Setting a 2010 cobalt 232 on a trailer

I am buying a used boat that does not have a trailer. I have an older shorelander tandem axle roller trailer thats in good shape. The manufacturer says this trailer can hold up to 25' boat. My 232 has a 22'6" length, not including swim platform.
I have adjusted the bow post forward. And the rear roller sets back so the last roller is 32" past the end of the trailer main supports.

The boat is at the marina, I am making these adjustments based on boat length.
I am hoping to go there Saturday and place the boat on the trailer.

1) the transom will sit on rollers that are 32" past the back of the trailer. Is this ok?

2) the rollers frame is adjustable for width.
Should they be under the stringers ? Does knowing the beam width tell you where the stringers are ? How do I know where the stringers are ?

3) I know weight distribution is important. Does the tandem axle give me some leeway to drive the boat home and move axles to change tongue weight as needed..

I have left the axles where they were set for a 19' Century 3000 I have.

Rollers sticking out is not an issue
Need to adjust the spacing of the rollers so the keel doesn't contact the cross members.

Beam is 8' 6"

Your boat has a 21* deadrise and I'm unable to find specs for Cobalt. So you have 21* at the bow and maybe 10* at the stern

ALLDODGE, thanks for your reply

So, by moving the roller sets in a little. That would elevated the keel if needed?
Do I need to be concerned with getting the rollers on the stringers ?

What about the tongue weight issue. Any way to know if the axles are in the ball park before I go to pick the boat up ?

Yes, moving in will raise boat, could ask shorlander about it and they could advise

Having on the stringers is good, but I wouldn't worry to much about it right now. My guess is it will be real close if not dead on, the boat isn't that wide. Once you get it home you can see how it goes. How far you going?

The good thing with tongue weight, is you have room to move the boat forward some

Yes, there is a few inches to move the bow stop.
I asked cobalt about the stringers he said not so critical but make sure the rollers dont hit the strakes. My rollers are 3" wide. Side by side with almost 6 " between them. I thought I might try to adjust the width so the rollers straddle the inside strikes.

My trip is almost 100 miles. The marina guys said they would help set the boat and make needed adjustments.

Thanks again for your input !

OOPS, deadrise is measured at the transom. And be sure to have a few hundred pounds of tongue weight. Otherwise you'll have the tail wagging the dog.
Rule of thumb is 10 to 15%, but many boats are a little low.
