Guide-on posts make it easy to load your boat onto your trailer and back your trailer down the ramp. They attach to the rear of your trailer and extend out of the water, providing visual targets to center the boat between during loading.

Guide Your Boat Into and Out of the Water with Ease
When your boat trailer has been backed down the ramp and is partially submerged, these 40" tall guideposts that are mounted on the rear corners of the frame will stick out of the water, giving you 2 highly visible targets to guide your boat between for loading. The PVC pipes also provide a visual aid to help you back your boat trailer down the ramp when you're unloading and loading your boat.
Installation
The posts are simple to install. Slide the PVC pipes over the pre-galvanized steel support posts. Then mount the posts on the top or below the trailer frame, as close to the rear corners as possible. Adjust the posts so that the distance between each post and your boat is less than 1".
Pre-Galvanized Steel
Pre-galvanized steel parts are stamped from a sheet of steel after it has already been galvanized. The edges of pre-galvanized parts often lose their zinc coating during the stamping process. Because of the thinness of the coating (less than 1 mil) and the fact that the edges remain exposed, pre-galvanized parts can begin to oxidize and rust quickly, so it's recommended that they be primed and painted.

My trailer has very skinny rails open on one side. If yours is this way, I advise cutting a block of pressure treated wood to just fit in the rail with a few hammer blows. Otherwise the shackles of these guides will bend the open ends inward, causing them to loosen. This isn’t a problem with this product, it’s just my cheapo trailer not being made of 4 sided box channel. Everything still looks new!

It is outstanding for loading. It helps guide you in a straight line when trailer is below water line.

We do have some u-bolts that are 5-1/4 inches long, and those are available as # 382385UB.

These work extremely well when loading in windy weather - the boat stays in place making it easy for one person to load.

This has worked out well. Lights and connections never touch the salt water. I did the same thing on the trailer for 25 center console.

After one year the guides are working great. The guides are a great help when Im loading the boat onto the trail by myself. Great investment.

That's good to hear, John! Being able to see when back up on a slope is a big game changer. Also, I really like your boat!
