    Offroad boat trailer

    I am toying with the idea again of beefing up the Suspension on my trailcraft trailer so that I can get into some more remote places.
    Has any one done the same thing on the forum? If so can you send through some photos of what you have done.
    I am thinking along the lines of 15'' wheels rated springs on greasable shackles and heavy duty axel.
    I want to keep it a single axel due to the boat ony being 5.5 mtrs.

    Thoughts???

    Mate.
    Have a look at some of the pics already in the fishing shack.
    Dont recall the thread title,but there were some great pics,not many to search!!!
    Isuzurover is looking at doing similar if that helps the search,he was one of the posters in the thread.
    Looking forward to your upgrades,I have the same trailer,looking at extending the drawbar by 300mm,incorporating a swing away extension and dolly wheel.

    Cheers Andy,

    Will keep you posted.

    Just have to wait until we move back home to Moora end of January so that I can get my boat back in the shed. As you would know you can't touch any thing with out getting third degree burns in the Pilbara sunthis time of year. I want to add a fold away extended draw bar and third wheel as well.

    pilbara,
    the trailecraft trailers are a reasonable platform to start with.
    Unless you are prepared to axe the chassis width though you will be limited by the wheel track.
    In soft conditions mud or sand having the wheels track outside the 130 will be your rate limiter to excellent offroad performance.
    I have conveted a few from where yours is to acceptable.

    First, pull the suspension bogeys. Make up some new ones to accomodate 78 series tojo rear leaves. For that rig just lose the heaviest overload leaf. IMO stick with the 14 in rims and light truck tyres. Otherwise you will raise her high but still not gain the track benefit that makes a boat trailer truly offroad. Run a pair of shocks from axle up to brackets that beef the side boat rails. For a rig that size i would consider nothing less than Ford slimline hub and bearings and even still they will need reg work. If you run bigger tyres they will flog nearly every reasonable offroad trip. Also consider better keel support. From hazy bad memories of my old mans short affair witha traily a solid hard wood timber keel rail would be appropriate

    Im happy to send pics of a 4.5m makocraft with 60 4st i converted recently.

    Regards,
    Steve

    Thanks for the info Steve.

    The roads that I am looking at taking are more corrugation than undulating ground. I realy want to get up to Kalumburu and do a 2 week mission from there.

    Would be great to see some pics of your set up.

    Cheers

    If that be the case.
    Stick light truck 14s on. Change out the springs to something that actually provides suspension. Short trailer springs are evil for corrugations! Support the hull better.

    I'll grab some pics of the mako raft trailer when I get home to cook town.

    Sorry mate super slow to post these ups. Springs are from 79series rear with heavy load leaf removed. Dampers are 79series cruiser rears. Bottom mount welded to 45mm solid axle. Springs mount to 50x50 angle 4mm which is U-Bolyed to chassis rails. Channel and scrub bars are essential to get trailer round tight tracks. Keel supported by hardwood - hard to beat for offroad support.

    Great job mate thanks for posting the pics.

    Ive now moved back home and the boat is in the shed so its now on the list to rebuild it after I get all the jobs around the house done to keep the old girl happy

    What size is your boat ? Im wondering if my I beam trailer will go the distance for strength I may need to beef it up with a couple of cross beams and extra rollers.
