Hull cleaning and paint work

• No business may clean hulls in the water without a Port In-Water Hull Cleaning Permit (District Code §4.14, Ordinance 3025, 2021).
• Marinas, mooring companies and yacht clubs must see proof of a valid permit before any in-water hull cleaning, keep copies for 90 days after the permit expires, and notify the Port within one business day if they find unpermitted cleaning.
• Cleaning must follow industry best management practices (BMPs), and cleaning that leaves a visible paint plume or cloud is prohibited.
• Each permitted business files a BMP Plan Verification & Training Form listing the divers it has trained.
• Zinc anode changes and underwater work on shafts, running gear and through-hulls are not “in-water hull cleaning” under the ordinance.

For boat owners

Slip fees

The Port does not set slip rates; each marina does. Example: Kona Kai Marina publishes month-to-month permanent slips from $32/ft (30 ft) to $70/ft (100 ft), with no effective date, and lists liveaboard at $600/month.

Copper paint and hull cleaning

If you hire someone to clean your hull in San Diego Bay, they need the Port's In-Water Hull Cleaning Permit, and your marina is required to check it. The Port encourages boaters to consider converting to alternative (non-copper) hull paints.
