Here are two 18 footers. They both look really nice. The guy who owns the one with the bracket told me that he's willing to sell the boat minus the trailer at a lower price. I think he lives near water so getting it on another trailer shouldn't be a big deal. I also asked about the hole above the bracket and he assured me the wood is glassed in for whatever that's worth. Have a looksy:
