What an AV/IT officer needs on paper (2026)
Owns the entertainment, networking and satellite systems that sit outside a traditional ETO's marine-electrical remit. On yachts under about 100 metres the same person often wears both hats; above that, yachts typically carry both a dedicated ETO and a dedicated AV/IT Officer. Plus the basics.

What catches engineering crew out?
The Y1 to Y4 yacht engineer route closed to new entrants on 31 December 2022, and new engineers now go through the Small Vessel structure in MSN 1904. Many yachts run an electrical specialist under the ETO job title without the formal certificate, which is allowed when no ETO is listed on the Safe Manning Document. High voltage training only bites when the vessel generates or distributes over 1000 volts, so it is a vessel fact rather than a rank requirement.
