Seaplane Post-Landing Procedures

Slowly, into the wind or current — whichever is dominating my drift — because a seaplane has no brakes and no reverse.

• Coast in: plan the approach so the engine can be shut down early and the airplane coasts the last distance, arriving with just enough momentum to touch gently; if I misjudge, an idling engine and a dock full of people is a bad combination.
• Shallow angle: protect the wing and float from contact, and have lines and fenders ready.
• Wind onto the dock: aim short and let the drift carry me on.
• Wind off the dock: come in a bit steeper (Seaplane Handbook FAA-H-8083-23 ch 6).

Mooring buoy: a permanent anchor point — I approach it into the wind at idle, shut down and coast the last stretch, and secure the bow line to the buoy (approaching slightly to one side so the buoy stays visible past the nose). Safer than my own anchor because the tackle is (presumably) engineered for the load.

Anchoring: I supply the ground tackle. Pick a spot with the right depth, good holding bottom, and enough swing room for the airplane to weathervane through a full circle as wind shifts; lower the anchor and pay out generous scope — several times the water depth of line — so the pull on the anchor stays horizontal. Then confirm it's actually holding with shore references before shutting everything down (PA.XII.B.S1, FAA-H-8083-23 ch 6).

Adequate scope is the whole game — short scope lets the anchor break out. Use line and anchors sized for the airplane and expected weather, consider a second anchor for overnight or shifting winds, and think about what changes while I'm gone: tide (depth and swing radius change), forecast wind, and boat traffic and wakes. The ACS language is explicit: enough anchors and lines, of sufficient strength and length, considering movement, depth, tide, wind, and weather changes.

Know the bottom first — walk it, ask, or read the water color; sand and smooth gravel are friendly, rocks and shells eat float bottoms.

Approach: nose-in at bare steerageway, shutting down before the water gets shallow enough to strike the water rudders or prop, and let momentum slide the float bows gently onto the shore. In wind blowing offshore, or with a rising or falling water level, I often prefer to turn and back in tail-first (sailing backward onto the beach) so the airplane can be walked off easily and waves don't slap the tail.

Then secure to something solid above the waterline — and account for water level changes so I don't return to a floating (or stranded) airplane (FAA-H-8083-23 ch 6).

A ramp approach is nose-first with enough momentum (or a touch of power) to slide the floats or hull up the ramp surface, then immediate shutdown per local procedure. For an amphibian using a land ramp: gear per the ramp type and POH, and the second I'm on pavement, all the land after-landing rules of Task XII.A apply — parking with prop blast in mind, checklists, securing. The gear-position discipline runs both directions: wheels for pavement, wheels up for water, verbally confirmed every time.

Everything from XII.A plus the water-specific items:

• Pump the floats — each compartment gets checked and pumped because slow leaks are normal and an unnoticed flooded compartment can sink or flip the airplane at its mooring.
• Inspect float bottoms and spreader bars for damage from debris or the beach.
• Rinse with fresh water after salt operations (corrosion is relentless).
• Check the water rudder cables and hinges.
• Document any discrepancies just like on land.

If the airplane stays on the water, the securing checklist assumes weather will change — because it will (FAA-H-8083-23 ch 6).

Propeller stopped before anyone unbuckles — briefed in advance. Docks are slippery and floats more so; I direct the exit path, one person at a time, stepping where I say (float decks have walk areas; the wrong step goes through a hatch cover or into the water). Life vests stay on until everyone's on solid footing if that's the operation's rule. At a beach, passengers exit on the shore side, away from the prop even though it's stopped — habits transfer. Then I monitor them on the dock or ramp; a seaplane base has boats, props, and water as simultaneous hazards (PA.XII.B.R4).
