MARPOL Annex V for Superyachts
MARPOL Annex V governs the discharge of garbage from ships and applies to all vessels including superyachts. Superyachts of 100 GT and above, or certified to carry 15 or more persons, must carry a Garbage Management Plan and maintain a Garbage Record Book. Plastic discharge is prohibited in all ocean areas; food waste discharge is subject to strict distance and processing requirements.
Definition
MARPOL Annex V is the international regulation that prohibits plastic discharge and regulates garbage management for all vessels including superyachts, requiring a Garbage Management Plan and Garbage Record Book for vessels 100 GT and above.
What MARPOL Annex V Covers
MARPOL Annex V is the international regulation governing the discharge of garbage from ships into the sea. It entered into force in 1988 and was substantially strengthened by the 2011 amendments, which took effect on 1 January 2013. The revised Annex V introduced a near-total ban on garbage discharge at sea, with only a narrow set of exceptions for specific waste streams under strictly defined conditions. The regulation applies to all vessels, including private yachts, superyachts, and charter vessels of any size. For superyacht operators, compliance is not optional: MARPOL Annex V obligations apply from the moment a vessel enters any sea area, regardless of flag state. Annex V categorises garbage into the following waste streams: plastics (including synthetic ropes, fishing gear, and plastic bags); food waste; domestic waste (glass, metal, crockery, paper not segregated as plastics); cooking oil; incinerator ash; operational waste (dunnage, lining, packaging materials not contaminated); and e-waste (electrical and electronic equipment). For a yacht, food waste is the only one of these categories that may ever be discharged at sea, subject to distance from land, sea area, and processing method. The most important rule: the discharge of all plastics into the sea is prohibited absolutely, in all sea areas, at all times.
Superyacht-Specific Obligations: Garbage Management Plan and Record Book
Under MARPOL Annex V, superyachts of 100 gross tonnes and above, and vessels of any size certified to carry 15 or more persons, have two mandatory documentation obligations: a Garbage Management Plan (GMP) and a Garbage Record Book (GRB). The GRB threshold was lowered from 400 GT to 100 GT on 1 May 2024; for vessels below 100 GT certified to carry 15 or more persons, the GRB applies on voyages to ports of other MARPOL Parties. The Garbage Management Plan must be written, kept on board, and describe the procedures for collecting, storing, processing, and disposing of garbage. It must assign responsibilities to crew members and include procedures for informing guests and passengers of their obligations not to discharge prohibited items at sea. For charter yachts that carry guests who may not be familiar with maritime waste regulations, the plan must include a guest briefing component. The GMP is a living document — it must reflect the actual operations and waste streams of the vessel. The Garbage Record Book must record every discharge of garbage overboard and every delivery of garbage to a port reception facility ashore. Each entry must be signed by the officer in charge. The GRB must be retained on board for two years from the date of the last entry and produced to any authorised officer on request. Port State Control inspectors routinely request the GRB as one of their first documentation checks on commercial yachts. Incomplete, unsigned, or missing GRB entries are a common PSC deficiency that can result in vessel detention.
Discharge Rules by Waste Category
Each garbage category under MARPOL Annex V has specific discharge conditions. Knowing these rules precisely prevents inadvertent violations that can attract substantial fines. Plastics: Zero discharge, in all sea areas, at all times. No exceptions. This includes packaging materials, disposable tableware, synthetic ropes, fishing line, and any material mixed with plastic. The total discharge ban on plastics is the most important rule in Annex V and the most commonly misunderstood by superyacht guests. Food waste: May be discharged at 12 nautical miles or more from the nearest land when not comminuted (ground/macerated), with the vessel en route. If comminuted or macerated so that it passes through a 25mm screen, discharge is permitted at 3 nautical miles or more from the nearest land, en route. However, in Special Areas (see below), food waste may only be discharged when comminuted or macerated, at 12nm or more from the nearest land and en route. In no circumstances may food waste be discharged inside ports or marina basins. Domestic waste (glass, metal, paper, rags, crockery and similar refuse): Discharge prohibited in all sea areas. Cooking oil: Discharge prohibited in all sea areas. Operational waste (dunnage, lining and packing materials): Discharge prohibited in all sea areas. Incinerator ash and clinkers: Discharge prohibited in all sea areas; ash must be landed ashore.
Special Area Restrictions: Mediterranean, Baltic, and Others
MARPOL Annex V designates certain sea areas as "Special Areas" where more stringent discharge restrictions apply because of oceanographic conditions, ecological sensitivity, or high traffic density. For superyacht operators in the Mediterranean — the world's most popular superyacht cruising ground — this is operationally critical. Designated Special Areas under MARPOL Annex V include: the Mediterranean Sea; the Baltic Sea; the Black Sea; the Red Sea; the Gulfs Area (Persian Gulf / Gulf of Oman); the North Sea; the Wider Caribbean Region; and the Antarctic Area. In Special Areas, as everywhere else, the following are prohibited from discharge at sea: all plastics; all domestic waste (glass, metal, ceramics); all cooking oil; all operational waste; incinerator ash. What changes inside Special Areas is food waste: only comminuted or macerated food waste at 12nm or more from the nearest land, en route, remains permissible under the revised Annex V in force since 2013. For superyacht operators cruising the Mediterranean from May to October, the practical consequence is near-total onboard retention of all garbage for delivery to port reception facilities ashore. This requires careful waste management planning: adequate holding capacity, labelled waste segregation bins for guests and crew areas, and pre-arrival checks of port waste reception availability. Several Mediterranean ports have introduced advance notification requirements for vessel waste reception requests.
Port Reception Facilities and Pre-Departure Planning
Because at-sea discharge of most waste categories is restricted or prohibited, superyacht operators depend on port reception facilities (PRFs) for waste delivery. Under MARPOL Annex V, port states are obligated to ensure adequate port reception facilities. In practice, the quality, accessibility, and cost of PRFs varies significantly across the Mediterranean, Caribbean, and other cruising regions. Before departure from a port, the chief steward or captain should confirm: the next port's waste reception capability and opening hours; any advance notification requirements for waste delivery; the cost of waste disposal (varies from free at many northern European ports to significant fees at some Mediterranean marinas); and whether the vessel has sufficient onboard capacity for the planned leg. In remote areas, inadequate PRFs at intermediate ports may require the vessel to retain waste for longer legs. PSC and flag state inspectors check for evidence of garbage delivery: port waste receipts should be retained as supporting documentation alongside GRB entries. A GRB showing no deliveries ashore over a multi-month charter season in a Special Area will attract scrutiny. Operators should maintain a folder of port waste receipts corresponding to GRB entries.
PSC Inspections, Fines, and Reputation Risk
Non-compliance with MARPOL Annex V carries serious consequences. PSC officers from the Paris MOU (covering European and North Atlantic ports) and Tokyo MOU (Asia-Pacific) routinely inspect the Garbage Record Book as a standard check during any expanded inspection. Common deficiencies: no GRB on board; entries not signed; entries for plastic waste discharge; no Garbage Management Plan; GMP not in the vessel's working language; crew not aware of GMP procedures. Fines for MARPOL Annex V violations vary by flag state and port state. In the United States, MARPOL violations — including presenting a falsified record book to the Coast Guard — have attracted criminal prosecution and substantial fines against operating companies, with vessel detention and master imprisonment in egregious cases. European port states also impose administrative fines for serious violations. Vessel detention for unresolved MARPOL deficiencies disrupts charter schedules and has direct commercial impact. For high-profile superyachts, the reputational risk of a publicised MARPOL violation now exceeds the financial penalty. Social media and the maritime press give disproportionate coverage to superyacht environmental violations, reflecting the industry's visibility and the expectations placed on it by owners, guests, and the public.
