Aloha Chris,
Looks perfect. So you'll make a two part sling for your
dinghy with attachment points on midway bow and stern so it is really easy to flip upside down when you get it inboard your
lifelines and over your dinghy chocks. Your dinghy sling will be on a small block and tackle between boom and dinghy sling. If you have a loose footed main you can just make up a strap with those rollers used on gaff
mast hoops and put it over the boom, attach your dinghy block and tackle to that rollered sling. In that way you can push or pull the dinghy along underneath your boom to any position for and aft.
So lifting the dinghy out of the
water single handed would go like this: 1. Rig your rollered sling on the boom with your dinghy block and tackle attached to it making sure the rollered sling is secured fore and aft to prevent it from moving along the boom before you are ready. 2 Uncleat your main sheet and swing your boom way out over port or starboard directly over the dinghy. 3. Climb down into the dinghy and attach the lower end of the block and tackle to the dinghy sling that is attached to the dinghy bow and stern and take up on that block and tackle as much as you can while sitting there in the dinghy. 3. Climb aboard your big
boat and take up on your topping lift with a
winch until the boom is high enough for your dinghy to clear the
lifelines. 5. Your dinghy may not be high enough now but all you have to do is go over to the side of your
boat and reach in to your dinghy and take up on the dinghy's block and tackle to raise it some more. 6. Swing the dinghy inboard the lifelines, flip it, then position it over your dinghy chocks and then ease your topping lift to let the boom down.
With two people it is a bit easier and with removable lifelines and stanchion you don't have to lift your boom so high. When you have two people one person can lower the boom further toward the dinghy while it is out over the side. That makes it easier to lift using the topping lift. You probably noticed that I said flip the dinghy after it is inboard the lifelines. That way none of the valuables you have left in the dinghy bottom will go to Davy Jones. Once you've done it a few times you get an idea of how to make it quicker and easier and what other pieces of
gear might help. The ease of flipping the dinghy comes by having the two part sling tangs set just right. You don't want it flipping at the wrong moment so some experimenting might be necessary.
You also don't want to try and raise a very heavy dinghy on a weaker boom unless your topping lift is rigged directly onto your rollered sling. You don't want to bend your boom.
Sometimes drawing it out on a piece of paper helps me get a new
concept easier.
Hope this helps and good luck.
