Whatever style you require, we most likely have a jack to meet your needs. Other considerations include the amount of 'travel', which is the jack’s up/down movement in inches and the maximum height of the jack. These can be powder-coated steel, anodized aluminum or zinc-plated steel. Saltwater boaters need jacks that are corrosion resistant. You should also consider where you use your boat. Large diameter wheels tend to move more freely than small diameter wheels, especially over uneven terrain. If your boat is light enough, a jack with a caster-style wheel will allow you to move the trailer around, which can help when you are hooking the trailer up to the tow vehicle. If your boat is too heavy to move around manually, then a jack with a foot will work well.

You will also need to decide between a jack with a foot or a wheel. We carry a variety of trailer jacks with the heaviest models capable of supporting tongue weights up to 5,000 pounds. The trailer jack you choose must be rated to support the tongue weight of your trailer when loaded with your boat. What to Consider When Buying a Trailer Jack Whether you use your boat in saltwater or freshwater, you'll find a trailer jack that is perfect for your specific needs at West Marine. Fortunately, we carry a wide range of jacks suitable for different boat weights, applications and environments to get you back on track quickly if your trailer’s jack bites the dust.

So unless you happen to be an Olympic power lifter, you might not be able to hook up if your trailer jack fails. Depending on the loaded weight of the trailer, the amount of weight that the jack supports can be considerable.

Trailer jacks are seldom thought of but an absolutely necessary component of your boat’s trailer. Is Your Boat’s Trailer Jack Ready to Fold?
