The thing I like about tricing lines is the redundancy. I have a tender fall twice:
1. The spreader at the front snapped (the PO had made it from something like Starboard--stupid, so I made a new one from aluminum square tube), dropping the front while sailing single handed in a big wind single handed. I grabbed the painter, clipped that to the boat, lowered and then cut the back end loose, and towed it to more sheltered water. No harm done, but there could have been.
2. The webbing on the back chafed through on a hidden sharp spot. This time I had the chute up, so even slowing was nearly out of the question. Dropping it in the water would have been unsafe at speed. I went down the sugar scoop, attached a new line looped over the davit, and winched it back up. A safety tether was required.
Now I always trice it up. Unlike a strap that pulls it in, the tricing lines will hold the dinghy even if any two lines fail. You may never have a line failure... but I bet you will if you sail long enough. All it takes is one loose shackle pin, bit of chafe, or a failed dinghy eye....
