Buying Guide

What size boat and trailer frame do you have?

Choose guide-ons that match your trailer beam width and the hull size. Adjustable height options (40–48 inches, or longer bunk lengths) help accommodate varying bow heights and stern profiles.

What hull protection level do you need?

Carpeted bunks or padded PVC posts reduce hull wear during loading. If your hull is sensitive or valuable, prioritize models with protective padding and soft contact points.

Which material matters most for longevity?

Electro-galvanized steel offers rust resistance and durability in marine environments. Consider hot-dip galvanized finishes for enhanced corrosion protection in saltwater settings.

How important is visibility and guidance accuracy?

White PVC pipes provide high visibility for precise docking, while black pipes are less conspicuous. Choose based on typical ramp lighting, glare, and your boat’s color contrast to ensure reliable alignment.

What are installation and maintenance considerations?

Ensure mounting hardware fits your trailer frame up to specified dimensions. Periodically inspect for corrosion, bent components, or worn padding. Replace damaged parts promptly to maintain performance.
