What should the operator of a powerboat a do if a powerboat be begins to cross the star board right side?

If a powerboat begins to cross the starboard (right) side, the operator should maintain a safe speed and be prepared to take evasive action if necessary. The operator should also keep a lookout for any other vessels and ensure they are following the proper navigation rules, particularly the "rules of the road." If it is safe to do so, the operator may consider altering their course to avoid a potential collision. Always prioritize safety and communication with other vessels when navigating.
