The boat ramp is where boating and driving meet, and it can be one of the trickiest parts of a day on the water. Drivers back a heavy trailer down a slippery slope, often with a line of impatient boaters waiting. Mistakes are common: a forgotten drain plug, a boat that slides off early, or a tow vehicle that rolls into the water.

A calm, step by step routine prevents most problems. This guide covers how to launch and retrieve safely.

Before you leave home

Towing a boat starts with the basics in our towing guide: the right hitch, crossed safety chains, working lights and correct tire pressure [1]. Then add a few boat specific checks:

  • Practice backing the trailer in an empty lot
  • Make sure the winch strap and bow eye are in good shape
  • Pack the drain plug, dock lines, fenders and life jackets
  • Check the trailer’s wheel bearings for heat and noise

Prep in the staging area

Most ramps have a parking or staging area nearby. Do your prep there, not on the ramp, so others can keep launching [2, 3].

  • Install the drain plug [2, 3]. Forgetting it is a common cause of a boat filling with water.
  • Remove the straps at the back of the boat. Leave the bow winch strap attached [2, 3].
  • Unplug the trailer’s light plug from the tow vehicle, so lights do not short in the water [2, 3].
  • Load gear, attach dock lines and fenders, and put life jackets on children.
  • Feel the wheel hubs. If they are hot after a long tow, let them cool. Hot bearings dunked in cold water can pull in water [2].

Backing down the ramp

1. Line up straight with the ramp lane. Use a spotter if you can [3].

2. Back down slowly. Keep your hand at the bottom of the steering wheel: move your hand the way you want the trailer to go.

3. Stop when the back of the boat just begins to float [2]. A common guide is water about halfway up the trailer wheel hubs [3].

4. Put the vehicle in park and set the parking brake [2]. Chock a rear wheel of the tow vehicle if the ramp is steep or slick [3].

5. Unhook the winch strap and safety chain, and float or motor the boat off [2, 3].

6. Pull the empty trailer up the ramp and park in the trailer lot.

Warning: Never stand behind or between the trailer and the water while the vehicle is moving. If the vehicle starts to slide on a slick ramp, do not try to stop it with your body.

Keep the tow vehicle out of the water

  • Do not back in too far. Water near the tow vehicle’s exhaust or doors means you are too deep. Deep dunking also damages bearings and wiring [3].
  • Watch for algae. The lower part of many ramps is slick. Two wheel drive vehicles can lose traction pulling out. Use four wheel drive if you have it.
  • Keep the driver in the seat with the parking brake set when possible, especially on steep ramps, while another person handles the boat.
  • Never leave the vehicle running in neutral on a ramp.

Retrieving the boat

Reverse the launch steps [2]:

1. Bring the empty trailer down to the same depth.

2. Set the parking brake and put the vehicle in park.

3. Drive or winch the boat onto the trailer. Hook the bow strap and tighten the winch, then attach the safety chain [2].

4. Pull slowly up the ramp to the staging area.

5. Pull the drain plug, attach the rear straps, plug in and test the trailer lights and raise the motor for travel.

6. Remove weeds from the trailer and boat. Many states require this to stop invasive species.

Ramp manners are safety, too

A crowded ramp leads to rushing, and rushing leads to mistakes. Keep the ramp clear, take turns and stay aware of people walking and children playing nearby [3]. Do not let kids play on docks next to the ramp lanes.

Checklist: boat launch routine

Checklist from Safety Behind the Wheel Foundation

  • Trailer hitched, chains crossed and lights working for the drive
  • Wheel hubs cooled after a long tow
  • Drain plug in
  • Rear straps off; bow strap still on
  • Trailer lights unplugged before backing in
  • Parking brake set and vehicle in park before anyone gets out
  • Life jackets on children and weak swimmers
  • Weeds removed before leaving the ramp

Frequently asked questions

How deep should I back the trailer?

Until the boat’s stern just floats. Many boaters use the guide of water about halfway up the trailer wheel hubs. Check your trailer type, since bunk and roller trailers differ.

What if my vehicle starts slipping on the ramp?

Use a low gear and gentle gas. Four wheel drive helps. If it keeps slipping, have the boat moved and get help. Never push a sliding vehicle by hand.

Should I disconnect the trailer lights?

Yes. Unplug before backing into the water so the lights do not short out. Plug in and test them before you drive home [2, 3].
