I planning on moving the axle forward to reduce the tow ball weight.

I have a 5.2mt quintrex caddy cab with 85 yamaha. I guess Hull weight is 700kg and motor aroung 150kg.
I can just dead lift the front of trailer so guessing around the 80kg
For the first time adjusting it how much should i move the axle forward? To make it a bit lighter at tow hitch?
What is the lightest i can have the tow hitch weight?

Any advice is appreciated

It will also affect your overhang allowance

My understanding is the tongue weight should be approx 10% of your trailer laden weight so 80kg is about right. If you have to much weight aft of your axle the boat will be prone to swaying

Thanks for that nude up
Maybe look at upgrading the spings in the back of the car them

definitely needs weight on tow ball, how does it tow? are you only moving it forward to make it easier to put on?

what vehicle do you have? Is the issue a weight distribution for towing? you can get some simple tow systems to spread the weight. I picked up a set of theses & had the trailer bracket welded to fit on the single draw bar.

This is not suitable for boat trailers, as they have a long draw bar, not an a frame.

Wolly you can fit them to boat trailers and they work very well. Hayman Reece have a kit with a bracket that bolts to the draw bar.

If you can lift your draw bar then it's not too heavy for the hitch. If you go too light up the front it will create sway and less stability. Also, when you try to climb into your boat on the trailer (unhitched) your boat will tip up and motor smash into the ground. It sounds to me like your rear springs are not up to scratch.

Another, easier option (with the same issues as above) is to more the boat back on the trailer by pushing the winch post back and readjusting the rollers/bunks. Easier than moving the axle. You don't want your transom hanging too far back either, ideally it would be supported by the rear roller but even 200mm can make a big difference to weight distribution.

I had to move my boat back on the trailer to lighten the ball weight but mine was up around 270kg on the ball. 200mm Made a huge difference to towing and launch and retrieve.

Wolly, I have a modified bracket to go over the single draw bar on the boat trailer, it works very well. I had an engineer weld & reinforce 2 of the Hayman reese mini brackets together to take the 80kg load rating, it sits over the draw bar in front of the winch post.

I think its is a better option than moving & realigning axles.

Great on my long trips when I load up the boat with all the gear, camping stuff, jerry cans etc.

Some of the options are:
