    My custom davits are just about done. We just have to blow up the dinghy and cut the boards. The blocks are aluminum, and the arms are SS. I'll get better pics once I have the boards cut, but I think this should work nicely. The benefits of my father owning a machine shop. IMG_0456.JPG IMG_0454.JPG IMG_0453.JPG IMG_0455.JPG

    Looking good - I am considering this type for my 340SDA but I have been concerned about the height of the swim platform. Do you think something like this will work with the added height?

    You might also want to consider adding a rubber (?) foot under the inside of the arm to prevent bouncing on the platform and/or to prevent unnecessary additional flex.

    Great idea on the foot, otherwise it won't be level

    I know your boat well as a good friend has one. I think the system would work just fine, but the required torque to lift the dink up will be quite a bit more that for ours since your angle would be much steeper. I think it would depend on the dinghy and engine combo. Ours is an airfloor zodiac with a 9.8 2 stroke, so total weight is under 200#. I can push it around quite easily. A RIB or 4 stroke might be tougher

    That's what I was thinking - might be easier retrieved with two people. My intended use would only be for trips where we would load before leaving and launch at destination and keep tied up. I already have the weaver mounts but no hardware and I think this method would be easier than the hooks and storing vertical. I don't have a dink yet but don't want anything to big either (probably around a 9 foot).

    I like keeping my swim platform free and clear and this type allows removal and storage.

    That set up looks a lot like the “Dinghy Ramps” that I have for my boat. They work really well, and yours should too.
    The only problem a I have with mine are my Dinghy and Motor Combo are heavy and a PIA to lull up. Dinghy weighs about 130 and the 4 stroke 9.9 weighs over 90 so it’s a 2 man job.
    I’m probably going to keep my eyes open for a good used lighter Dinghy and smaller 2 stroke to make it easier.
    Once up though, it’s a nice setup as long as you strap it down nice and tight.

    Same for us, it’s a 30’ boat in a 30’ slip so I don’t want to leave it on all the time. We hang at the dock a lot too so getting in and out of the boat through the transom is important.

    I’ve seen similar Davits available on eBay for like 500-600. Honestly, after how much time we spent making them I probably would have been better off just buying them, but what’s the fun in that.

    Sometimes the project is the fun part - even if it takes longer and costs more. It does leave you with a sense of accomplishment and lots of stories to talk about around the dock.
