UHMW Bottoms

Let High Caliber add a custom Ultra High Molecular Weight bottom (UHMW) to your aluminum-hulled riverboat using the latest bolt-free attachment system. Using our alumiweld attachment system, we’ll rotate your boat hull up and custom fit UHMW-Polyethelene (plastic) panels to the contact area of your hull in order to create an ultra slippery and durable bottom that will give you the ability to slide over gravel bars and bounce over rocks with minimal damage.

What are the advantages of a UHMW bottom?

  • Slide over obstacles (gravel) with ease
  • High tensile strength disperses sudden impact
  • Self lubricating which means less friction
  • Reduces wear of your hull and protects your investment
  • Won’t create pitting of your expensive aluminum hull like a steel QT plate will. NO RUST!
  • UHMW is lightweight and abrasion resistant, far outlasting steel in commercial applications
  • Can be replaced and repaired with greater ease than other hull protection methods

The High Caliber Bolt-Free Method: No bolts. No Holes. No leaks!

  • Can be added to any aluminum-hulled boat, without removing the interior
  • Is less expensive than keel plate/tap methods
  • Does not require bolting through your hull
  • Only costs a fraction compared to the bonding glue system
