    Bunk spacing, how do I set my trailer bunks up to best match my hull?

    What does everybody consider the best way to have the bunks on the trailer?

    So ski rides with bunks on bottom or higher up or any other ideas.

    I plan to set mine either side of the ride plate, any comments?
    Thanks

    This has been covered in previous threads.

    In general you want the bunks to not be under the chine ridges of the hull, but on the flat areas beside the ridges.

    In general, the farther apart the bunks are spaced the more stable the hull will be when the trailer is bouncing down the road. Narrow bunk spacing can allow the hull to wobble side to side as the trailer flexes and bounces.

    Depending on the trailer and the hull shape, you may be limited as to how far apart the bunks can be positioned as wider spacing sets the hull lower. You do not want the hull to strike a trailer frame cross bar when launching or loading the trailer at the ramp.

    So you say not by ride plates but as high on the boat as we can. Avoiding bottoming out on trailer.

    Thanks,

    I did look to see if this was on the site but failed to find it.

    In addition to bunk width, it is important to set the bow winch position correctly (which determines the trailer tongue weight at the hitch ball) and to set the bow roller height to properly meet the hull above the bow eye.

    Search in this forum for
    Bow Roller
    Tongue weight
    Bunk spacing

    Should come up with some good threads.

    when setting height the easiest way I have found over the years......You will need a jack....
    Set ski on the trailer.
    Take a piece of wood an inch or two thick and lay it on the cross members.
    Lower the bunks so the ski is resting on the wood on the cross members.
    tighten the bunk supports.
    Jack ski slightly to pull the wood out and lower back on the bunk.
    Now your spacing height is perfect from the cross members.
