The Vulcan or Ronca should be fine. You want to pull out all of the rode. If you are not getting water under the bunk or floor platform, the locker should be fine. I found that the 25's seem to have less problems with the anchor locker than the 22's.
When you get the bitter end of the anchor rode out--take some light line--1/8" to 1/4" and tie one end to the eye bolt nut which should on the inside of your bow eye. If none, then get a 1 x 2" stick several inches long and tie the thinner line to it. then take that to the end of the rode--best to make a very tight back splice and then put a pass or two of the thin line thru the bitter end of the main line-don't tie a monkey's fist. You ant to be able to get that line out of there. if you need it, either to tie a fender to it, for temporary abandonment, or if you need to add more anchor line. (Put multiple red marks (electrical ties, paint, plastic dip on the last 3 feet of the anchor rode to the bitter end, so you can stop before you get to the thin line. If you need to sever the line, then the thin line is easy to cut, and then tie two bowlines to join two anchor rides together.
