Dinghy Crane Pulley/Hook
Anyone know where I can find something like this? I've been googling various combos of dinghy/Crane/davit/hook/pulley all evening with no success.
Thanks.

Easy to do with separately sourced/purchased parts: Multi-part block and tackle shackled to a suitable snap hook/shackle.
Your pic looks neat but there's only two parts to the tackle and that casting could CONK you good!

Try Googling "single sheave snatch block with hook." The trick might be finding it in stainless.

A sail rigging shop can "hook" you up.

Thanks for the input. I'm seeing some possibilities now, but none of them really look specific to hoisting a dinghy. Most are for much larger line that what I have (currently wire rope...thinking about changing to Dyneema). Also most are too long from the top of the sheave to bottom of the hook. I'm limited in length there in order to get the dinghy high enough to get over the rail. Also, none have the weight.
So I'm still looking. Any other ideas are appreciated.

Take a look at garhauer blocks with snap shackles. They are nice and compact and have decent working loads. I'm using some of their fiddle blocks for overhead lifting of a small whaler that is approximately 700 lbs.

How much load does it need to take?

Dinghy and motor are about 500 lbs.

That is the closest I've seen to what I need. Is that shackle going to be able to lift a 500# dinghy. The working load says yes, but it doesn't look that substantial.

Try something like this:
Harken
Max working load of 792lbs. Should give you plenty of safety margin as far as the weight.
Or if you really want to go big and pretty,
Harken
5000lbs working load and shiny stainless.
There are other manufacturers besides Harken that will make similar. Just add the hook of your choice and you should be good to go.
Those Garhauer snap shackle blocks look like a great solution.

You can get those with a safe working load up to 3500#. That should be plenty for a 500# dinghy and motor combo. Your crane will fail before the block/shackle will fail.

Make your own using an anchor swivel?

I'm think that might be the way to go. I don't see how to include the big stainless steel weight that I have above the hook now. These block/shackles are about 12 oz. Do I need more weight on the line than that?

I'm not picturing how to use that to wind up with a pulley and a hook. Never did have a good imagination.

Good question and I don't know. The hook on my crane is really heavy, not sure if the weight is important for the winch line to feed out or not. If you switched to dyneema, I don't think it would be.

I have the setup the OP is looking for but it is attached to my davit crane. And sure, one can make his own although the one shown in post 1 is HEAVY. I find that its weight is needed to pull the wire from the wench when lowering the hook. I doubt that anything light weight would be desirable.
