    How to setup trailer bunks-gctid821364

    Anybody have a clue how to setup bunks for a specific hull?

    Are all 18* deadrise cruisers same basic bunk alingment? Other than landing on a keel maybe.

    I need a triple axel trailer and my friend has one but its set for a go fast boat which is a different hull type. Wondering if i can move the bunks and make it work.

    A photo of the trailer at minimum would help, and to know what brand.

      I layed out the deadrise on a piece of 2 inch rigid foam insulation . Then I cut it and used it as a form to fit the bunks to the angle of the boat bottom.

      You can use the form to move fore and aft on the trailer to verify your angle and boat height from the ground fenders and center clearance at the cross members.

      If you got the angle right it should fit right on. You can also mark the chines on the foam to see where the bunks will lay according to the boat

        Problem is the boats in the water theres got to be factory information on this. I found a web article that was pretty excellent but it involved taking measurements of the transom and pulling out and in several times to make adjustments.

          Assuming that you are buying this trailer...... the proper method:

          Get the hull onto the trailer.

          Raise the hull with crib stands. 2 at just ahead of mid-ship, and 2 at the transom area.

          Level both the hull and the trailer frame.

          Adjust the bunks to fit the hull accordingly.

          Some are adjustable with fasteners..... some require blowing and re-welding.

          Done!

          And by the way...... with a triple axle trailer, steer clear of Torsion Axle suspension!

          Go with Leaf Sprung suspension.

            If my friends trailer is adjustable maybe ill pay for a hull out and see what they charge to set the trailer for me...

            I forgot about this method! Thanks

            And yes the hell with torsion axels.. they scare the crap out of me
