Is Fiberglass damaged by impact or contact with rocks and gravel more severely than aluminum?
No. If contact is made with a surface that damages a fiberglass boat, similar damage would occur to an aluminum. Key to this issue is the fact that fiberglass can be easily and cosmetically perfectly repaired after a collision. Aluminum, in many cases, cannot. A simple keel guard can remove the worry about cosmetic damage from placing your Tuffy up onto rocks or gravel.
