What is the primary function of the lifting strakes on the vessel?

Increase weight

Enhance speed

Improve sea keeping and stability

The primary function of the lifting strakes on a vessel is to improve sea keeping and stability. Lifting strakes are designed to create lift as the vessel moves through the water. This lift helps to raise the hull out of the water, which reduces drag and allows the vessel to navigate more smoothly over waves. By enhancing the vessel's stability, especially in rough conditions, lifting strakes contribute to a safer and more comfortable ride for both the crew and passengers.

In addition to their primary function, while lifting strakes may have some influence on speed and potentially aid in fuel efficiency due to reduced drag, their main purpose is to support stable and efficient handling of the vessel. Thus, the choice identifying their role in enhancing sea keeping and stability directly addresses the core benefits of incorporating lifting strakes into a vessel's design.
