Ancor's Marine Grade terminals differ from automotive terminals by being designed for the harsh marine environment. 
Nylon insulators are easy to crimp and will not split. Barrels are designed to tightly grip the wire with the least effort. 
Tinned copper gives the least electrical resistance but the most corrosion protection.
