Davits laminated from wood.

I havenít tried them yet...still have to sort out some chocks on the underside and some rigging.

The close-up picture shows a center hub with a slot in it...the idea is to hoist the dingy in the conventional way, then pass a cargo type strap under it....feed the tail end into the slot in the hub (similar to what you'd see on the sides of a tractor trailer) then crank it using a winch handle.
Hopefully this will sandwich the dingy between the strap and the under side of the davits, by lifting it and pulling it toward the stern, holding it very secure.

During passages when, the dingy will be stowed elsewhere and the davits can be turned in-board and dropped.


The horizontal 4" SS pipes have 4" wide X 1/4" SS plate inserted through their length in line with the davits, to keep the pipe from buckling.
It passes through the deck and is fixed to the floor of the lazarette

I canít wait to strap the dingy on and see how they work.

Wow!
Those laminated davits are a beautiful piece of fabrication.
The design is also intuitively elegant and artful.
Iíll be very interested to read your engineering report, after youíve tested them in use.

Thanks GordMay....I found it tough to come up with something that worked well will the canoe stern, Hard to go wrong with an arch.

Fortunately I'm not concerned about weight...these are heavy.

I went with a similar theme on the main salon hatch...but not laminated.

Are the forward and after frames steam bent or cut from a larger piece on that salon hatch?

I had a horribly bent and twisted piece left over from some other work....it was cut from that...I havenít done any steam bending, but would sure like to mess with some.
Have you done any? How was it?
This is my fridge box...its trim is laminated.
