I scratched the deck of my kayak at a dock yesterday so am never going near another one! This thing had a step down with razor sharp angle iron (aluminum) underneath, just out of sight.
The refinish/ replace would sure be something to consider for a harder user, but probably not a concern in our case.
Thanks Dave.

: If you will be loading at dock, you might want to refinish or
: replace the outwales and being able to remove them would be
: necessary.
