Dinghy Mount Mockup

Filed under: Dinghy — tomlarkin @ 2:46 pm

I bought plans for a 9 1/2 foot Nutshell Pram to use as a dinghy. I wrote about how I wanted to load it onto the boat a few weeks ago. Then I saw an 8 foot Bolger Nymph pram on sale on Craigslist for a reasonable price. I went to the Second Wave used marine store in Fremont to look at it, and bought it almost on impulse. I picked up some used Weaver Davits at the same time, and the shop owner threw them in for free.  The dinghy is pretty small, maybe too small to safely hold the two of us. We’ll see. In the mean time, I can use it to see if the plan will work. I still want to make the Nutshell if I think I can get it onto the Coot.

Original idea:

I mocked up the curved stern of the Coot from scrap plywood and screwed the davits to it, then welded up a hanging bar from some old rebar in the garage. I can lift the dinghy as per the plan, but it’s really heavy. Harder than I had hoped. I may need to set up the 3:1 lifting tackle I’d  considered earlier. I’ll also try moving the painter attachment point to the bottom inside of the front transom to improve the lifting angle.

Dinghy in floating position. The mocked-up stern of the Coot is to the left, at the stern of the dinghy:

Lift the back of the dinghy by the hanging bar and latch into the Weaver clips:


Standing on the stern (in this case the steel workbench), pull the bow line to lift the dinghy up, and flip it onto the stern of the boat. This is about as high as I could go in the shop before hitting the lights.  I’ll move the whole thing to the boat one of these days to try it out live:


If nothing else, I now have a nice little boat I can throw in the back of the truck for day trips.

  1. Hi there, I want to know about the safety tests that a boat has to pass before sailing? I have heard about some safety tests. I am also finding a boat repair company online.
