There are several styles of guide-ons
available, but all serve the same general purpose - to help you center your boat
on the trailer while loading by counteracting the effects of wind, waves, and
current.
Springs and other related hardware are prone to rust and corrosion, since they
are often submerged when on/off-loading your boat. Serious damage can and will
occur upon failure of a spring (your boat's shock absorber), U-bolts, or other
hardware.
