Mast/Tabernacle attachment O'Day 19

[RTSKI]

On the mast-tabernacle step, are the plates held together by one or two pins?
The connection on the O'Day 19 is made with what appears to be a flat metal plate on the bottom of the mast, but in reality it has turned down edges on the sides (like a very shallow inverted "u") which mates with a similar plate on the deck. Both plates have holes in the four corners through the edges, through which a pin fits, i.e. one pin crosswise at the forward set of matching holes, and another pin could fit crosswise through the aft set of matching holses. I presume slightly larger boats would use a similar system.

I purchased the boat last fall, just put it into the water. Prior owner stated only the forward holes are used for a pin, and that there was never a pin through the aft set of holes. I question the accuracy of this. Putting a pin through the aft holes makes it a lot easier to raise the mast single-handed, and why would there be holes in the aft portion if it were not intended for a pin to secure the mast while underway?

Also, appear to have lost the connector between the boom and the mast. Any suggestions for sources?

It sounds like you have a Dwyer mast. Yes, you should have 2 pins for the fore and aft end of the mast step. You can get them from Dwyer https://www.dwyermast.com/items.asp?cat1ID=40&cat1Name=Hardware&familyID=18&familyName=Hinges Should probably be the DH2151P pins. You should be able to get a gooseneck from Dwyer as well, but on the other hand, D&R Marine has full goosenecks listed, original equipment for the 19: http://www.drmarine.com/products.asp?cat=144 You'll probably need to call them and speak to Rudy Nickerson about which actual pieces of the gooseneck you need, whether you need the complete gooseneck, or just the slide, or the reefing hook as well.

Just use one pin in tabernacle hinge plate. 2 pins=damage

If you have the Dwyer Hinge plate on the tabernacle or any other similar for that matter, use only ONE PIN- either forward or aft depending on which way you step the mast. The pin / hinge / tabernacle plate merely centers the mast and helps with stepping and unstepping the mast. You don't want to use two pins and may do damage if you use two. The reason is that you want the mast to flex on the tabernacle- and if there are 2 pins, the tabernacle will most likely start pulling out if the deck. Two pins won't hold the mast anyway- if it did- there would be no reason for standing rigging. It is the standing rigging that holds the mast up. Just use one pin in the tabernacle hinge plate. Way too much stress on tabernacle and mast with 2 pins.

Use the back pins.... only. If for some reason the mast comes down, it is the same motion as raising and lowering the mast. If you use the front pin and the mast comes down, up come the glass with it. At least that's what I have been told. I had an F27 and it only had rear pins. Havn't raised the mast on my 222.

Uh oh!

Good info Mitch and Eric!

I got my 192 with both pins in, and it was a PITA to get the forward pin out to unstep the mast.

Since I'm splashing tomorrow, I will only keep the aft pin in after I pivot the mast up... My other boats either don't have a tabernacle, or have just a single pin centered in the mast...

Thanks,
Brian

My O'day 25 had two pins in the tabernacle when I got it and the mast supposedly had not been dropped by the PO. Who knows what the orginal owner did.
I just checked the manual and it says to step the mast from the bow and put the pin in the front hole to act as a hinge for stepping the mast. It does not say anything about putting in a second pin or moving the pin to the back hole.
Putting the pin in the stern hole does make sense if you set the mast with some rake towards the stern

I forgot to mention. I checked two resources. First was the 192/222 rigging manual, which says pivot up on aft pin, and then insert forward pin.

Then I called Dwyer Mast. They were somewhat bemused by the idea of one or both pins. I said the idea if the mast comes down, only one pin blah blah, and he said it's kinda six of one or half dozen of the other.

I suspect that if I part a stay, and the mast comes down, there's going to be serious problems with major repairs.

Right now I just have the aft pin in place, but I'm probably going to put the forward pin in, just so I don't lose it...
