Buying Guide

What matters most when choosing bow bunks?

  • Hull compatibility: Check bunk length and contact area to ensure full hull support without overhang.
  • Material and corrosion resistance: Aluminum, stainless steel, and galvanized steel each offer different durability profiles in saltwater and freshwater use.
  • Installation options: Look for adjustable or swiveling brackets for easier alignment during loading and unloading.
  • Trailer compatibility: Confirm beam size and crossbar spacing match the bunk brackets’ specs.
  • Protection for the hull: Consider carpeted or padded bunks to minimize scratches and dents during transport.

What setup suits which trailer types?

  • Swivel top brackets: Best for trailers where hull alignment varies between launches or where quick adjustments are needed.
  • Longer 14″ bunks: Better for heavier boats or boats with wider bow profiles requiring extended support.
  • Bow rest catchers: Add an extra contact surface on 3″ tongue trailers to reduce hull movement at the bow.
  • Carpeted bunk kits: Ideal for delicate hull finishes and frequent launching on diverse trailer frames.
  • Galvanized brackets: Suitable for marine environments where rust resistance and longevity are priorities.
