DSC00403 This is my 23' Long Trailer when I first brought it home. Unfortunately Long went out of business shortly after I bought this trailer. Such a shame. It too bad that some company somewhere can't manufacture the extension brackets for those bunks because they are the best I've seen on the market so far and they easy to adjust with the aid of a couple of jacks with the boat sitting on the trailer. That's how I adjusted all my brackets after I got the proper tongue weight, but that's another story. This trailer came with a thick rug covered keel board and I told the dealer to keep it. What you see in the pic is a couple of pressure treated sandwiched 2x10" planks held to the cross members with a couple of galvanized brackets that were given to me by the city power company. I picked up two brackets which are nothing more than a back strap, two 5/8" X 6.5" carriage bolts with washers and nuts. I have the carriage bolt heads counter sunk below the surface of the top plank where the keel sits. This insures that the keel won't hit the bolt heads. The plates bolt up against the bottom of each cross member. The only holes I have bored are through the wood planks and not the cross members. This works out great because I can loosen the carriage bolt nuts to loosen the back plates and be able to slide the keel board to one side or the other. I do this when I take my boat off the trailer in my yard and place her on boat stands, but that's another story. Those two guide that came with my trailer are great for centering my boat when I'm loading her on the trailer at the YC boat ramp. Some guys install keel guides but these guide are all you need, really.
