The hull is made of aluminium. Aluminum is strong and forgiving. Where an impact on a fiberglass hull will result in major gelcoat damage and possible cracking, an aluminum hull will probably only have a scratch or a small bend. The only concern is electrolysis. Ensure that you have proper sacrificial anodes installed.
