Here's another way to approach the issue.
Create an "L" shaped "portable chock locater" from small stock, and bond it to the dedk, then make portable chocks to set in them for the dinghy. Add a couple of through-bolted pad eyes for mid-beam lashing, and one more to tie down the bow. The idea is to make the deck
still be foot friendly when the dinghy is in the water
. Our dinghy is a RIB
, and the 3 point tie works for it. However, you might like to carry your dinghy upright rather than upside down, and for that, people make cradles for them, rather than chocks.
