Scattering Ashes at Sea: Rules, Costs, and How to Plan an Ocean Ceremony

Ocean scattering is the most regulated form of ash scattering in the United States, but the rules are straightforward once you know them. The EPA governs the process under the Marine Protection, Research, and Sanctuaries Act, and the core requirement is distance: cremated remains must be released at least three nautical miles (about 3.45 land miles) from shore.

No advance permit is needed. You do need to file a short report after the ceremony. Here is the full process from start to finish.

EPA Rules for Ocean Scattering

Three requirements apply to every ocean scattering in U.S. waters:

Distance. Three nautical miles minimum from the nearest shoreline. Scattering directly from beaches, piers, or jetties is not legal under federal regulations. A boat is the most common way to reach the required distance; an aircraft can also be used if the release meets the distance and applicable aviation rules.

Materials. Only 100% biodegradable materials may enter the water. Flowers with stems and leaves — fine. Biodegradable urns designed to dissolve — fine. Metal urns, plastic containers, synthetic ribbons, floral foam, or balloon releases — prohibited.

Reporting. Within 30 days of the ceremony, file a Burial at Sea Report through the EPA's Ocean Dumping Management System. The form asks for the legal name of the deceased, date of the event, GPS coordinates of the scattering location, and the vessel name. It takes about 10 minutes to complete online.

One detail that catches people off guard: pet remains cannot be commingled with human remains under the MPRSA general permit. If you want to scatter both, they need to go into the water separately.

Charter Boat Options and Costs

Most families use a licensed charter service. Costs vary by region and format:

• Private attended charter: $500–$2,500. You and your guests board the vessel, the captain navigates to a compliant distance, and the family performs the ceremony. Typical duration is 1–3 hours. Passenger capacity ranges from 6 to over 100 depending on the vessel.
• Unaccompanied scattering: $200–$500. You ship or deliver the cremated remains to the charter service. The captain scatters the ashes at sea on your behalf, typically providing GPS coordinates and sometimes photos or a video. Non-refundable once the remains are in the captain's custody.
• Fuel surcharges and extended charters can add $100–$500 depending on the port and how far offshore you want to go.

When comparing charter services, confirm: the captain holds a valid U.S. Coast Guard license, the vessel has adequate passenger insurance, the weather cancellation policy includes rescheduling at no additional charge, and they handle the EPA filing (many do, but not all).

Planning the Day

Weather. A calm day with light winds matters more than you might expect. Wind above 15 mph can carry ashes back toward the boat and passengers. Charter captains monitor conditions and will reschedule if conditions are unsafe — ask about their threshold when booking.

Wind direction. The captain will position the vessel so the wind carries remains away from the boat. If you are scattering yourself rather than using a scattering tube, stand at the stern (back) of the boat, downwind, and release the ashes low near the waterline.

What to bring. Biodegradable flowers (no rubber bands or plastic wrapping), the remains in their transport container, the ceremony script or readings you have prepared, and a water-soluble urn if you plan to release the ashes in a container rather than loose.

What not to bring. Synthetic flower arrangements, balloons, metallic decorations, non-biodegradable glitter, or glass containers.

Water-Soluble Urns

Biodegradable urns designed for water scattering dissolve within minutes to hours after entering the ocean. Materials include recycled paper, sand, Himalayan salt, and plant-based gelatin. Prices range from $30 for a basic paper urn to $300+ for a hand-painted or custom-shaped vessel.

The urn should be placed gently on the water's surface, not thrown. Most designs float briefly — anywhere from 30 seconds to several minutes — before taking on water and sinking. This floating moment is often the emotional center of the ceremony.

Scattering in Other Waterways

Rivers, lakes, and inland waterways have different rules than the ocean:

• California prohibits scattering in freshwater streams and lakes. State law sets a 500-yard minimum from the ocean shoreline, while the EPA's three-nautical-mile minimum applies to ocean scattering in U.S. waters.
• In the UK, no license is needed for tidal coastal waters, but the Environment Agency recommends scattering at least 1 kilometer upstream from any drinking water intake.
• In Canada, scattering is permitted on public waterways including the Great Lakes without a permit, though Parks Canada prohibits scattering in water bodies within national parks.
• In Australia, beach and ocean scattering are generally permitted without a formal permit as long as the ceremony remains private and non-commercial.

State and local rules vary significantly. Some states have no restrictions on inland water scattering; others require you to contact the local water authority. When in doubt, check with the governing agency for the specific body of water.

After the Ceremony

File the EPA report within 30 days. Record the GPS coordinates — many charter services provide these automatically. Some families register the location with The Ashes Register, a private service that creates a permanent, shareable record of the scattering site for future family members.

If you are organizing a sea scattering and need help with the logistics — the EPA filing, charter comparison, ceremony planning, and the documents you will need — the Scattering Ashes toolkit includes a vendor comparison worksheet, ceremony planning script, and step-by-step administrative tracker covering the full process from receiving remains to the final filing.
