trailer axle position

[krazyfisher]

No real point moving it if you dont Know if it is wrong. I thought my tinka had tha axels too far back but after putting the boat on there was no need to move it.

[FishHunter]

Ok ok you have convinced me to try it as is About to pull all the bolts and apply some never sieze before I go apeshit with the Lanolin, just waiting for a civilized hour before I unleash my rattle gun

[FishHunter]

I now have a very well conditioned patch of grass Hope the lanolin washes away quick before the landlord arrives.

[FishHunter]

Tada!
Axle is miles too far back I had to jack the trailer up to get the jockey wheel down.
Will fight with it tomorrow, also need to even the rollers out as its a bit lopsided at moment.

[krazyfisher]

looks good though

The reason they put the axle soo far back is....they have to put it somewhere

AND

Lots of boats are very tail heavy on the trailer, particularly open aluminium boats.

On my new trailer I have the axle, pretty well as far back as it goes, and that is about right......but that is an open ally boat.
There is more drawbar weight with my trailer unloaded than with the boat on, beacuse of the big grey lump that is bolted to the back.

Remember on many alloy boats the outboard weighs arrond as much as the bare hull.
Remember also your boat will weigh quite a bit more than the trailer and almost all boats that plane are weight ballanced with centre of gravity in the rear third of the hull length

you have fibreglass boat with a forward driving position and a part cabin..that moves a hell of a lot of weight forward.

This is why we have adjustable trailers.

I had to move the axle 700mm forwards to get into the ball park. I haven't weighed it yet, the jockey wheel needs to be shortened so I dont have to use a jack to get the trailer off the towbar.



A better one

[oldboot]

Shall we run a book on how much REELHAPPY goes over the scale it.

Lets hope she comes in under the tonne.

I'll come in and say....890KG

Always expect a surprise at the weigh bridge when you take a boat

you can buy swing away jockey wheel kits where the jack is not yet welded to the swivel.

OR just have at it with some delicate grinder work and reweld it lower down the outer tube.

Oldboot, I recon 1250kg with the trailer.
Lets see eh.

If thats all it weighed I have wasted my money on buying a trailer with a BMT of 1750kg.
I would be ecstatic if it was under 1600kg. Webster reckons around 1400kg in his magazine.

[Feral]

I'd be taking it for a trip up the highway at 100kph before deciding it was finished, just to make sure the arse does not start swaying, it looks a bit far forward now!

Its not finalised buit its very close, I cant lift the front end of the trailer at all so the I would say the towball weight is around the 100kg mark and the old rig towed just fine with similar weight.

I still plan on sticking a scale under the towball to verify whats going on

Do it when you take it to a weighbridge. Position the vehicle so the wheels are just off the weighbridge get that result. Lower the jockey wheel and wind off the towball get that result and the difference is the towball weight.

i've got the same trailer under a 17ft viking
on mine the next roller in front of the rear triple swings is in line with the middle of the front of the tyre
i think i also moved my winch post
mine's 8yrs old also lanoxed it
have had to replace the rear cross member as the drain hole eventually clogs up & rusts out
made the new one watertight
cheers brian

Yea Ihad to move the winchpost about 500mm and raise it about 150mm to get it where it is now.
Having a slight drama with the rollers as I cant lower the rear cradle and the front keel roller is at its max hight and I think it should be a bit higher. Anyway I will carry on fiddling untill everything lines up and it rolls on and off easily
