The Pre-Departure Double Checklist: A 12-Minute Routine That Prevents 90% of Mishaps on a Boat or an RV (and the One Step People Always Skip)

Every memorable day on the water or the road starts with the same thing for us: 12 focused minutes. Two quick passes—one setup, one hands-on—catch the dumb mistakes before they become expensive problems. We’ve run this routine on both sides of our life: leaving a marina aboard our 74-foot Hatteras motor yacht, Empire, and pulling out of a campsite with the tow rig ready to roll. It’s not glamorous, but it’s exactly what keeps the adventure fun.

Why the “double” works

• Single checklists rely on memory; the second pass relies on touch. That’s the difference between “looks good” and “is good.”
• It’s fast. Six minutes to set systems, six minutes to verify. No overthinking, just flow.
• It prevents 90% of the mishaps we’ve personally made or witnessed: dragging cords, open hatches, mis-set valves, missed pins, unlatched compartments, and unsecured gear.

The 12-minute routine at a glance

Two passes. Same logic for both a boat pre-departure checklist and an RV pre-departure checklist.

Pass 1 (6 minutes): Systems Prep

Boat (dockside):

• Power and fluids: shore power off and stowed, water hose disconnected, fuel and water levels checked, generator status confirmed.
• Engine room: quick hands-on leak and belt check, seacocks in correct positions, bilge dry, strainers clear.
• Nav and comms: plotter up, VHF on correct channel, AIS/lights set for conditions.
• Deck and tender: fenders staged for departure side, dinghy drain plug in, anchor locked, anchor locker latched.
• Interior secure: hatches and ports dogged, galley secured, cabin doors latched, loose gear stowed.

RV/Tow (campsite):

• Utilities: power unplugged and stowed, water and sewer disconnected and caps on, propane set, water heater off if needed.
• Slides, jacks, and steps: slides in and locked, stabilizers up, steps stowed, awning locked.
• Hitch and tow: ball height/right drop, coupler seated, pin/clip installed, weight distribution bars on, safety chains crossed, breakaway cable attached, 7‑pin connected.
• Brakes/tires: trailer brake gain set, tires and visible lug indicators checked, mirrors and cameras on.
• Interior secure: cabinets latched, fridge locked, cargo tied down.

Pass 2 (6 minutes): The Hands-On Departure Check

This is the walkaround where you physically touch every point that can bite you.

Boat:

• Tug-test every line, fender, and cleat. Confirm spring lines last to release.
• Physically pull on shore power plug and water hose—are they onboard and stowed?
• Hand on each hatch, port, and locker latch; verify anchor safety pin or chain stopper is engaged.
• Glance at exhaust water flow on start, smell for fuel, listen for belt squeal.
• Final bow-to-stern look: antennas down or up as needed, dinghy secure, nav lights actually on.

RV/Tow:

• Tug-test hitch coupler, verify latch locked and pin installed, safety chains tensioned, breakaway cable independent of chains.
• Pull-test trailer brakes at low speed; confirm gain and function.
• Hand on every exterior latch, bay door, slide lock, and vent cap.
• Check steps, awning locks, TV/radio/Starlink antennas, bikes and cargo straps.
• Walk back and count: chocks stored, wheel leveling blocks packed, caps on all ports.

The one step almost everyone skips

The second pass. People do a visual, then get distracted by neighbors, lines, traffic, wind, or excitement—and they leave without the tactile walkaround. The hands-on check is where you catch:

• A coupler that looked seated but wasn’t actually locked.
• A dock line still looped around a cleat under the rail.
• A dinghy plug missing, a livewell valve open, or a seacock in the wrong position.
• An exterior bay door that “looked” closed but wasn’t latched.
• A 7‑pin that’s half-in, a breakaway cable clipped to a safety chain instead of the frame.
• A shore power cord hiding under a fender (ask us why we touch that twice).

Make it a ritual: nobody casts off or puts the truck in gear until the hand-check is complete and called out.

Common gotchas this routine catches (before they cost you)

• Boat: shore power still connected, raw-water seacock closed on startup, anchor not secured, fenders stowed too early, tender painter in the prop, flybridge hatch ajar, lines fouling the rudder.
• RV: stabilizers up but steps out, antenna up, fridge unlatched, cargo bay open, sewer cap off, equalizer pins missing, brake gain at zero, chocks left behind.
• Both: unsecured loose gear, poor weight distribution, tools left in the engine bay, vents/ports open to rain, wrong lights for conditions.

Pro tips to make the 12 minutes stick

• Assign roles. One person runs systems, one runs the hands-on pass; swap weekly to stay sharp.
• Call-and-response. “Shore power off?” “Off and aboard.” “Hitch pinned?” “Pinned and clipped.” It sounds formal because it works.
• Start clean, end clean. Stow the checklist where you can actually grab it: helm, driver door, or on a lanyard.
• Wind and crowds = slower, not faster. Add a minute to plan line order or exit route.
• Night variant: headlamp, red light in the engine room, extra focus on nav lights, reflectors, and brake function.
