Will: Some months back you were discussing making some alterations to your trailer suspension. Did you remove the helper springs from your trailer and did it help? I have a Carnai trailer made for the Hobie 18. With the Blade on cradles and travelling at 55 mph, I observe considerable up and down movement of my bows on cement pavement. The rig rides a lot smoother on asphalt surfaces. The movement seems to be caused by the flexing of the trailer tongue and frame as it absorbs bumps rather than the springs. I'm thinking of making two adjustments, take the smaller leaf off to soften the springs and moving the axle forward to move it closer to the mainbeam of the boat. That should reduce the hobbyhorsing effect I'm seeing in the rear mirror. I've attached a side view photo of rig to give you an idea of the trailer as currently configured. Anybody have similar experiences? John D.
