Buying Guide

Match guard shape to your keel profile

Measure keel width and contour—flat, rounded, or V-shaped guards perform differently depending on keel geometry and contact area

Check material compatibility

Choose guards that specify compatibility with fiberglass and, if relevant, aluminum components to avoid galvanic issues or abrasive interactions

Evaluate attachment method

Compare bolt-on, adhesive, and strap systems for ease of DIY installation, adjustability, and long-term hold under wet conditions

Prioritize abrasion resistance

Look for durable outer skins and impact-absorbing cores that resist scuffing and distribute contact forces to protect fiberglass gelcoat

Balance cost with features

Consider price tiers—budget options under $100, mid-range around category averages, and premium guards above $200—based on expected service life and fit
