces surface tension between the hull & water surface.
@@gillian9178 yes correct. It Can cause many issues to how the boat runs. The 400 grit sand is great trick to gain an increase to performance. I definitely do that trick and a graphite hydrophobic paint to the bottom as well. Trying to get anything I can from the hull reducing any surface tension and drag
