Why bulb of bar or HP holland profile is pointed towards center ship?

The bulb of a bar or HP (high performance) Holland profile is pointed towards the centre of the ship for several reasons:

1. Reduced Resistance: By pointing the bulb towards the centre, the bulb creates a streamlined shape that reduces the resistance of the ship as it moves through water. The pointed shape creates a smoother flow of water around the bulb, minimising drag and increasing fuel efficiency.

2. Improved Manoeuvrability: The bulb's pointed shape towards the centre improves the ship's manoeuvrability by creating a favourable flow of water around the hull. This allows for better control and responsiveness, especially when making turns or changing course.

3. Enhanced Stability: The pointed bulb contributes to the overall stability of the ship by reducing the roll motion caused by waves. The bulb acts as a stabilising force, helping to keep the ship steady and reducing the risk of capsizing.

4. Reduced Noise and Vibration: The pointed shape of the bulb towards the centre helps reduce noise and vibration generated by the ship's movement through water. This can improve the overall comfort and habitability for passengers and crew on board.

5. Optimisation of Wave-making Resistance: The pointed bulb helps to optimise the wave-making resistance of the ship. It minimises the generation of waves, which reduces energy loss and improves the overall efficiency of the vessel.

By pointing the bulb towards the centre of the ship, designers and engineers can achieve a combination of reduced resistance, improved manoeuvrability, enhanced stability, reduced noise and vibration, and optimised wave-making resistance.
