Definition
Designated areas on water used for the takeoff, landing, docking, and servicing of seaplanes. Seaplane bases may be public or private and are listed in the Chart Supplement with information on water lanes, depths, hazards, and available services.
Plain English
Places on lakes, rivers, or coastal water that are set up and recognized for seaplanes to operate from, the way airports are set up for landplanes.
Context Anchor
Seen in airport and facility information, chart supplements, and Notices to Air Missions when a water landing area has a closure, hazard, or service change.
Why Pilots Care
Pilots consult seaplane base information to confirm operating hours, hazards, and availability before water operations.
Intuition Check
Do not read “base” as only a military base or company headquarters. In this term, a base is an operating location set up for seaplanes.
Example Sentence 1
Before departing for the lake, the pilot checked NOTAMs for the seaplane base and noted a warning about submerged debris near the south water lane.
Example Sentence 2
Seaplane bases usually include ramps and tie-downs for launching and securing aircraft.
