Garhauer Davit setup questions

Warren,

Here's a photo of some Pit-Pins. You can see the metal balls near the tapered end. They extend out just far enough to prevent the pin from being removed from a hole that's just barely larger than the pin shank. When the button on the handle end is pushed in, the balls retract and the pin can be removed.

They're used primarily in military and aircraft applications. They're hard to find. Surplus stores may have some.

Warren and Dr. Bob
The support bracket I used is listed on the Garhauer website under radar tower accessories. It is the last item listed.

Warren,

For those pins, try: http://www.mcmaster.com/

Search for: Push-Button Quick-Release Pins

Note that most of the pins shown are available in stainless.

In fact McMaster-Carr is a good source for all sorts of generic stuff applicable to working on a C-Dory. When you see the index, you'll know what I mean.

Ball-Lok Quick Release Pins are available in stainless steel for marine applications, and often used on sailboats. They're pretty expensive. If you can find a military surplus type of store, they often have non-stainless ones for a lot less.

The best kind have a raised guard around the release button to guard against accidental release. This surrounding guard has a hole drilled along one edge of it to attach a seizing line so as to securely attach the pin somewhere near where it's used so that the pin doesn't become lost.

Ball-Lok- Quick Release Pins Note correct spelling is not "Lock".

I found this thread and wanted to bring it back up to ask a question.

I am getting a lifting davit for my CD22 to lift the kicker from the transom to the dinghy.

The question: What do you think of mounting the ball foot for the davit on one of the factory cockpit floorboards?

It seems to me that the force applied to the ball foot and the floorboard would try to push the floorboard into the cabin bulkhead or try to lift the opposite end of the floorboard. With the support collar I don't think it could move or lift the floorboard much. I don't expect to be lifting more than about 60 lbs but if I needed to haul in a large person aboard I would not want it cause some unexpected problem.

Anyone have any thoughts on this?

Thanks,
Steve

Hi John,

Answer and pictures within minutes!

I have been looking at your pictures for mounting the motor bracket but did not look at the next page where you mounted the Davit.

I thought the davit should work okay with the mount on the floorboard but was not 100% positive. My set up will be very similar to yours.

Thanks,
Steve

John (of Swee Pee) --

You have the Garhauer davit mounted on the floor boards and mention the possibility of cutting a wedge and adding another mount in the motor well. If you were only going to have a single mount to move a dinghy engine from the dinghy onto a transom mount on the C-Dory, would you prefer it on the floor boards or in the motor well. Your thoughts please.

Jim

I have been thinking about this for a while. With the davit mounted in the port and starboard corner of the boat, on the floorboards, it is the perfect place structurally and the easiest install. However, the arm of the davit does not reach directly over the kicker. Should not be too big of a problem - I don't think. I haven't used it yet to lift the kicker. I have always put the motor on the mount in the driveway. Laughing

If I had my druthers and the sole purpose of mounting the davit was to lift the kicker motor, the ideal place would be the motor well - directly over the kicker. Just my opinion.

I have been looking to mount a third ball/and collar in the motor well so the davit pully is located directly over the kicker. The only problem is that in order to bolt through the motor well in the location I want, the gas tank is in the way (for the ball mount) - there is no room for a wedge to level the ball mount in the sloping motorwell. I thought about mounting the ball without a wedge whereby the davit would be leaning over towards the stern at a slight angle. Again, the gas tank is in the way. I do not believe that there is enough clearance for the backing plate and a nut between the gas tank and the bottom of the motorwell.

I am going to look and think some more. I possibly could have a bracket made to mount the ball onto then mount the bracket onto the boat inside the motor well. I don't know if it is worth the trouble.

Sometimes the obvious solution is in the mind of another. Wink

Take a look and see what you come up with. Maybe the solution is so simple that I didn't think of it. Let me know.

John --

Thanks for the fast response. The tank was giving me issues as well with a motor well mount. My thought was to put the base as close as possible to the vertical side of the motor well which is the starboard lazarette and a bit aft in the motor well. I have been thinking about epoxying a piece of 3/4" plywood to the motor well on the upper side and filling the gap between the plywood and the vertical side with thickened epoxy. Then, epoxying the wedge to the plywood base and setting the davit base on the wedge by drilling oversized holes in it, filling them with thickened epoxy and dropping machine screws into the epoxy before it sets. I have installed cleats in this manner (machine screws into thickened epoxy in oversized holes) on another boat and it worked well. My thought is that I have never feared to stand on the motor well and I am 200 pounds. Therefore, if the davit has something on top of the motor well to spread the load a bit, it should be able to take the less than 100 pounds I will be lifting with it. The one concern I had was that the upper ring bracket support for the davit is not very high at about half the distance above the base that it would be with a mount on the floor boards.

What had me thinking about the motor well mount was the length, even of the longer arm, and the inability to have the end of the arm over the motor to set it on the bracket. The counter is that with the davit taking most of the load, it should be relatively easy to pull the motor out (aft) so it will land properly on the motor bracket.

So, like you, still puzzling! Thanks again.

Jim
