Find it before the surveyor does
Drawing review and gap analysis against class rules, the REG Yacht Code, SOLAS and the IEC 60092 series; preparation for class and flag surveys; and the documentation that has to be right before delivery.

Frameworks
And other IACS class societies: rules for electrical installations, HV systems and machinery.
Large yacht code requirements as applied by the Red Ensign Group flags.

The series governing electrical installations in ships: cables, switchgear, protection, HV.
UK MCA and other flag administrations: survey scope, documentation and certification.
A former member of BSI JPEL/18
JPEL/18 is the British Standards committee, run jointly with the IET, that contributes to the IEC standards for electrical installations in ships, the IEC 60092 series that class rules lean on. Having sat on it means reading a rule for what it is trying to achieve, not just what it says, and knowing where the margins are when a yard and a surveyor disagree.
