G`day one and all. Have a query from a client which needs answers from people much more knowledgable than this little black duck. He is going to take his 4.5 mt aluiminium boat & trailer up to the Kimberleys, it has a 50hp outboard hanging out the back & is on one of those standard boat trailers.He wants a stone gaurd on the trailer to protect the boat, that is easily solved. Will the normal numbers of rollers and support pads be enough to support the hull? Do we need to remove the outboard,[ weighs approx 120kg], from the boat? Trailer only has 13 in wheels, his ute has 16in wheels, do we need to fit shockers to stop a lot of the bouncing on the corrugations?Do we need extra tie downs on the boat ,so that it is securely held on the trailer? In anticipation, many thanks. Regards Bob

I'd be inclined to remove the outboard and carry it in the vehicle, then the trailer should be ok with basically an empty boat, Fit 14" wheels/tyres (spares much more available in remote areas), shockers wouldn't go astray but might be hard to fit, extra padding and additional tiedowns wouldn't go astray either.
Very few boat trailers are designed for much more than the trip to the boat ramp from suburbia.
Depending on the trailer it may be easier to make a heavy rectangular frame with cruiser leaves (some removed to soften the ride), solid axle and 16" rims compatible with the tow vehicle. After the trip the original setup can be restored.

Bob, I am no specialist on what you have as a question but agree mostly with the answers above. I don't even have a boat larger than my kayak. Al-Ko have rebound spring packs that may so some extent obviate the need for shockers and as you would have a relatively light load should cope. They are actaully listed as an Outback Pack and have some damping built in. I reckon the suggested 14" or better still 15" is the way to go and to reduce the pressures to reduce shocks. I think I would rather have the boat on top..........

Mate i would not even consider taking a "Standard" boat trailer up the Gibb River road.
I live in Broome and spent 6 years working along the road as a Field Mechanic for the main roads dept, During the busy season i would say that 4-5 nights a week after finishing work i would be carrying out repairs to trailers/vehicles etc off people that had found them selves in a spot of bother.
Any one thats lives up here and loves there fishing end up getting there own custom made trailers H/D trailers made.
Take a normal trailer up there and it's going to end in tears..

i agree Jolly, I'm in Karratha and am in the middle of building my own costom trailer for a 16ft. Don,t even consider taking a 'standard' trailer past the 26th parallel.

I agree with Jolly,
Your looking for trouble....with great expense. Your so called holiday will turn to a horror time very quickly.

Here Here,
If in the middle of the season even the graders cannot keep up with the corrugations. so any boat/trailor must be hefty and do not forget the ever present dust over the trailor.
I used to have a handle on life, but it broke.

Cheers Dodg.

If your client does decide to take the standard trailer ensure he has spare springs, spring hangers, rollers, hubs, bearings, wheels and tyres and the ability to carry out 12V welding as he will probably need most of it...... It would probably also be a good idea to make up a for sale ad or the boat before you go as I would think the hull would be stuffed after 600km of corrigations on a standard trailer.

G'day Drew,

A mate of mine recently bought a tinnie that travelled on a trailer in that neck of the woods AND guess what it has stress fractures and bent ribs. Just reinforcing the point you make. The cracks were where the rollers reside on the trailer - has got it all fixed now but a lot of damage if not properly set up.

Kind regards

I have to agree with Jolly on this one.
If your client absolutely has to drag a boat all through the Kimberley I would only recommend a tinnie sitting on a roof rack. That way the boat is upside down and the corrugations will only damage to topside of the boat and not underneath.
There's trailer parts strewn all over GRR by end of season and that doesn't take into account all the stress fractures that have to get repaired back at home.
I would make use of the fishing charters that are readily available in this part of the world before dragging my own.
Hope this helps

When I read your question I thought there might be some negative answers.

I agree with the advice above not to even dream of taking a boat on a standard trailer to the Kimberley.

For a start, the tyres on the trailer won't last 5 minutes on the GRR.
The back of the boat is going to hit the road repeatedly on crossings and jumpups. The trailer will fall apart. The boat and motor will be damaged.

Hi Bob
Agree with all other replies, but if you do beef up the trailer the strongest part of the boat is the keel so you need to put a full length skid on the trailer to support the boat along the keel.
Don't leave the weight supported by rollers or you will be asking for trouble.
I see lots of boats with outboards still attached on Cape rd but you must have a good support bracket and drive to the conditions.
Having said all that I would still be a bit concerned about towing, as the road conditions can vary greatly from season to season.
Cheers Poppy
