Re: Canvas rope - anchor bag

I would put a few grommets in the bottom of the bag to drain water out (AKA "anchor juice) and snake the bitter end of the line out one them. Run enough out to tie it off to something solid, casting an overhand knot on either side of the grommet will secure the bag and line together. I would also counsel against closing the bag with wet line inside, I've made that moldy mistake, leave it open to dry.
