tongue progress. made the little hoob-a-joob that will hold the boat from moving forward. the little "bar" was a pain with my 18 footer, i couldnt imagine with a heavy 21. so i put a winch on it, ill thread the strap through a hole, it will go over the bolt at the top which has a sleeve on the inside that rolls, and then it will hook to the boat.

ill also put a little piece on it with a "V" that will hold the front of the boat below the bow eye...
one of these...

and then of course ill have a safety chain as well.
