I finally have the basics done; 2" aluminum bent at 70 degrees. It slides over 1.5" base pipe. This is the rough fitting with steel blocks attached with straps. Rick

I turned the base from ipe and mortised it into an ipe base. The angle of the base matches the side deck slope.

I made the cabintop bracket out of ipe as well, but it wasn't strong enough. It didn't break but I was pushing the limits of it's shear strength. Also, it wasn't broad based enough when the crane swings forward.

Another view of the ipe bracket.

My welder made this for me. It spreads the load both vertically and horizontally.

Rope stropped blocks ala Gervy Smith.

Fully rigged.

With dinghy attached. My plan is to have the aluminum powder coated a soft buff, like the decks. I am interested in your opinions. This was a seat of the pants project. Rick

I just looked at the thread title; it should be "Dinghy Crane". Anybody know how to change a thread title? Rick
Very cool! Now you need a Seagull Motor for that keen dinghy!
You could change the title to "Dinghy Davit". How long is that long boat?
Jay
Where will the clete to tie off the halyard while you swing the davit inboard be located? On the davit, I hope.
Nice job!

Hi Rick, looks good to me. Putting a dink on the roof is a good idea. I am planning on putting two kayaks on racks up on top of my BJ 271. Not sure how much or if we will use a dinghy.

I have experience owning powder coated aluminum boat parts, not fabricating them. My experience in a coastal environment has been that after a few years--i.e, a ding or three--the finish bubbles and peels.
FWIW.

This new ship here is fitted according to the reported increase of knowledge among mankind. Namely, she is cumbered end to end with bells and trumpets and clocks and wires. It has been told to me she can call voices out of the air or the waters to con the ship while her crew sleep. But sleep though lightly. It has not yet been told to me that the sea has ceased to be the sea.--Rudyard Kipling
Willin', I have indeed mounted a cleat on the crane itself. The best way to lift is from the cockpit with the mate on the cabintop to fend off and guide. That's on the trailer at least; we'll see how things go afloat. It's definitely a WIP (work on progress).
Breakaway, I figured powder coating would be more durable than any enamel. Truthfully, there is very little exposure to a marine environment; we do multiday cruises on fresh and brackish water. The rest of the time see sits on a trailer in a barn. Rick

Stevenbauer, your method definitely did not work. Multiple tries finally got the thread to Misc but when I moved it back it reverted to the original title. An iPad thing?
Jay, ain't no seagull on the back of that dinghy! Oars only. I am a Lin & Larry disciple despite the powerboat. Rick
Seagulls are awful!! Nice dink, and nice crane. I probably wouldn't powder coat it though.
