    What will hold the nose of the ski down when the trailer is bouncing along a rough road?

    Will there be a separate strap pulling downwards from the bow eye to the frame?

    Hmmm. I would be concerned about using a rigid link between hull and trailer. Trailer frames flex, wiggle and move around under the ski. Road impacts on the trailer wheels can ripple and telegraph through the trailer frame with some violence.

    A fabric strap has some amount of give or stretch to allow for some motion between hull and trailer while a metal hard link will have minimal give.

    Have you used this metal link method on previous trailers?

    Another concern I would have is the downward link and bow V support does not appear to provide much resistance to forward motion of the hull. If there is a sudden deceleration (hard braking or tow vehicle collision) it looks like the hull could shift forward and ride up over the bow support.

    Personally I prefer to have the bow roller (or vee block) very high, tucked right under the rub rail at the nose. The hull bow eye would be below the bow roller so the winch strap can pull forward and downwards. The hull cannot move up, down, or forward. And of course cannot move rearwards. The winch strap alone provides all these. The safety strap provides a secondary backup function only, the winch strap alone is enough to hold the hull in position.

    In South Africa PWC/Boat trailers are rigid over-engineered steel frames which do not flex or bend.

    We have to drive allot of off road (gravel) and never had a ski move or bounce or shift.

    This particular trailer was built to carry 1800 KG... around 4000lb with 15" wheels rated for 2400 KG.

    I've personally used the metal links and this hull stopper system for the last 20+years with all my jetski and boat trailers.

    Pretty much this is how all the trailers are in South Africa.
