I think all boats and trailers will be a little different so if it were mine I'd start working the axle(s) back till you had required tongue weight. There's a lot of thing that play in to it, how much gear you keep stored aboard etc.
This is a Parker site , and the 2320 with the 8.6 beam is trailerable
So I figured I should be able to get some help here, or atleast a starting poing of how far back I should slide the 2 axles! :wink:
Yes, it is a Parker site, but it is a Parker owner's/lover's site, not to be confused with the Parker Marine Inc. site. We all do the best we can, and from what I've gethered here so far, people only pipe in when they have real experience to add. On many other boating sites, you will get a noise:signal (value:BS) that is too high. Too many opinions, without experience to back it up.
If you didn't get a response you expected, I'd suspect that no one who has encountered your problem and solved it, has seen your request for help.
I'll do my best...
When I took delivery of my boat, the trailer tongue was too light by a couple hundred pounds (needs to be about 7%-10% of the total boat & trailer weight. The dealer moved the winch stand forward about 6", and then dragged the boat up to it. That put it in the range, and has worked well since.
You can't do this, so moving the axles back it your only option. Here is what I'd recommend:
Weigh the boat and trailer (with a normal load of fuel and fishing gear). Calculate 7% and 10% of that weight. That will give you the range you are looking for. Weigh the tounge weight, and find the difference you have to add to reach the 7% value. Get a transient slip for the day and launch the boat. Go back to the trailer and move the axles back 3", load the boat, and determine the tounge weight. If you are at or above the 7% value (and not exceeding the 10% value), you are done. If still too light, you have something to work with. That 3" added some weight to the tounge. Divide that weight into the difference you get when you subtract your current tounge weight from the 7% value you determined earlier. That should give you a multiple of 3" increments you need. If it is close to 2, then you need to move it back another 6". If it is close to 1.5, then you need to move it back another 4.5"...etc.
As was said before, each boat and trailer combo is different. Torsion and leave springs will act different on the tounge loading. The only way to do it right is to get some figures, make a move, and do the rest of the calculations to get you in the ball park.
Of course, you could take it back to the dealer, or a trailer sales outfit, and pay them to do it for you.
Sorry...but this is what I can offer that is within my experience and knowledge range.
