The best pressure washers for boats allow you to clean the hull without damaging the finish. Read on before you pull the trigger in your search for the right machine. I used a Karcher appliance with the patio cleaning attachment placed on the roof of my boat and I have obtained excellent results. It cleans all the green dirt from the non-slip sand surface without greasing your elbows.
The advantage of a heavy-duty pressure washer is that you can also use it for a variety of household tasks, from cleaning the house to removing dirt from a concrete entrance. If you use a jet washer, be prepared to clean adjacent boats in the marina of any dirt you might throw on them. I saw a guy in the Ashby doing a good job with his battery-textured roof, pressure washing and tap water. This is by far the best pressure washer I have, or have ever had, and I've had quite a few over the years.
If you want the convenience of an electric pressure washer but need more power, check out the Sun Joe SPX3000. Yes, that's the problem with using a pressure washer, but it shouldn't work as long as you keep the end of the lance a couple of feet away from the surface you're cleaning and remember to keep it at an angle. I think the paint would be very bad if you removed it, even the Northwich high-pressure one won't remove the rotten paint. For those who do need the power, the Simpson MegaShot has a pressure of 3,200 psi at 2.5 gallons per minute.
These powerful tools are generally rated based on pounds per square inch of pressure (PSI) or gallons per minute (GPM) of water flow. A medium-duty pressure washer between 1500 and 2800 psi will handle most household tasks, and yet it will allow you to wash your boat with confidence if you use wide-angle tips, which apply lower pressure. At just 31 pounds, it's lighter than most gasoline-powered pressure washers for boats, but with comparable pressure. If the OP is looking for a cheap pressure washer, he would do well to forget about the luxurious Kaercher stuff and buy a decent Chinese imitation.
A pressure washer is the best way to remove marine life, algae, oil stains, water discoloration and other types of dirt that endanger the finish of the vessel. This pressure washer comes with an adjustable pressure button for a wider range of applications: simply raise it for household tasks or lower it to clean boats and cars.
