I had a Davit on my 24 and 27 boats.
I put it back, through the Gunn'l, but not so far back that I lost my foot room. I had I/O's with only a foot or so for my feet back there.
Make sure you reinforce under the Gunn'l or you might have a terrible accident where the Gunn'l tears out!
Put the Pot-hauler motor down as low and out of the way as possible. Run a Cable, through wheel pulleys up the davit, and an easy to handle snap swivel at the terminal end.
I was hauling my lines, when I got something heavy hooked up.
The Pot Hauler motor bogged down, the boat heeled over till we had very little free board. Suddenly what ever we had hooked up, slid off the shelf it was resting on and nearly took us down with it as it headed down for deeper water.
One of the boys was quick, and got the boat headed for shallow water and we were lucky that day. The boat dragged that load up onto the shelf again.
It was a 700 Lb King Crab cage.
We had to keep dragging it to shallow water till we got another Grapple into it, the boys pulled it up till I could get the Hooks out of it, and we let it go back to his resting place.
The Boat nearly jumped outta the water when the boys let that thing go.
So....make sure that Davit is well supported!
