Before you read
Most amenity write-ups skim the surface and leave you with the same answer for every boat. This one is built around the questions that actually move a dockage decision: how marinas measure your boat, how they bill, and which clauses to read twice before signing.
Pump-out service is required gear at any marina serving boats with installed heads. Federal law (the Clean Vessel Act) funded thousands of free or low-cost pump-out stations, but availability and reliability still vary widely.
Three formats exist. Dockside (you bring the boat to a pump-out dock), in-slip (a hose runs to your slip), and mobile (a service boat comes to you). In-slip is the gold standard for liveaboards; mobile is common in busy mega-yacht harbors.
Many municipal and state-funded pump-outs are free or nominal ($5–$10). Private marina pump-outs run $5–$25 dockside and $20–$60 for in-slip or mobile service per visit. Liveaboards often pay a flat monthly fee.
Reliability is the issue. A broken pump-out is the #1 marina complaint after Wi-Fi. Before booking long-term, verify the pump-out actually works and that the marina maintains it. A non-functional pump-out forces you to find another marina or risk a $2,000+ Coast Guard fine for overboard discharge.
