O'day 23 dimensions needed for trailer set up

[Ziradog]

I just bought a 1978 O'day 23 and (separately) a dual axle trailer to carry it on. I need to do the rough set up on the trailer before I go get the boat with it. fortunately, the boat is out of the water in a boat yard & will be placed on the trailer by a lift, making the final adjustments easier. Can anyone tell me the following dimensions from their trailer? I am assuming a trailer with the boat sitting on its keel on a board, with 2 bunk boards to stabilize it. Each bunk board will have 3 uprights, bolted/welded to the cross beams on the trailer.

So, using the top of the side rails of the trailer as a datum, how far above or below is the board the keel sits on?

Starting at the bow, how far back are the first, second, and third uprights located?

How tall above the top of the side rails are the first, second, and third uprights to the bottom of the bunk boards?

How far out from the center line are the uprights located?

How wide is the keel at the widest point (or how wide is the board the keel sits on)?

How far in front of the front axle is the bottom front edge of the keel?

Thanks for any & all advice.

Here is a craigslist ad from guy from NC selling a O'Day 23 that has trailer out of the water. Go measure it.

Thanks but...

Thanks. I actually looked at that trailer (and that boat). It did not fit the boat (the keel does not sit on the bottom) He bought it used and had some extra uprights put on it, and it has multiple bunk boards on each side that do not really fit either. .

Not relevant, but it is way to light a trailer for the boat, with an axle rated at 3500# gvw. I would not be comfortable moving a O'day 23 on it for any distance.

Hi Ziradog
Here are a couple of pics of my 23-2 set up for your reference.

The full weight of the boat is on the formed steel keel plate, the side pads are for stability and are adjustable, great for hull painting, tie off one side of the boat then lower the other side pads for full access, repeat for other side when dry.
This trailer was original with the boat and is great.

Nice trailer design

That is the best trailer design I have seen.

Re: Nice trailer design

I agree that is an awesome trailer. Is the roller in front of the keel plate a "stop" for the keel? can you tell me how high above the keel plate the center of yuor pads are? That would at least get me started.

Thanks.

Yes I put the roller on for a soft keel stop.
I adjust the pad pressure so that I can just turn by hand the pads against the hull. I cross strap the hull when trailering to reduce sides loads.
The tongue of the trailer extends out about 5 or 6 feet to allow the trailer to get deep into the water, this is a great asset and works so well.

I will measure the pad for you.
