They let you buy one of their boats? Amazing.
That aside, I'd suggest coating the bottom with something slippery, then getting Cataract oars about 1 1/2' longer than 1/2 the length of your boat. Do not get "second choice" oars, they can kill you. Buy the best brass or stainless oar locks, or I'll give you a set. Keep the pointed end downstream and always wear your PFD. (your mother)
