Does Your Marina Require Proof of Insurance for Divers? San Diego Marina Rules

Most marinas in San Diego Bay require any diver working on boats in their slips to carry current liability insurance, usually $1 million to $2 million in coverage, and to provide a certificate of insurance (COI) naming the marina as additionally insured. Some also want proof of the diver's San Diego In-Water Hull Cleaning Permit before they will let anyone in the water. If your diver cannot produce both documents, the marina can (and sometimes will) turn them away at the gate.

I have run into this at almost every marina I work in, from Shelter Island to Chula Vista. The rules are not identical from one dock to the next, but the intent is the same: the marina wants to know that if something goes wrong, there is insurance behind it, not just a guy with a wetsuit and a hose.

Key takeaways

• $1M to $2M in general liability coverage is the typical minimum marinas ask for
• Many marinas want a certificate of insurance (COI) on file, not just a verbal assurance
• Shelter Island Marina, Sun Harbor, and several Harbor Island docks have asked us for paperwork before allowing dive work
• Divers also need the San Diego In-Water Hull Cleaning Permit, which is separate from insurance
• If your diver cannot show both, you could be the one who gets a call from the harbormaster

Why do marinas care about diver insurance in the first place?

A diver working under a hull is doing something that can go wrong. Gear can snag a through-hull fitting, a prop can spin unexpectedly if someone bumps the key, or a diver can scratch bottom paint on a neighboring boat while maneuvering between pilings. Marinas have seen enough of this over the years that most of them now protect themselves by requiring vendor insurance before anyone gets wet.

It is not personal and it is not about doubting any particular diver's skill. It is standard risk management, the same reason a marina wants a fuel dock attendant or a bottom paint contractor to carry coverage too.

What San Diego marinas typically ask for

I have worked docks all over the bay and the paperwork requests follow a pattern, even though the exact numbers vary slightly by marina:

General liability insurance. Most want to see $1 million per occurrence, some ask for $2 million aggregate. This covers things like accidental damage to a hull, a dock, or another vessel.

Certificate of insurance (COI). This is a one-page document from the insurance company that lists coverage limits and often names the marina as an additional insured. Marinas keep these on file and may ask for a renewal every year.

Diver certification and hull cleaning permit. Insurance alone is not enough. San Diego requires divers doing in-water hull cleaning to hold a permit through the county, tied to environmental rules about paint particulates and copper discharge. A marina that is paying attention will ask for this too.

Some marinas are looser about enforcement than others. Shelter Island and Harbor Island tend to be more strict, partly because of the copper TMDL zone rules already in place there. Smaller docks in Mission Bay or Chula Vista sometimes do not ask at all, until an incident makes them start.

What happens if your diver is not insured or not permitted

If a marina finds out a diver working in their slips does not have insurance on file, a few things can happen. They may issue a warning and give the boat owner a deadline to switch vendors. They may bar the diver from the property entirely. In rarer cases, if damage happens and there is no insurance behind the diver, the marina or the boat owner can be left holding the bill.

I have seen boat owners get an unpleasant surprise this way, usually because they hired someone cheap off a flyer on the dock without asking a single question about credentials. It is worth 5 minutes to check before you hire anyone.

What to ask before you hire a diver

Ask for the COI directly. Any legitimate diver can produce this same day, either by email or from paperwork they carry. Ask about coverage limits specifically ($1M is common, $2M is safer). Ask if they hold the San Diego In-Water Hull Cleaning Permit, since this is separate from insurance and just as often required. If a diver hesitates or gets vague about any of this, that tells you something.

We carry liability insurance and hold our permit, and we send the COI to any marina office that asks, usually within the same day. It has never held up a job.

FAQ

Do all San Diego marinas require diver insurance? Not all of them enforce it strictly, but most marinas in San Diego Bay either require it outright or reserve the right to ask for it. Shelter Island and Harbor Island tend to be the most consistent about checking.

How much liability insurance should a hull cleaning diver carry? Most marinas ask for $1 million to $2 million in general liability coverage. This is standard in the industry and any diver doing this professionally should already carry it.

Is insurance the same thing as the San Diego hull cleaning permit? No. Insurance covers liability for damage or accidents. The permit is a separate county requirement tied to environmental rules about hull cleaning discharge. Divers need both to work legally and to satisfy most marina policies.
