Buying Guide

Match material to exposure

Choose UV-stable polyethylene for long-term outdoor use or marine-grade vinyl for flexible, impact-absorbing bumpers depending on sun and saltwater exposure

Pick the right shape and location

Coned piling caps protect vertical pilings while corner bumpers and keel guards are designed for hull contact and corners—select form by where your boat contacts the dock

Consider attachment method

Look for piling caps that fit securely over posts and inflatable or strap-mounted bumpers for adjustable placement and easier installation

Check protective features

Seek products with bird-deterrent tags or reinforced edges to prevent abrasion and nesting, and keel guards specifically sized for fiberglass or aluminum hulls

Balance rating and value

Use user ratings (many top picks have 4.7–5.0 stars) alongside price to gauge overall value for under $100 purchases
