Can our port captain be the Cybersecurity Officer? The four paths, compared honestly

Yes. The rule permits your port captain — or your safety manager, your office manager, your owner, or an outside firm — to hold the Cybersecurity Officer designation. §101.625 allows the CySO to have other duties, to cover multiple vessels and facilities provided each is listed in the plan, and to be a third party. The qualification standard is general knowledge through training, education or equivalent job experience — no certificate, no IT degree. Almost anyone conscientious can lawfully be named.

Which is exactly why "can they" is the wrong question. The rule leaves the designation decision to you, and by Jul 16, 2027 you have to have made it, in writing (§101.655). What follows is the decision table we actually use on readiness calls: the four realistic paths, what each is good for, and what each one costs that its advocates tend to leave out.

The four paths

The port captain path, walked through

This is the path most ten-boat companies reach for first, and it is a good one when it is real. The case for it: the rule's fifteen duties are overwhelmingly ensure duties — an accountability role, not a hands-on-keyboard role — and a port captain already runs an accountability calendar under Subchapter M. The knowledge bar was written to be clearable: of the twelve required knowledge areas, a working port captain starts with roughly a third in hand and another third familiar in shape, with true gaps only in the cyber-specific areas — we lay that arithmetic out in the twelve things a CySO must know.

The case against it, stated as plainly: the designation adds a permanent on-call duty to a job that is already full. The Coast Guard must be able to reach the CySO at any hour. Known exploited vulnerabilities must be mitigated without delay, which means somebody watches a federal catalog every week. And when the person leaves — port captains do — a 96-hour clock starts to notify the Coast Guard and amend the plan (§101.630(e)). The port-captain path works when the company buys the support structure with the title: a real course, a named and trained alternate, and a standing partner behind the after-hours duties. It fails when the title is the whole investment.

The office manager path

At many small companies the office manager already administers Microsoft 365, pays the invoices, and talks to the IT vendor — so the cyber half of the job is closer to their desk than to the wheelhouse. The catch is the first knowledge area on the rule's list: general vessel and facility operations. A CySO who has never ridden a crew change will struggle to call which systems are critical, to run a drill that feels real to a wheelman, or to brief the fleet when conditions change. The fix is structural, not personal: name a wheelhouse deputy, and put the vessel-side duties in both job descriptions.

The fractional path

The rule permits an outside CySO of record, and for some companies it is the honest answer rather than the convenient one — no internal candidate, or a preference for having the liability and the technical watch held professionally. We have written up what the arrangement actually involves, month by month, in what does a fractional Cybersecurity Officer actually do, including the questions to put to any provider, us included. The short version: demand the designation in writing with a 24/7 chain and a named alternate, every vessel listed, your records in your possession, and an auditor who is not the same firm.

The owner path

For a two- or three-boat company where the owner already is the safety department, the rule allows the owner to self-designate. It works, and we have seen it work. Go in clear-eyed: the owner takes on the same reachability duty, the same calendar, and the same accountability — personally. Owners who were hoping the rule could be delegated away should notice that this path runs the opposite direction.

Whichever path: the designation letter

The designation lives in Section 1 of the Cybersecurity Plan, and the owner's duty to make it is part of §101.620. Written down, it needs at minimum:

• The CySO's name and title
• The alternate's name and title — not required by the rule, always recommended by us
• 24/7 contact information for both
• The list of every vessel and facility the CySO covers, if one person serves several
• A statement of the CySO's authority to carry the duties, including delegating tasks while retaining responsibility
• The owner's signature and date

Keep it current. A change of CySO starts the 96-hour notice-and-amend clock (§101.630(e)) — the fastest clock in the whole rule, and the reason the alternate line matters more than it looks.

The cost no path avoids

One number belongs in every version of this decision: the annual independent audit. §101.630(f) requires the plan audited every year by someone independent of the measures being audited, so the CySO — any CySO — cannot audit their own program. A company that designates internally to keep the money inside still buys an outside audit every year, forever. The audit and records obligations are explained at /the-rule/records-and-audits.

We have condensed all of this to two printable pages — the four-path decision table, the designation-letter checklist, and the twelve knowledge areas as a tick-box self-assessment. It is called Choosing your Cybersecurity Officer, and it is free in the downloads, alongside the rest of the rule explained at /the-rule/cybersecurity-officer.
