COLREGs (international rules to not have collisions at sea on account of everybody is agreed that would be bad)
A.2b. "In construing and complying with these rules due regard shall be had to all dangers of navigation and collision and to any special circumstances, including the limitations of the vessels involved, which may make a departure from these rules necessary to avoid immediate danger"
Basically, if obeying the other rules mean you'll get hit by an oil tanker, Rule 2b says ignore those other rules so that you don't get hit by an oil tanker. So yeah, Jack ought to order his engineers to go fix this.
In case anyone regularly has trouble not getting hit by an Oil Tanker, I'd like to recommend John W. Trimmer's excellent book: How to Avoid Huge Ships[1].
