Almost nothing on this page is difficult. The reason ramps go wrong is that people do the easy things in the wrong order, in front of an audience, with a queue building behind them — and then start improvising.
The order is the whole skill.
Ready the boat before you back down
This is the step that decides everything after it. The Minnesota DNR is specific: "Ready the boat at the make-ready area, before you back down the ramp." Their list is four items:
- "Remove all tie-downs except the bow winch strap."
- "Tilt up your motor or stern drive."
- "Be sure your drain plug is in place."
- "Disconnect the wiring plug between vehicle and trailer."
Every one of those takes seconds in a car park and is miserable on a wet slope with someone waiting. The drain plug in particular is the classic: it is the one item on the list you cannot fix once the boat is in the water, and the consequence of forgetting it is not embarrassment, it is a sinking boat on the trailer.
If the ramp has no marked staging area, do this in the parking area anyway. The ramp itself is not where you get ready.
Two people, if you can — and especially in current
The Minnesota DNR recommends the buddy system: "Two people are recommended for boat launching, especially in river situations where there is a current—one in the boat and one in the vehicle."
That is not about lifting. It is about the moment the boat comes off the trailer: in current or wind, an unattended boat starts leaving immediately, and the person who could have stopped it is thirty feet away in a truck.
Back in until it just floats
The instruction is precise, and precise is the point: back the trailer "down the ramp and into the water until your boat just floats (varies by boat and trailer)."
Just floats. Not until it lifts clear, not until the trailer fenders vanish. Too far and you are reversing a vehicle down a wet slope for no reason, and the trailer can find the drop-off at the end of the ramp.
Then, in order
From the boat, the Minnesota DNR's sequence is:
- "Lower and start the motor."
- "Release and unhook the winch (this should float the boat)."
- "Slowly operate the boat away from the trailer, then be ready to use more engine power to keep the boat under control (maintain steerage) in the current and wind."
Note the third one. Idle speed is enough in still water and is not enough in a river. The moment you are free of the trailer you may need power to hold a line, and that has to be a decision you have already made rather than one you make while drifting toward something.
Then: "Find a safe place to pull up to shore to pick up the operator of the vehicle as river sites often do not have docks." Rivers are not lakes. Do not assume there is a courtesy dock to hold against while your partner parks.
Getting it back on the trailer
Launching is the part people worry about. Retrieval is the part that destroys ramps.
The Oregon State Marine Board defines the problem: "Power loading is when a boater remains in their boat and keeps the motor trim low to 'power' the boat onto the trailer." It is quick, it feels efficient, and it is why so many ramps have a step at the bottom.
Virginia DWR explains the mechanism: "the prop wash created from power loading will erode a hole at the end of the ramp, which will cause a sharp drop-off and can undermine the end of the ramp."
Then it comes back for you. Once that drop-off exists, "trailer wheels are then backed off the end of the ramp that has a drop-off, the trailer can hang on the end of the ramp causing damage to the trailer as the wheels are pulled back up onto the ramp." The person who power-loaded on Saturday digs the hole that strands somebody's trailer on Sunday — and eventually their own.
The cost is not small. The Oregon State Marine Board: power loading "causes damage to the toe of the boat ramp that requires costly repairs and may damage your trailer", and undermining the toe "compromises the integrity of the ramp itself, causing damage to the rebar and other material on the ramp." From there, "this can cause boat ramps to be shut down", and "in many cases, the boat ramp requires a complete rebuild that costs hundreds of thousands of dollars."
This is not theoretical maintenance. Virginia DWR notes they are "frequently adding riprap to the end of ramps as temporary repairs for the problems caused by prop wash."
What to do instead, in the Oregon State Marine Board's words: "Get out of the boat, get onto the boarding dock, and 'walk and guide' the boat onto the trailer using a bow line."
It takes longer the first time and no longer at all after that. And it is the difference between a ramp that is there next season and one that is closed for a rebuild.
Before you leave the water
Ramps are where aquatic invasive species move between waters, and at many of them the check is mandatory rather than advisory. At Curecanti, boaters are told to "Turn your vehicle off, set the parking brake, exit the vehicle, and answer the inspector's questions."
The decontamination steps Curecanti lists are worth doing everywhere, inspection or not: follow "Clean, Drain, Dry" procedures, "pull bilge plugs; turn on bilge pump(s), drain compartments that could store water such as live wells, bait wells, and ballast systems; check anchor(s) or other equipment that touched the water."
Anything holding water is a way for something to hitch a ride to the next lake. A live well is the obvious one for anglers, and the one most often forgotten.
Paperwork, and the things a ramp check looks at
Registration and equipment requirements are set by federal rule and by your state, they vary by vessel, and they change — so this guide links rather than restates them. Our course covers how registration and numbering work in Vessel Registration and Numbering, and your state agency publishes the current specifics.
Tell someone before you go
The FWC puts it in one line: "Let family and friends know where you are going and when you expect to return." Their reasoning is the same as ours — "the sooner rescuers can locate an overdue boater, the more likely the outcome will be positive."
That is a float plan, and the ramp is the last convenient moment to send one.
And check what you are launching into
- Trip planner — wind, sea state and any advisory as a single go or no-go call for your launch point.
- Tide times — if the ramp is tidal, the state of the tide decides whether it is usable at all when you come back.
