Thread: Trailer swaying help.

  1. #16

    Re: Trailer swaying help.

    The possibility of moving the boat forward or axles rear is pretty much zero, so if it is a weight to the rear issue, the only solution I have is pushing any of the loose load forward when it gets loaded up.

    It's hard to estimate the weight on the ball. I'll put it on flat ground tomorrow and try to get a better estimate. The heavy duty jockey wheel certainly needs some forearm to lift the Treg hitch up.

    Use this method but don't use the pipe bit as it rolls just use very thin timber.

    Don't know if this helps.I put a set of digital scales on a hard surface under jockey wheel while hooked to the car.Then wound down jockey wheel lifting trailer coupling off the tow ball which gave me the exact weight from the jockey wheel forward which was 85 kilos.Roughly 10% of estimated boat and trailer weight.

    A guess based on nothing more than an unskilled look and a scratch of the nuts - the axle could be a foot or two further back. Not much help I know, but that motor looks a long way back.

    What rating shocks are you using to control the bags and coils?

    If your load rates are bad you could cut and shut the trailer just behind the foreward keel rollers and add length there. Looks easy in the photo - haha

    agree with GBC, and the way to measure the weight with the scales. My gut feeling is that you need to move the whole axle back, a fair bit.

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^

    I designed the trailer based off of the dimensions of my previous steel trailer which was balanced just right.

    GBC the shocks are a OME Nitro charger chock. I have them on too steep an angle at the moment and will rectify this soon.

    I think we might be missing the obvious a bit here. Is it really necessary to load the boat up so much? Especially with regard to 150L of fuel. Can't you fill up at your destination?

    That and keeping the speed down a bit should do the trick.

    NB, a lot of trailer tyres are only rated to 100kph.

    Yeh it is very necessary to load it up so much. The 150L of fuel was 50L in rear of the boat and 100L in the trailer fuel tank (takes up to 160-180L from memory). It is my all in one off-road boat and camper trailer set up.

    I take it the box above the axles in the first pic is your fuel tank, can that be moved further forward on the trailer up near the winch post maybe?

    Re: Trailer swaying help.

    No Marto the mounts are welded in place and the main beam has been cut to allow the drain plug to sit flush into the frame.

    It seems that having too much weight rear is part of the problem though. With an empty boat on the trailer with a full fuel tank (sits in rear of the boat) and roughly 60L in the trailer tank, I can lift the trailer by hand(about 80kg lift).

    When I go up to Tuan next week or so I will load any loose weight forward and see if it makes a difference.
