A designated person ashore (DPA) is the shore-based link between your yacht’s crew and its top management. Under the ISM Code, a commercial yacht on international voyages must have one. The DPA monitors safety and pollution prevention and gives the vessel direct support — so choosing the right person, and giving them real authority, matters from day one.
What the ISM Code Requires
The International Safety Management (ISM) Code applies to commercial yachts of 500 GT or more, and to yachts carrying more than 12 passengers on international voyages. If your yacht falls into either group, the Code sets out how safety and pollution prevention must be managed — both on board and ashore.
At the centre of that structure sits the DPA. The Code requires a shore-based person with direct access to the highest level of management. That access is not a courtesy. It means the DPA can raise a safety concern at the top of the company without going through layers of staff who might filter it out.
The DPA’s role covers three connected jobs:
- Monitoring safety and pollution prevention. The DPA keeps an eye on how the yacht’s Safety Management System (SMS) is actually working in practice, not just on paper.
- Providing vessel support. Crew need a shore contact who can help with safety questions, drills, reporting and follow-up.
- Linking ship and shore. The DPA makes sure safety information flows both ways between the yacht and management.
One important limit: the ISM Code does not apply to pleasure yachts. This article is about commercially operated yachts, where the Code and the DPA requirement do apply.
Why the DPA Matters to the Owner
It is tempting to treat the DPA as a name on a form. That is one of the most common mistakes, and it has practical consequences.
Without a properly qualified DPA, the safety management structure has a gap. Crew may have no clear route to report a problem. Small issues stay small only if someone ashore is tracking them. A DPA who understands the yacht’s operations can spot patterns — repeated equipment faults, near-misses, training gaps — and act before they become incidents.
The DPA also matters commercially. The yacht’s Document of Compliance (DOC) and Safety Management Certificate (SMC) depend on a working SMS and a credible shore-side structure. If a flag administration or inspector finds that the DPA role is nominal, that raises questions about the whole system.
In short: the DPA is an operational safety role, not an administrative formality. Owners who treat it that way get more value from it — and fewer problems at inspection time.
What Makes a Good DPA
The Code expects the DPA to genuinely understand three things:
- The ISM Code itself — what it requires and how it is applied in practice.
- The yacht’s operations — how the vessel is run, its routes, its crew structure and its risks.
- Emergency response — what happens when something goes wrong, and how shore support fits in.
A DPA does not need to be a lawyer or a surveyor. They do need enough technical and operational knowledge to ask sensible questions, challenge weak answers, and know when to escalate.
They also need real authority. If the DPA cannot pick up the phone to top management, the role does not function as the Code intends. When you appoint someone, make that access explicit — in the SMS and in practice.
How the Structure Is Set Up
Setting up the DPA role is part of a wider process. The usual sequence is:
- Build the Safety Management System. The SMS sets out procedures, responsibilities and reporting lines for the yacht and the shore organisation.
- Appoint a qualified DPA. Name the person, define their duties, and confirm their direct access to top management.
- Obtain the Document of Compliance (DOC). This is issued by the flag state to the company, confirming the shore-side SMS meets the Code.
- Obtain the Safety Management Certificate (SMC). This is issued per vessel, confirming the yacht operates in line with the approved SMS.
The DOC comes first because it covers the company and its shore organisation, including the DPA. The SMC then follows for each individual yacht.
Timelines vary. The DOC and SMC process typically takes three to six months, depending on the flag administration and how ready the SMS is. A well-prepared system moves faster; a thin one tends to stall.
Common Mistakes to Avoid
Most problems with the DPA role come down to a handful of recurring errors:
- Appointing an unqualified DPA. Someone with no real understanding of the ISM Code, the yacht or emergency response cannot do the job properly.
- Weak SMS documentation. If procedures are vague or out of date, the DPA has nothing solid to work with.
- Unclear reporting lines. Crew need to know who to contact and how. The DPA needs to know who to escalate to.
- Treating the DPA as a formality. A name on a certificate, with no involvement in operations, defeats the purpose of the role.
Each of these is fixable, but it is far easier to get the structure right at the start than to rebuild it after an inspection finding.

What This Means for Different Yachts
Not every yacht faces the same requirements. The ISM Code applies to commercial yachts of 500 GT or more, and to yachts carrying more than 12 passengers on international voyages. If your yacht is commercially operated and falls into either category, the DPA requirement applies to you.
Pleasure yachts are outside the ISM Code, so the DPA requirement does not apply to them. If you are unsure which category your yacht falls into, that is worth clarifying early — it shapes everything that follows.
For yachts that do fall under the Code, the practical question is not whether to have a DPA, but who that person should be and how their role fits your operation.
What the Owner Should Do Next
Start by confirming your yacht’s position: is it commercially operated, and does it meet the size or passenger thresholds that bring it under the ISM Code? That answer determines whether a DPA is required at all.
If it is, work through the practical steps:
- Decide who will act as DPA, and check they have the ISM, operational and emergency-response knowledge the role demands.
- Make their direct access to top management explicit in the SMS.
- Review your SMS documentation before you apply, so the DOC and SMC process is not held up by gaps.
- Set clear reporting lines between crew, the DPA and management.
Flag-specific requirements vary, so it is worth checking what your flag administration expects before you finalise the structure. Getting this right early saves time later.
Where BlueWater Registration Services Can Help
BlueWater Registration Services can assist with flag-specific ISM guidance and a DPA structure assessment — helping you confirm what applies to your yacht and how the shore-side role should be set up.
For owners registering a yacht under the UK Part 1 register, BlueWater also arranges registration packages. For private use, boats from 1 m are covered from €1,350 excl. VAT, which includes UK Limited Company Incorporation, the Official UK Part 1 Certificate of Registry, the Official Certificate of Incorporation, and registered office service for the first year. For commercial use, boats from 1 m are covered from €1,950 excl. VAT, which includes the same items plus a Safe Manning Certificate.
These packages cover boats from 1 m in private or commercial use. A boat length or use outside those lines is not something BlueWater arranges, so this option would not apply.
Conclusion
The designated person ashore is the shore-based safety link that the ISM Code requires for commercial yachts of 500 GT or more, and for yachts carrying more than 12 passengers on international voyages. Done properly, the role gives crew a direct route to management, keeps the SMS working in practice, and supports the DOC and SMC process. Done as a formality, it leaves a gap that inspections tend to find.
Your next step is to confirm whether the ISM Code applies to your yacht, then decide who your DPA will be and how their authority will work in practice. BlueWater Registration Services can assist with further guidance on flag-specific ISM requirements and DPA structure.
