Re: What do you use to lift a dinghy with davits?

I had custom davits made from two inch aluminum pipe.
I thought about an electric winch but I needed a backup.
Instead I chose a stainless steel hand winch designed to lift 1000 pounds.. It has a built in brake to hold the load.
I used SS cables and wound them both on the winch from opposite directions.
I can use one arm, but it is easier with two, to lift my 12 ft RIB, with 20hp electric start Honda, plus battery, fuel tank, two anchors, anchor lines, and safety equipment

Take a look at this article I wrote for Cruising World a few years ago. It might give you some idea of how you could mechanize the system. This motor lifts my own 10’ RIB and a 60Lb engine in about 30 seconds.

If you want to lift it rapidly, you can use a winch with block n tackle in reverse. Pulling the blocks apart multiplies the speed of line intake. flight-deck arrester cables do that !.

Personally I sold the quality tender and went for an old school Avon inflatable, quality without the weight
Then removed the Davits and just lift and throw the tender on the bow.

Re: What do you use to lift a dinghy with davits?

Garhauer or Shaffer roller bearing 6-part block sets. We bought at the boat show">Annapolis boat show. The total set including the blocks, swivels, cam cleats, lines and big snap shackle was purpose made for dinghy lifting and very affordable.

Keep it simple. Nothing you can’t inspect and easily repair.

Re: What do you use to lift a dinghy with davits?

As others have said, we use Garhauer sets for ours. And YES, leading them correctly will make a HUGE difference on how much friction there is. It does look weird with the blocks at right angles, but it works! Nicholson58, you might try changing yours.


We have a scoop stern. So, we had our davits built so that they can articulate out. Works very well too!

Sorry, that was supposed to be Gerhauer out of California.
We have our Davit system for 3 yrs, so easy to DIY!
